Update 3/05/2021:
I had
some radio fun yesterday and today with a local "Antique Wireless Association"
QSO party. I fired up an old Yaesu FT-200 for the occasion. Yesterday it was
AM only and today SSB. The AM section was quite a challenge, the radio only
outputs about 25W on AM and AM is so noisy due to the large bandwidth it made
QSO's difficult. It must have been tough working voice DX before SSB!
I am looking at procuring a small HF set that will
run 100W for use on SOTA and POTA expeditions. In the past I used a QRP radio
but with current band conditions it is quite difficult to make the minimum
number of contacts running 5W, yes, CW helps but we have so few CW operators
in this country you do need to make some SSB contacts and that needs more
power.
A radio that has a low RX current consumption is also important
so I still need to do some research on that. At the moment the Yaesu FT-881
and FT-991A are on the list. The one is nice and compact and the other has a
nice display but the display eats power!
I did have a FT-991 (original
model) a few years ago and I liked it but the problems users were having with
blown finals and the fact that it did not have a real-time spectrum display
made me decide to sell it after a short time. Both those issues have been
solved in the FT-991A but the RX current consumption is around 2A!
Need
to do some more research.
I did hear a Russian station on 20m CW this
afternoon but he was low down and did not hear me, I miss the days of bands
full of DX.
Since there is so little DX to work I have been chatting to
local guys more often, I had quite a few long CW QSO's this week and I enjoyed
it. Today I also had a nice chat to some locals on 40 and 80m SSB, might just
do it again.
Update 29/04/2021:
With winter approaching
I will be looking at activating a few local summits again soon, it is just too hot in summer
to go climbing mountains here in this part of Africa!
I am now also interested in POTA (Parks On The Air), since I have quite a few
parks that are quite close to my QTH I think it is time to activate a few.
First I need to find a list of park and their POTA numbers, if there is such a
list for South Africa.
Another dead day on the bands. I again called CQ on 20 and
15m and again I was heard in South America but no takers. Is CW dead unless
there is a competition or major DX-pedition? Sure looks like it as the bands
are open with no activity. Quite sad actually, well maybe SOTA/POTA can add
some interest even if it is just local, I need to find something interesting
else the hobby will soon go back into hibernation for a few years. I will see
how much activity there is for the end of May CQ WW WPX CW contest, if I can
keep my own interest up that long......
Update 26/04/2021: The HF bands have been shockingly
bad! I do hear DX on 40m in the afternoon but mostly SSB. Conditions are the
worst I have heard since 1996. I called CQ on 20 and 15m today. I was spotted
(by Skimmer) , with a strong signal, in South America and the far east on 20m
but no replies. I think everybody has given up! I did eventually work a AU2
station on 20m CW but his signal was right in the noise.
Locally 40m is
wide open most of the day making 5W CW contacts easy. The problem is that
there as so few local CW stations. I enjoy a good chat every now and then but
it would be nice to not just chat to the same few people every day. In the
evenings 80m is open locally but I have not heard any CW activity, only a few
groups chatting every night (and in the morning) on SSB.
I am quite
keen to go climb a mountain to activate a SOTA peak but I would really love to
work some DX from the summit, does not look like that is going to happen soon.
We also have some local POTA activity, also fun and at least you do not have
to climb a mountain. Will see if there is a park I can activate locally just
for fun.
At least some of my other hobbies are more productive! I
captured the sunrise below this morning, and yes, I did have to climb a
(small) mountain to capture it!
Since the bands are so dead I have been spending some time cleaning up a few
old radios and putting them back on the air. The last few days I made QSO's
with a FT-901DM, FT-850 and a Kenwood TS-120. They have all been gathering
dust for years! Next I want to see if I can get a few sick radios back on the
air. This includes an old FT-107M that I suspect has blown finals. I also have
a TS-930 that is just dead, pretty sure it is a 5V regulator issue. I also
have a pristine FT-990 with a 6V (I think it was 6V) regulator that keeps on
blowing, must be a short somewhere. And then there is the beautiful FT-767GX
that goes into TX the moment you switch it on and refused to go back to RX.
Sounds like my soldering iron is going to be busy, perfect for the
coming winter days that are too cold to go "play" outside!
Update 19/04/2021:
We had a small local "Sprint" style
contest yesterday, both SSB and CW but only on 40m. I used the opportunity to
get to know and test the little R928 Plus. She performed well and I must say
the RX is really great even in a crowded band with lots of VERY strong
signals. I did struggle a bit competing against many 1kW stations running only
5-7W but is was still fun. It did make me wonder if I should not maybe add a
small amplifier, maybe running 50-100W for those days you are out portable or
on a SOTA peak and conditions are really bad.
