Doug, You cannot get reasonable readings with the antenna on the ground. You can get more ball park readings by standing it on the back end with the front elements facing skyward. Suggest you place t

Howard, Lower mounting really has advantages for maintenance. I have a Prop pitch rotor mounted about 4 ft from ground level. I have 50 ft of 1 1/2" galvanized pipe that runs from the rotor up thru t
Arnie, Don't give up on the J-pole. Its a very effective antenna. I built one about 30 years ago and it's still in use. Mine is a tri-bander (146/223/440) I built it with copper water pipe (1 in. > 3

Don't sell the surplus military antenna switches short. Mine is a small 4 position rotary drum type fully enclosed. I have a homebrewed control box (24v) which now contains a Binary decoder interface
Be nice....This is a hobby! Where were you back in the 1950s when I worked 40M AM with a surplus ART-13 connected to the double bed springs and grounded to the bathroom water pipe?. I learned early o
Tim the MC-50 is a HI/LOW impedance Dynamic mic. I think the IC706 uses an Electrostatic mic. You probably will need a small preamp to make up the difference in Mic output. 73, Jim - w5ifp@gvtc.com _
Tim, The MFJ Antenna analyzers make good DIP meters. I have used my MFJ-269 as a Dip Meter several times. I prefer it to my Retro-Grid dip meter. Especially since the 269 has a built-in digital count
I do not use the MFJ coils with my MFJ-269. I fabricated simple 2-3 turn link coils of varying diameter attached to a short coax.. The dip will vary depending on the link coupling and circuit Q. 73,

Ron, I have used EZ-Rotor for several years in an old CDE controller, which is modified for my Pop Pitch rotor. The HAM IV is supported by Rotor EZ. The manual directional and brake paddles are still
I can vouch for the reliability of the Prop Pitch rotor system. I have used the same small PP rotor since late 1960's. I homebrewed a 500 ohm position feedback system using a modified CDE controller.
Erick, I have a Rotor-EZ in a CDE control box for my Prop Pitch rotor. The basic CDE controller is a very simple unit. Do you have the CDE manual? If the original components were retained, all you ne
