Title: PE1MPH: F6AQK and 9H1ES (3709 khz) Post by: pe1mph on March 14, 2015, 02:09:56 AM Hello AM Lovers, AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
This morning I awake aearly.... I thought: 'Lets try to make a qso on 80 mtrs in AM'! With a (hot) cup of tea I walked to my studio.... The tubes were glowing (transmitter and modulator) .... and later I were on air. I used the 'France' crystal 3710 khz, but.... when I listen... A terrible sound on that freq.! I listen by a webreceiver to check the freq.: http://sdr.radioandorra.org/ I saw a 'wide line' on the 80 mtrs band. Between +/- 3710 - 3713 khz I heard the audio-noise!!! So I did using the (little) usa crystal from 3709 khz, but... Not easy to get it working, it takes some time to get that crystal 'locked'. I tried with a variable pf to get it a bit lower in freq. But when I did that, the crystal did not working anymore... While I were busy I heard Jean F6AQK calling to Fortunato 9H1ES. I wait.... and very short I did say hello and my call. Hi, hi.... Jean did heard me! Later I had a qso with F6AQK (France) and 9H1ES (Malta) in AM. Here the results: - F6AQK, Jean, max. S9 +20, nice audio - 9H1ES, Fortunato, max. S7 I needed to listen in narrow bandwide, because on 3603 very strong ssb. And on 3710 the terrible noise.... Jean were comming nicely out my speaker(s), but from Fortunato I missed a lot. Therefore I listen evenso in ssb mode to hear more words from Fortunato. Pretty to hear Jean and Fortunato, both are big AM-lovers! This morning I heard no AM from the USA around 3885.
