Hello! Very pleasant autumn/winter so far with K2/100 on the Topband.
Yesterday I took my K2 home for re-alignment. I noticed that KAF2 was making my RX worse. I wonder, if there is some problem with low-pass filter or other part of KAF? I will check soldering and components later. Audio filter has been most unused option in my radio. Normally it doesn't help anything. It doesn't help at all with weak signal RX. I left KAF2 out when I put radio back together. I used unmodules to replace it. Otherwise K2 seem to be now in better condition. I re-adjusted IF-amplifier. Also did all CW filters with spectrogram. Now I set 1.5 k, 700, 450 and 100 Hz bandwidths. Before I had OPT1, 700, 400 and 200 Hz. Now I can hear signals with 100 Hz setting, before at 200 Hz it was quite useless. I also checked VCO voltage for 160m, never checked that after K160RX was installed. I remember that it should be also 1.5 - 7.5 V. Bottom of band is OK around 3.8 V, but when go up to 2000 kHz it is over 8 volts.It is below 7,5 V on the band segment which is used here (<1900 kHz). Should I make adjustment? Waiting for better conditions to make more observations of re-aligned K2.
