All comments welcome. You may need an external pre-amp. See several books and web sites for=20 circuits. Your insulation should not be a problem on receive. I forgot to mention that I get some advantage from driving Argo very=20 hard - well into the red zone - and via a crude limiter (back-to-back=20 diodes). The AF distortion introduced is counter-intuitive but it has=20 been found by me and others (Jim, M0BMU calls his limiter a Hendrix- izer) to gain a dB or two in SNR with only a small increase in=20 background noise.
