Hello all, I would like to have PTT out signal from my K3 that is ONLY activated when the internal K144XV transverter is transmitting. I thought I might use the KRC2 with the K7MDL mod where the 8R signal is used to generate a band specific PTT output. The problem: where do I find an 8R or

While I use an external transverter with my K3S, I do not suggest using the K3 internal preamp.  The transverter has adequate gain and also a good low noise front end. 73 Bob, K4TAX On 6/5/2020 2:03 PM, Jim Miller wrote: Helping a friend to try to get the most out of his 2m equipped K3

Hello Graham, dear YLs and OMs, There is adjustment resistor inside the internal Transverter. Here only you will be able to maintain right power setting. I did this one time for all my transverters. Max power is for me 2,5W. With power (pwr) knob, I can maintain 1 to 2.5 W. Hope this helps

Re: [Elecraft] K3 with 2m tvtr - power control feature request

One more reason I forgot to mention. If your power output has to be adjusted every time you switch to the band using the transverter, sooner or later, you will forget. That might be the end of your transverter. That is why I always set my stuff up so I don’t have to make any adjustments when

Re: [Elecraft] K3 with 2m tvtr - power control feature request

Graham, You didn’t say which microwave transverter you are using. Perhaps the transverter input requirement can be adjusted to accept the 7W vs 5W. Many of us who drive transverters at reduced levels find that the driving rigs often have full power spikes for just a few milliseconds when

Graham, You say you have measured the input power to the K144XV and it is a max of 0dBm and a minimum of -7dBm. If that is incorrect, then my conclusion (following) is wrong. A difference of 7dB should produce 1/20 of the power developed at 0dBm - based on 10 watts output, you should

TJ, It may be right. But without your refcal values, can't say for sure. However, your results do seem to be lower than typical by a factor of 10. You may have missed a decimal point somewhere. i.e. a more expected offset would be 470 or 490 Hz, not the 47 or 49 you indicate. Check your math,
