Hi Jim, When I lived in Melbourne Florida, I had an 920 KHz AM station with a four tower array a short distance from my house (I forget the exact distance, it was probably on order of 1/2 mile). The

Steve, Does the switch produce an S9 spike on any transition of the switch (i.e. from position N to position N+/-1) or only on a certain subset of switch transitions? That might provide a clue as to

I am glad to hear T88WA is not at the hotel club station. The club station has a low dipole on 160 which in the past has made a poor showing. I managed to get a response from P29RO on 160 meter FT8 o

Remember, Steve, for a given frequency more capacitance equals less capacitive reactance [Xc = 1/(2*pi*f*c)]. At 1825 KHz, 5300 pf is only 16.5 ohms reactance. That means you are only offsetting a sm

People are driven by different things. For instance, I would be lying if I claimed I wasn't competitively driven. And I can tell you that at points in my life it has caused me to "lose perspective".

When we tried operating in 160 meter contests from W6UE in Pasadena, it was amusing to see the packet spots complaining about how deaf we were. We were running a full size flat-top dipole at 90 feet.

I just occurred to me that my description of the receive situation at W6UE is backwards. The 160 meter flat top dipole improved the 80 meter receive noise floor from really deaf to pretty deaf. On 16

In the case of that 160 meter dipole it was almost always better as a receive antenna for 80 meters. It was better at rejecting ferocious local QRN than the 80 meter inverted-V. Absolute signal level
