Re: [Elecraft] {OT} - Variation on use of a coaxial switch (stan levandowski)

Years ago, I built such a switch to prevent accidents should one radio transmit when comparing two radios. It is basically an a/b switch such that a radio became the active radio by switching the antenna to it, and simultaneously switching the dummy load to the inactive radio. Neither radio is

Re: [Elecraft] Need help from an EZNec user on a horizontal loop question

My current antenna is an Inverted L 1/2 wavelength long at 80 meters and is direct fed. That length puts the voltage "loop" (maximum) at the rig, so the counterpoise requirements are minimal on 80. The L is 40 feet vertical and 80 feed horizontal. That puts the current max near the bend on the

Terry, Have you considered an 80 meter inverted L? It takes up little real estate for the radiator, but does require putting down a ground screen at the base of the inverted L. If you do not wish to bury 32 radials for a ground screen, consider using resonant elevated radials. Two elevated

Re: [Elecraft] Need help from an EZNec user on a horizontal loop question

While you design and experiment with a new loop: Install a reduced size dipole for 80. My rule of thumb, which has worked for many quickie antennas is to use insulated #14 wire and close-wind on a 2" white PVC pipe a length of wire that is twice the length of that removed from the antenna.

Re: [Elecraft] MH3 mic with the K3?

Ron, No. Pin 6 is NOT bias, but a source of 8 volts. Bias to the microphone is applied through a resistor, not directly from a voltage source. All you need to do is turn BIAS on in the MIC SEL menu. See the K3 manual for the button to tap to toggle the bias setting. 73, Don W3FPR On

Re: [Elecraft] {OT} - Variation on use of a coaxial switch (stan levandowski)

I've also have thought about running a switch so I can switch between a couple of radios here (and a way to idiot proof it). I have considered building up something using relays (or a manual switch) that would switch each radio into either a dummy load or into the antenna path. From:

Re: [Elecraft] {OT} - Variation on use of a coaxial switch (stan levandowski)

The isolation provided by this switch will be really poor. In addition to the capacitive coupling of the switch itself, note that only the center conductor is carried between inputs and outputs, so that the chassis carries return current. This adds a lot of inductance to the path, and causes
