[Elecraft] K2 encoder installation 2018

The encoder plus attached PC board is attached to the Front Panel with a lock washer and 1/2" hex nut on the encoder shaft. The diameter of the hole on my Front Panel was 10 mm as measured with my calipers. The diameter of the threaded mount on the encoder is ~ 9 mm while the diameter of the ring

[Elecraft] K3 KIO3 board needed

Does anyone happen to have the K3 model KIO3 circuit card that is excess to their needs? If you have upgraded to the new K3S KIO3B you may have one. It seems that the RS232 control on one of my K3 XCVRs has bit the dust. I checked with Elecraft and they no longer have any of the old style.

You might want to add a common mode choke. Look here : http://www.dg0sa.de/balun1zu4kleinptfe.pdf It is in german, but the pictures show how easy it is to do. First, the choke is shown. The second core is the 4:1 transformer which you already have. FT 140-43 cores will do. For higher power,

If I were to sell my rigs, I think I would go back and look at some previous successful sales, and figure out the range of percentages of the new price that they were asking. Then I would calculate the new price of my rigs and apply a percentage somewhere in that historical range. Dave

[Elecraft] KAT500 Key Line Interrupt when in BYP mode?

When the KAT500 is powered on but in the Bypass mode will it still open the key line to the KPA500 at the preset level (3.0:1 in my case) if the load suddenly goes above 3:1? The situation is a remote autotuner connected to a 33’ vertical that I use for bands that I do not have a resonant

Re: [Elecraft] K2 encoder installation 2018

Ted, I am afraid you have ruined the front panel metalwork. The best solution is to purchase new Front Panel metalwork. Enlarge the hole for the threaded part of the encoder just a bit. I use a thin knife blade and 3 or 4 passes with it inside the encoder hole will do the job nicely. The

Gwen, First of all, a T200-2 is an iron core toroid, not ferrite, and is not likely to prevent much RF noise coupling. Any ferrite core will have an FTxxx diameter designation with two digits after the hyphen. That W3EDP antenna is a strong suspect, as is any off-center fed antenna or end

Ted, 1. The nut and washer go on the "outside", that is, the front facing side of the front panel behind the main VFO knob. The encoder shaft has to be fully seated on the inside of the front panel with the encoder shaft extending a good distance out, then tighten the nut and washer on the

Re: [Elecraft] KAT500 Key Line Interrupt when in BYP mode?

The value of SWR doesn't really inform us about the load impedance, line current or line voltage conditions existing. In the case of a 1.5:1 SWR, the load Z is 75 ohms, with a power of 500 watts the line current is 2.58 amps with a voltage of 193.6 volts. At the same time a 1.5:1 SWR, the

[Elecraft] KAT500 Key Line Interrupt when in BYP mode?

"The Elecraft KPA500 amplifier also works efficiently into a load SWR of 1.5:1" Any such claim is at best misleading. There may be some 1.5:1 loads that that the KPA500 will be happy with but there are other 1.5:1 loads that it will object to, to the point of giving multiple PA DISS faults.

[Elecraft] Data transmission on 30 meters with PX3 problem

As Jim K9YC has pointed out in his writeup on baluns etc, there is a threshold effect when one applies a choke to reduce common mode current. The current is determined by driving voltage and total (complex) series impedance. The choke RF impedance will have a reactive as well as a resistive

Re: [Elecraft] KAT500 Key Line Interrupt when in BYP mode?

Dave, yes my question was “do the VSWR Thresholds work when the KAT500 is in the Bypass mode” and the answer was No, they do not. There are workarounds of course but the question was specifically when the KAT500 had been placed in the Bypass mode with the front panel button. The manual did