I know this will require
more batteries but I would rather have a few QSO's and then the batteries are
flat than no QSO's! Especially if I have just climbed a mountain. I have lots
of LiPo packs I can use. Will see what I can find.
Yesterday was also
World Amateur Radio day so locally 40 and 80m were quite active. I managed to
work many SSB and CW stations on the little R928 Plus, must say I have fallen
in love with the little radio!
I cannot believe how scarce DX stations
are at the moment! I know I do not have my large antennas up yet but band
conditions are really bad, plus I think unless there is a contest many guys
are hanging out on the FT8 frequencies as I can hear lots of signals there.
Someone said a while ago FT8 (and the fully automated operations possible
running FT8) is killing amateur radio. I am starting to think that person was
correct....
For the last few days my only DX QSO was a LU8 station on
40m CW, times are bad.... I am going to have to think very carefully what my
band-contest strategy will be for the coming CQWW WPX CW contest. Maybe I will
do 40m, or even 80m only as my noise levels are now so low.
Update 16/04/2021:
This morning at about 7am we had a power outage. Since I had just completed my
EFLW antenna I decided it was the perfect opportunity to take it out into the
garden and test it. I connected 17.5m of wire to the output of the unun and
made 8 x 4m radials. The feed side of the antenna was attached to a low branch
of a nice shady tree and the other side I ran out to another tree and attached
it about 3m above the ground. I wanted it low incase I needed to trim the wire
a bit.
The MFJ antenna analizer showed that the antenna had SWR dips at
40m, 20m and very low SWR at 15m but all the dips were just below the bands. I
trimmed the wire a bit and tried again. Eventually I removed about 0.5m of the
wire, the dips were now inside the bands but other than 15m the SWR was too
high to use just like that. I connected a MFJ manual tuner and tuned the
antenna, now it was easy to match on all bands.
I experimented a bit
with the radials, by far the best result was with the radials attached to the
ground lug of the tuner and not to the unun. I then connected my trusty Yaesu
FT-817 and listened around a bit. Since it was still early in the morning only
40m showed signs of life. The FT-817 was running from internal batteries so
max power out was no more than 2.5W but soon I had made a few QSO's on CW and
SSB with good reports. The antenna seems quiet and works better than what I
expected after I saw the rather high SWR on most bands. I briefly took the
FT-817 inside and connected it to my 40m dipole, the WFLW seemed to give
better results, on RX anyway! Maybe I need to check the feed line (rather old)
to the dipole, it is MUCH higher than the EFLW so it should produce better
results.
Anyway, went outside again and made another QSO. I was just
finished when I heard my name being called, not on the radio but from my gate!
I was rally glad to see our local courier lady, she had my R928 Plus!
I
had it unpacked and running in no time! What a nice little radio! I did
disassemble it to check all the solder work. I am glad I did, I found the
screws holding the PCB's together were loose to the point of falling out, the
PCB's would not have moved but the metal screws could well have caused a
short! I also found that the USB-C port had dry solder joints on the shell,
this allowed a small amount of movement in the connector that would surely
lead to broken connections. I re-soldered this carefully, everything now seems
nice and solid!
Once I had it reassembled I ran into a problem. I
normal CW key worked fine but when I tried to key the radio from a computer,
using a standard interface I have used for 25 years on lots of different
radios, I found that as soon as I plugged the interface into the computer the
radio would key and not unkey until I unplugged again. I checked all the
cables and connectors but no-go. Seems like there is tiny bit of current
flowing even when the "contacts" in the keyer (transistor switch) is suppose
to be open. It has never bothered and other radio. This is rather frustrating
as for contesting I use the N1MM+ logger and the keyer that goes with it,
After testing a few other keyers I decided that this is not going to work
without some mods to the radio or the keyer....
But there is another
option! You can also key the radio via the USB port, I tried this and
everything was up and running.
By now our power was back and I was in
the shack playing with the radio and making a few contacts. First impressions
are that the RX is really great and it seems nice and selective and not
bothered with close-by strong signals. On CW the filters are really nice with
steep skirts, far better than most of the other radios in my shack.
I
still want to upgrade the firmware to the latest, it has really old firmware
and then I want to setup everything from the bias to the EQ and power output
on all bands. Talking about bands, this radio has the Si5251a synthesizer so
it will go to 6m, I tested it there and it does TX, it might also work on 4m
and 2m, it does RX there but I need to check TX, first I want to make sure the
bias on the finals and output limits are fine as oscillation could be a
problem on the higher bands.
