Jag hade S9+30 i utslag på S-metern här i Vbg på min ICOM ICR71, jag har en lw på 300m riktad i rakt öster oavslutad. Jag lyssnar emellanåt på MV-NA-stationer när det är cx, men det är ganska dåligt just nu när det är solfläcksmax. Här nedan ser du ett utdrag från sändningen lördagen den 5/2-00.

A pity we couldn't make the QSO. Your signal was excellent as you can imagine. The plot from spectrogram showed the AGC in my system suppressing the background noise during your transmission. I have never seen this effect on any non G station. You were, on average, just 15dB below DCF39 and showed about 10dB variation in QSB over the 15hr period. Very well done to you both. I look forward to one of the more interesting "weekend reports" Perhaps you could let us know the eventual TX pwr and antenna current along with the other details. ################################################################################## Hejsan VLF "expedtionen" gick bra till Kråk ?

Ur signal strength was more than 200µV on my 18mtrs inv-L antenna. I tried to contact you on 137kc , but unfortunately you didn't hear my calls. Sorry. My loc is JO30OL, qth near Bonn, close to the river Rhine valley. best 73 and good luck Dieter, DK5PT ################################################################################## Lech Laszkiewicz wrote: > > De G3KAU > Worked Chris 7S6SAJ both ways on 136.6KHz this morning, 06/02/2000 at > 0357utc. Chris was rst 599 plus 10db, he gave me 589. Chris called CQ > several times, but no takers. Must be the case of "early bird catching the > worm" I listened in on that QSO and copied 7S6SAJ with about 529 on a 160m dipole that was buried in the trees (we had some severe storms the last couple of weeks, so all our antennas are damaged) Anyway, it was the first ever ham station to be heard on 136kHz - so it was a great inspiration. Hope to have a transmitter up very soon now... --Magne / la1bfa (operating from LA1K in JP53EK) ################################################################################## Colossal signals this afternoon from 7S6SAJ, here in SW England using my regenerative Rx and piece of wet string.... 59+9 and by far the strongest signal I have ever heard on the band apart from G3OLB who is <20km away from me. QRM from the Greek RTTY on the other sideband was easily clobbered by the signals from Sweden, as was my local mains QRM which normally makes reception impossible from dusk onwards. 73, Kevin G1HDQ. ################################################################################## >From HB2ASB, JN36PT Strong signal, same level as the Greek station on 135.75 73 de Toni ################################################################################## Hi Christer, hi all, beautiful kilowatt signal here in Bavaria (JN59NK) today at 1410: 7S6SAJ 33 dBuV/m, G3KEV and G3YXM both about 4 dBuV/m. 73 de Markus, DF6NM ################################################################################## Hello friends, I worked 7S6SAJ yesterday afternoon. Currenty he is 40 dBmicroVolt/m here in Slow-CW, which is the strongest ham-signal I have ever heard! 7S6SAJ is "only" 45 dB weaker than DCF39 here, but he is much further away (700 something km vs. 120 km)! So well worth to give it a try over there at the other side of the big pond! Vy 73 Geri, DK8KW (W1KW) ################################################################################## The strongest signal that I have ever heard on 136 khz. 7S6SAJ was S9 plus plus with his 210 metre high antenna. The only other signal on the band nearly as strong is MM0ALM. Who says large antennas are not necessary and have little advantage over loops or low slung long wires !!!! When EI0CF was using his work QTH antennas he was also an extremely strong signal. These stations are only using modest output rf power. Chris might be using higher power but the antenna launching the signals is the prime factor. I heard numerous UK and other EU stations calling but did not succeed in making a qso. With an antenna like that also on receive one wonders why they were not heard. In the light of this experience the chances of a transatlantic qso are nil except those interested make an effort to improve the antenna height. Increasing the rf power, although helpful is not the ANSWER. 73 de MAL/G3KEV ################################################################################## Geeees what a signal!!!! go for it state side!!! Congratulations! 73 de Ivan HA5TS ################################################################################## Hej och tack för kul QSO Christer ! Jag gav dej RST 419 vilket stämmer ganska bra. Jag hörde dig på min 83 meters loop på taket av 4-våningshus, men du hördes bäst när jag bara tog emot på mittdelaren i PL259, allstå ojordat. Men så kunde jag inte sända (vilket jag gjorde av misstag) utan fick ha en hand på PL259 och skruva ur kontakten så bara stiftet gick in och en på nyckeln och det blev lite besvärligt vid skiftet. Men vi fick QSO OK. Sändaren och nycklingen lät mycket bra. Beträffande anropssignalen, så tycker jag 7S6SAW hade varit bättre. Jag vet att SAJ stod för några kortvågsfrekvenser men SAW på 86,6 kHz var vad vi i handelsflottan förknippade med Karlsborg Radio. Men OK ändå. Var det din sändare ni använde ? Och jag blev inte riktigt klar över vilken antenn. Var det 86,6 kHz-antennen eller ? Hörde du sade något om antennhöjd till någon, men hörde inte höjden. Som sagt, QSA 2-3 QRK 4, ärlig rapport. 73 och hälsa SM6CTQ och SM0AOM.
