Re: Hermes Lite - General coverage RX performance?

Mike et al,
Can anyone suggest a better 2m rx than the fcd?
I have tried many and have yet to find one that comes close.
Some are awful.
Although not a true sdr I am looking forward to trying the new demi 4 band transverter with my Anan especially when the microwave 4 band add on is released. Again that will be a hybrid rather than the 100% sdr I would prefere.
