Comment: It was very fine contact. Serge hrd me FB however we made it after our 2nd test. When he got from me 20dB burst, he was so excited, so he start running with his GS35 PA on full power. As the the result was damaged tube & PA. The question was, should we continue? Of course, so he run on the roof and put on his small driver PA from Mirage with 100W output. And at last, I got "034900 10.6 160 1 26 50 R RRRRR", so contact was completed. Any conclusion from the test? 70cm MS is very depended on precise frequency of your TRX. S50C, OK2POI and UT5JCW were ok on 432.370,100 (100Hz above +-) however SM2ILF, SM2CEW and SK2AT on 432.199.400 more then 600Hz below the sked QRG. Is it due to some bad reference? 73 de Matej, OK1TEH
PS: Some words about 1st 70cm MS tests from Chris, GW4DGU: ...I agree with you about MS ops not being patient. In the 1970s, as G4DGU, I ran many 6hour skeds trying to make a complete QSO on 432. Despite having 1kW, a very good single loop yagi antenna and one of the first GaASFET preamplifiers in Europe I failed to do it, although I was heard and heard other people many times. I didn't make my first complete 432MS QSOs until I came back on the air 2003. -> Chris, do you have any idea about the 1st 70cm MS QSO ever? In the 70's I did a lot of tests with Karl, SM3AKW. I think the first 432MS QSO from these islands was an expedition station which included my friend G4VVZ/G4ZAP to EI (IO61!) in about 1982. I now think that was probably aircraft scatter, as it was only just over 1000km... ...The longest burst I've ever heard on 432 was from SM3AKW and was 35s! When I worked Karl in 2004 on HSCW we had several bursts <10s! mni tnx Chris & cu in Geminids! 73 Matej, OK1TEH

The view to my screen before our 1st 70cm test with UT5JCW, QRM/QRN level was "low"..
UT5JCW - antenna for 70cm - 4x 28el M2 -> OK1TEH - antenna for 70cm - 23el DK7ZB - QTF 110