R928 Plus up and
running
I think I
am going to love this little radio!
Update 14/04/2021:
The new R928 Plus did not arrive
today as I hoped but I can see on the tracking system that it is close. One of
the very few disadvantages of living in a rural area like I do is that
"Overnight shipping" can take a few days.
I spent some time this
morning cleaning and started assembling my A4S yagi, it has been almost 18
months since I took it down! All seems to be well, I was hoping to assemble it
all the way and redo all the measurement but by 10am it was too hot outside to
work! Does not feel like it is almost winter! After I abandoned the yagi
project I quickly built a 9:1 unun. I want to use it for a EFLW antenna that,
if it work well, I hope to use for future portable QRP operations. I did not
even put it in a case, want to try it first and only if it works well will I
make it a bit neater. With a bit of luck I can test it tomorrow in the garden.
Late afternoon 40m opened locally, during the day I listened a few times
on the bands but they were SO dead, not even weak DX! Anyway, had a nice CW
chat to a few locals (around 1000km away, the old FT-817 feeding the 40m
dipole is still doing the job! Hopefully when the R928 Plus arrives the bands
will be in a reasonable condition. At the moment my main shack radios are
getting neglected a bit but that is ok, soon we will start preparing for the
WPX CW contest.
Update 13/04/2021:
Good news! The R928 Plus has been
procured and it is on it's way to me! I have been doing a lot of research on
the radio and reading manuals and everything I can find on the software.
What I find really exciting is the fact that the firmware is open source.
Lots of people are contributing to the project and the radio is really packed
with some outstanding features! I will also have a look at the source code and
maybe customize it a but to suit me. I will be fun to do some programming and
compiling again!
R928 Plus, not my photo!
As soon as the radio is here I will take a few photos and post them here. Then
I am going to upgrade the radio to the newest software before I start testing
to see if it is all I am hoping it will be. The more I read about this little
radio the more I like it! Exciting times ahead, a new "toy" like this might
just be what I need to fan the "radio adventure" spark into a fire again!
Update 12/04/2021:
I have been keeping an ear on the
bands but conditions are not great. The only interesting station I managed to
work was a 5Z in Kenya on 40m CW for a new band/mode slot.
Locally
there seems to be a lot of activity on 80 and 40m and even on 60m. I very
seldom join in with the chats but I did "force" myself a few times to pick up
the mike and chat, was more fun than expected! I have also been working a few
local stations every now and then on CW, also fun.
I was surprised at
how well my G5RV works on 60m! It is a band that I have never used but it
seems to be nice and quiet with little noise but strong signals at my QTH.
I have identified a potential radio that can supplement or
replace my FT-817 and give me the more modern features I want. The radio is
the mcHF SRD radio or one of the other versions of this radio (it is open
source so to call them clones is not correct) that is made in China. I did
find a R928+ locally that seems to be a good deal. It is the newer version
with 1mb flash memory and an internal Li-on battery, perfect for future
upgrades and portable operations.
Let's see if I can secure this radio!
Update 10/04/2021:
We had a local QRP contest today.
Initially I thought I would just listen out and work a few stations but the
thought of a QRP station and specifically a QRP field station brought back
some really good memories of past operations and contests. When I was still at
school I got my hands on a CQ magazine (the were not available from the local
book shop), think it was from a guy at school who's father was a ham. Anyway,
on the front cover was a photo of a guy sitting in a dimly lit tent at night
with small radio making contacts.
I remember the article going with the
photo described making QRP contacts with minimal equipment and talking (CW) to
people around the world. I think that photo and article was the main thing
that sparked my interest in amateur radio and specifically QRP. I have always
been a nature lover and hiking plus camping has always been a favorite
past-time for me. So combining hiking + camping with amateur radio was a
natural thing.
Anyway, back to the present. I have not taken a radio
into the bush with me for many years, lots of reasons for that including
health and lots of work pressure but things have changed for the better so I
an really excited to do it again.
I did use my FT-817 over the weekend,
it is a great little radio but I do miss some features that I know more modern
radios have. One of the main things is a spectrum display, yes, I know it does
not really fit in with the minimal equipment QRP way of thinking but time has
moved on and so should we. What I really missed was the ability to see
activity away from my current frequency. This allows you to see and QSY to a
new station when you see home and not spending most of your time turning the
VFO dial up and down the band.
