Unexpectedly OM0A the month again spoke to 144 MHz, and this JN99eh. This elevation on the border of Slovakia and the Czech Republic has Rádioklub Manin built facilities. This makes the transmission very nice. Nevertheless, we agree, if you are on a hill electricity, homeless, antenna and also to good company, it's priceless!

The idea of ​​World Records Day I Joey OM4AQ addressed in advance, because I know, that they 144 MHz band are deleted due to noise. Yet close to the station as kW OM6A, OL9W or OM3W and others. QRM about the race wrote years ago excellent analysis OK1VPZ and the topic is still possible to find many other articles and measurement equipment.

We dusted 17el.F9FT antenna and a modified FT-847 with Tubes PA. We, however, we woke up at about 40% his options, for reasons of interference and also the, that with this TCVR the third from the amplifier more power or can not get.

FT-847 It is a handy little TCVR, which has MDS – 142 dBm, BDR (20 kHz) 103 dB a IMD 88 dB. IP3 point at -11dBm. The device listens well, no sound when debugging colored towards the heights. It's probably due to DSP technology, that the edges of the filter produces a ringing effect.

The advantage of this TCVR-and the CAT interface, what is the connection to the PC and PA through microKEYER very simple.

I anticipate the rain from Trencin, But I Will not. Due to the traffic situation I came to Jožka OM4AQ to the 13-th and the hill we got up in the rain. that Government OM3BY He had unfinished F9FT antenna. Since we have information from meteoradaru, so we had a break and we have already completed the antenna together quickly. Jožko OM4AQ had set while working.
