I meant to post this to the TowerTalk group. It still may be relevant to

Very interesting and timely discussions on radials and ground conductivity.
I’m currently rebuilding an 80M broadside array (with shortened, top loaded
elements) in SW Utah that I’ve modeled at 12 ohms impedance. The current
antenna was tested and the impedance measured was 25 ohms. Each element
Thanks for all who responded. I’ve taken the liberty of sharing my response

I have 4 identical short verticals (part of a broadside array) where EZNEC
predicts a 12.5 ohm feed-point impedance. That seems reasonable, but my
actual measurements indicate 25 ohms at resonance.
My first thought was something lossy in the ground system. The ground
system consists of 32 copper
I operate a vertical antenna for 80 & 160M where the bandwidth is such that I
need to switch in reactance between the phone and CW portions of each band. I
currently do this manually, but am installing vacuum relays for switching
remotely. Is there a way the K3, through the data port or
There was a recent thread regarding the internet bandwidth required to support
full K4 remote operating requirements. I have operated my K3/K3/0 combo from
all corners of the world with mostly good results, but those results are highly
dependent on speed, bandwidth and latency.
Comparing to
Makes you wonder how K3/10 users fair running high duty cycle modes at full
output. I’ve replaced two sets of LPF drivers running 10W WSJT on my K3/100. No
more! Now I advance the power until the amplifier engages (~12W). Hopefully
this reduces driver dissipation.

I operate remotely with a K3/KPA1500 via the RemoteRig boxes. Internet
bandwidth on the RF end is great, but as we travel, the operator end is often
quite marginal. It appears the K4 will be sharing considerable information
between the RF and Op end over the internet connection. Is there a

I can’t locate the physical dimensions for the KPA1500 and PS in the .pdf

I’ve been remoting my K3, KPA500, KAT500 station via the RemoteRig boxes and
K3/0 mini for two years with solid results. Later this year, I want to make
several enhancements, including the replacement of the KPA500 and KAT500 with a
KPA1500. The amp/tuner should be a fairly straightforward

I run a 10 watt beacon on 28.2985. Tuning across 144.302 (K3 + internal
transverter), I hear an S9 image of the 10M beacon signal. My first thought
was maybe some sort of harmonic so I installed a low pass filter on the
beacon. Still S9 on 144.302. I brought the low pass filter into the shack

I have a Motorola Maxar, plate number D31TRA2300AK
I scanned through the Repeater builder site and didn't find many hits on
the model.
I want to put this on 6M - any experience on how difficult it would be
to insert a 6M crystal set/realign?
Any thoughts or referrals would be most appreciated

I placed an order for a K3/100 yesterday. It looks like an April/May
delivery, but given all I have heard from this group it will be well
worth the wait. Now to sell my OMNI VI+.
