On the subject of 50MHz, Wayne, please could you say more about the 
receiver sensitivity specification?

At present the sensitivity spec is the same on all bands, namely: "-136 
dBm (typical), preamp on, 500Hz b/w". Assuming that figure represents 
the noise floor, it is more than adequate for HF (and maybe even 'too 
good' for the lower bands); but in VHF-speak it translates to a noise 
figure of 13.6dB, which is less than stellar.

Could you comment, please?