So the question is what is available
that is small and light enough to work for me?
I did also notice that
my old fan dipole for 40/20/10 is not really working that well anymore, at the
moment 10m and even 20m is useless most of the time so I need something that
will cover 80/40/20 and maybe 15 and 10 if needed. I know this might need a
small tuner but I am ok with that.
Time to do some research.....
Update 07/04/2021:
I got up early this morning hoping
for a nice sunrise to go and shoot a YouTube video, alas it was not meant to
be as the predicted clouds never materialized. I then listened around the
bands and found a nice pile-up caused by C92RU on 80m. I was quite surprised
to work him after only a few calls running 5W CW into my 89m dipole!
I
did hear him later during the day on 21MHz as well but the signal was really
low so I had no chance, maybe tomorrow?
This evening he was just above
the noise on 40m, I think I switched on a bit late as the band was already
closing. He had a HUGE unruly pile-up from EU, I am sure he was not having
fun, lots of LIDS in the bunch when kept on calling, tuning, not running split
etc.. Anyway, it took me a while but I did eventually managed to work him
before the band closed. I think both 40 and 80m CW contacts are new QRP
band/slots for me. At least the bands are not totally dead!
Will be on
the air again tomorrow, also still have a IC-738 and a FT-990 to sort out as
well. The
IC-738 should be easy but the FT-990 developed a short somewhere on the 5V
line after plugging in a CW key while the radio was on, now the 5V regulator
keeps on dying. It is an old but nice radio with great filters so I would love
to get it going again.
Update 06/04/2021:
I spent some time today working on
a few radios that have been in the "radios with issues" pile. The first one, a
Yaesu FT-901DM from my antique radio collection just needed a decent cleanup,
mostly the switches, did a quick align and all was well. The RX is amazingly
good for it's age and a lot quitter than some modern radios. I am glad I have
to old lady going again, will use it on the AWA net this weekend if conditions
allow.
Next up was a Kenwood TS-930S also from the classic radio
collection. This radio had had an intermittent problem with the PLL unlocking
when it get's hot. I have reset the PLL voltages a few times but the issue
kept coming back. Today I found a few dry solder joints. The era Kenwood
radios (930/940/950) really have dry-joint issues! I found documentation from
Kenwood showing lots of through-plate issues on the PCB's! I managed to get it
going again and used to chat to some guys on 80m
for about 2 hours. All seemed well. Shortly after saying 73 it died again!
This time no display at all! Well, I have had enough of it for now, back to
the "trouble makers" pile it goes, maybe sometime in the future when I am
bored.
Next up was an Icom IC-728, got it as part of some deal a few
years ago but never used it. When it gets hot the frequency will suddenly jump
0.5Hz up. Went through the checks but could not find any problem. I then
noticed that when this happens if you toggle side-band it is fine again. I
cleaned the side-band switch but I am not convinced that is the problem. Will
watch it for a while. Problem is I never use it for long, I really dislike the
radio, the RX is pathetic and the filters non-existent. I just want to make
sure it is ok before I dispose it.
Update 05/04/2021:
I spent quite a bit of time
listening around the bands the last two days and I must say it is rather
disappointing! When there is a contest I do hear signals but mostly quite
weak, when there is no contest the bands are dead. This solar minimum is
really a bad one! Yes, there are some local stations chatting on 40m and 80m
but that is not really my thing! I love working DX but these days the pickings
are slim. Yes, I could use FT8 but that is so boring I would rather do
something else.
If things do not improve in the next day or so I think
I will disconnect everything again and put the station in hibernation for
another year or so......I am quite sad actually, yesterday was fun and I was
all fired up to get really active again, but it was only local and the bands
are as bad as they were a year ago.
Update 04/04/2021: Yesterday
we had a RADAR contest, (Rapid Deployment Amateur Radio) I volunteered to be
one of the monitor stations, the idea is that you monitor a single frequency
and answer calls from the moving stations. They make 5 contacts from a
location then they have to move a prescribed minimum distance. You can find
more information and the rules here:
http://radarops.co.za/index.php/radar-rules/
The plan was that most
stations would be active from 14h00 to 18h00 local time but there could be a
few outside that window. I ended up monitoring most of the day but the band
(40m) was quiet. After 14h00 things started picking up, first a few very weak
CW stations, most of the time in the noise but conditions slowly improved and
by 15h30 there were quite a few CW and SSB stations around.
I
volunteered to monitor both a CW and a SSB frequency, this turned out to be
fun especially towards the end when both frequencies became busy.
