FEB. 2-3th, 2005 - Home station project is sort of finished. I am finally QRV from JO20iv on most bands. It ain t the greatest, but it may help you to get ON/JO20 squared away, even on 6cm! Now I need to get started on the /P station again..... first things first.

Band	Antenna system	Amplifier power out	Preamp	Equipment	System NF estimate
70cm	18 element	75W	SP-7 SSB	ic-910 barefoot	1.2 dB
23cm	67 element	150W	none	ic-910 + dk2fd	2.0 dB
13cm	67 element	40W	none	db6nt + surplus + tm-255e	2.5 dB
6cm	60cm dish	8W	none	db6nt + f5hry/f6dph + tm-255e	2.8 dB

OCT. 5th, 2004 - I modified the LA0BY spreadsheet for Openoffice/Linux and included the SHF beacons. Download xls sxc .

ON4KUL/B MAR 28th, 2004. The 10368.975 Mhz (actually more .970+/-) beacon in JO20iv is back. The location is not too good though, reports appreciated contact information. UPDATE 24/8/2004 - temp. QRT.

Station description

Skeds welcome for portable operations on all microwave bands 23-13-6-3-1.2cm, Belgium and surrounding countries.

TECHNICAL

Z3801A frequency standard statistics.

Yeasu FT-100 PTT delay: This small circuit will delay the PTT signal of your FT-100 transceiver so there is time to switch the transverters and amps into transmit. PCBs are available. Easily adapted for other transceivers too.

I may be able to help if your problem is related to HAM microwaves: maybe you want to use something from the lab (well - not much there probably). Maybe I have something in my parts inventory that can get you on the air (lots of cables, semi-rigid, WR-42, ... ask).
It is a shame that things DO NOT GET USED. Share the goodies!

2003

I was pretty active this year. European grids activated were JO20 and JN29. Several interesting contacts, particularly during summer and autumn, thanks to major station upgrades, primarely on 6cm and 1.2cm. Thanks all for meeting me on the bands!

I always tried to participate in the French JA on Sundays.
