Hi Paul, It's just a matter of adjusting the SensorCal menu setting until the power reads the same as the device used for the calibration. Of course, that assumes the calibration device is more accurate than the P3. :=) The nominal calibration value is 500. The intent was to make it corre

Alan - is there any documentation available on the procedure for calibrating the Tx Monitor? 73Paul __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecra

Yes, it can be calibrated in a manner similar to the W2. The menu entry is TXMonMenu/SensorCal. There is a separate calibration stored for each sensor type (200W/2000W, HF/VHF). Alan N1AL On 03/06/2017 08:26 AM, paul ecker via Elecraft wrote: A related question on this subject concerning t

A related question on this subject concerning the Tx Monitor. In terms of Power & SWR readings, can the Transmit Monitor be calibrated ? Or have other users found no need to adjust readings right out of the box? Reviewing the P3 manual on pages 34-35 there isn't much said about this subject. 73P

This is one of my pet peeves with the W2 -- it does not have an option for delivered power. Yes, I know how to subtract, but it's beyond trivial to do this in the software, and it would be convenient. Vic 4X6GP > On 6 Mar 2017, at 05:32, Alan Bloom wrote: > > The P3 shows total forward power.

The P3 shows total forward power. The power delivered to the feedline is forward minus reflected. With a 13:1 SWR, 73.5% of the power is reflected and 26.5% is transmitted. If the transmitted power is 92 watts then the total forward power should be 347 watts. Alan N1AL On 03/05/2017 06:5

I placed the DCHF-200 after my antenna tuner. In other words, the DCHF-200 is between my tuner and antenna. When relying on my tuner to match the antenna to the radio My power meter (on the P3) is showing an SWR of a little over 13:1 (which is about right) . My meter on my tuner is showing ab