I
decided to use the IC-7610 in "Dual watch" mode, I have not really used the
radio much in the past so I decided it will be a good opportunity to get to
know it since I am planning on competing in the CQ WW WPX CW contest end of
May. I need to decide what radio to use long before then and use it for a
while since I have not really been active for so long. Well, the IC-7610 did
well, I am more than happy with the performance.
Icom IC-7610 in action
Dual
frequency/mode operation
I have not decided on what band/bands to compete in the WPX contest but at the
moment I am considering a 40m only QRP entry. My logic is that it will allow
me to add to my DXCC 40m totals (much needed!) and because there will only be
band openings around sunrise/sunset it will limit the time I need to spend in
the contest, I do not really feel like a 48 hour contest at the moment!
I will keep an eye on conditions on 40m, if conditions are bad as we get
closer to the contest I might change to a different band or even all bands if
conditions are really bad.
Well, I really had fun in the RADAR contest
and it has re-awakened my love for amateur radio, CW and contesting,
thanks Eddie (ZS6BNE)! Maybe I will try being a mobile/portable station for
the next RADAR challenge, sounds like fun.
Update 02/04/2021: Seems
like I have neglected updating this page for such a long time! Shame on
me..... I have not been very active for the last year or so. Band conditions
have been really poor so I have changed my focus to other hobbies but I have
been switching on the radios every now and then and even made a few contacts.
With the first sunspots of the new cycle starting to appear I cleaned up my
shack today and redid some wiring. I now need to het some better antennas up
in the air.
I did put up the 80m antenna I was planning as well as a
few other wire antennas including my trusty G5RV. Suddenly making 80m contacts
are a lot easier and I even added a new DXCC entity on 80m without even
trying. Think I will concentrate on 80m this coming winter!
I am
planning on competing in the CQ WW WPX CW contest end of May, I am not sure
what bands yet but I might just go for 40m or even 80m simply to boost my DXCC
standings on this bands. Let's see how preparations goes....
I have
been making a few FT8 contacts out of desperation on the dead bands but I have
to admit I find it totally boring and after a few FT8 contacts I seldom switch
the radio on for quite a while, it actually dampens my enthusiasm for ham
radio.
While dusting off equipment today I put the old FT-1000MP mk5 on
the air, the first time in a year and what a pleasure it is listening to the
analog RX, think it is time I add a few classic radios to my collection.
Update 26/01/2020: I have
been spending time slowly getting the shack sorted out. I am still waiting for
shelving to be installed so the radios are simply
stacked but it is functional at the moment.
I have been making a few CW contacts, mostly local as I still only have a
40m dipole up but I hope to change that today. Band conditions are rather poor
so I am in no mayor hurry to get the yagi's up for the higher bands. At the
moment I am having fun on 40m and hopefully I will have a 80m antenna up soon,
something I have not had for many years!
The local CW interest group
led by Mike ZS6MSW had an activity period yesterday from 4-5pm local time on
40m, I managed to make a few contacts. great to hear so many local CW stations
on the air!
The ZS2M call is slowly but surely starting to sound right
on CW but I still have to stop myself from sending ZS6DX every now and then!
More than 20 years of sending ZS6DX will take a while to unlearn....
As
I am slowly unpacking radios and connecting them up I am trying to give them
all some airtime, fun as I have not used quite a few of my radios on the air
for many years! This morning I connected up the Yeasu FT-1000MP MK-V and tried
it on the air. What a nice surprise! I have forgotten what a nice radio it is
and how effective the filters are on CW, the APF filter is really great and
still better than many modern SDR based radios. I am glad I added the old
beast to the collection after my original FT-1000MP expired.
Update 10/01/2020: The furniture
has arrived and along with it the antennas and coax. We are still waiting for
the truck with the vehicles...
I am still waiting for my tower(s) to be
installed but I have managed to get a pole up about 8m high with a 40m dipole,
I will add other dipoles soon. The first few contacts have been made with the
ZS2M call, mostly CW with a few FT8 contacts to check propagation.
Noise levels in general are quite a bit down compared to the city, that is
great news! Now I need to get more antennas in the air. The shack is also
still a mess, at the moment it is only one radio, a Yaesu FT-950 on a desk in
a room full of boxes! Things will improve with time.
Update 01/01/2020: We have finally moved! Well,
kind of, still waiting for the furniture and motor vehicle truck to arrive,
that should happen around 9 January. Busy getting the house ready for the
unpacking job, unfortunately no time for amateur radio yet, but soon....
