Instead of a remote tuner, why not remotely switch in either doorknob caps and/or Toroid inductors. Most remote tuners are no more than 200 watt capability. Most likely because the size of the necess
Gee, if the roof is resonant on any band of interest, it might detune your antennas. Or it might make one antenna more directional than it already is. But, a roof mounted vertical would get the added
Yes, Hustler BTV antennas were made for the space cadet who doesn't believe that radials are necessary for a properly efficient vertical antenna. However, if an owner of a BTV goees to the DX Enginee

Roger My capacitor in my spare balun box is labeled " 56K NPO9KV " I also replaced the RFC with 2 each 250 uH chokes in series. It is normally 1 each 100 uH but a few times I accidentally tried to lo

Alex loosen it only enough to let a strong wind rotate the mast. In other words, snug. Then the braking system on the rotor will not get damaged. If you have a bolt in the rotor clamp, remove it so t
When Hurricanes Gloria and Bob hit Cape Cod, they stripped the leaves off the trees. In a month they grew back, just like having Spring twice in one year Best Regards Dan Schaaf K3ZXL www.k3zxl.com N
Roger I have had similar problems with SWR and I found that once a year, I have to remove all of the hardware, clean all metal surfaces that are joined by screws using a small wire brush, then puttin
Clint There were two different PCBoards in the RCS-4. The older version is open frame relay. The newer version is small enclosed relays just like those used in the DXE unit. You may only need to clea
That is really old. My OLD one has 3 relays open frame. I have no documentation on the 2 relay unit but I bet Ameritron will email it to you if you call them Best Regards Dan Schaaf K3ZXL www.k3zxl.c
Well, that is good news and a cheap fix. Maybe just disconnecting the coaxes and reconnecting them helped if they had a little corrosion on the connectors, the corrosion may have limited the DC contr
You may need a shunt inductor across the feedpoint maybe 3 to 5 uH to get the R-0 up I needed to do that on my short 160 vertical Best Regards Dan Schaaf K3ZXL www.k3zxl.com _________________________
ALso, X= 637 means that the antenna is short and the X is capacitive reactance. So you need base loading inductance in series from the coax center conductor to teh feed point. Then the SWR will come
What happens if you make the vertical as a cage of vertical wires around the tree ? Joined at the top and joined and fed at the bottom. The tree is in the center of the cage. Cage wire antennas seem

My take on this has always been, if the atmospheric noise can be heard in the radio, above the inherent radio noise ( with no antenna connected ) then you don't need a preamp. The preamp will amplify
Rick In addition to my IF DSP, I also have the Timewave DSP-599zx and it has AGC in addition to the noise reduction. It also has a CW Spotlight which makes the weak CW pop right out of the headphones
