I have just finished K3 ser # 39
As well as having an interest in HF/CW I am a keen 6m Operator and do
EME on 6m from time to time.
My antenna is a M2 6M7JHV at 60 feet fed with Ecoflex 10, in total about
120 Feet of feeder. I use no masthead preamp.I am in a quiet rural
location
with my Icom IC-7800 with the widest roofing filter and preamp1 on I can
hear several dB of band noise from the antenna over a Dummy load. A
quick and unscientific test by ear with the K3 shows that it too can
hear band noise on the antenna, perhaps not quite as much as the 7800
but I think the K3 will be sensitive enough for serious 6m work.
If I get a chance during the week I will take some more accurate
measurements with a signal generator and stepped attenuator.
Thanks for some genuine data, Brendan - looking forward to some
measurements too. I will be able to make NF measurements when the K3
arrives, but that won't be for several months yet.
