I am now using my IC-706 directly on 136kHz, with a pre-amp/filter
and this works fine.
hi Mike,
what antenna are you using for receiving ?
I'm using my transmitting antenna and found that I can add up to 40dB
attenuation between antenna and RX (Kenwood TS440) before the bandnoise
hits the RX noisefloor. I have 20dB attenuation all the time to prevent
DCF39 from overloading the RX input (and causing IM products).
I tried some preamps in my 'early days' on 136 but found them only a source
of aditional IM products.
