[P3] P3 and K144XV

Does the P3 Display 2m with the K144XV and other XVTRs?

Re: [P3] P3 and K144XV

HI Bill,

Was there some set up you had to do to get the P3 to properly display
the spectrum when on 2m? I tried this last night to discover on mine
set up that the P3 spectrum display noise line climbs out of site and
the water fall goes to orange. Switch back to 6m or below and all works.
Same on both my K3s.

Does any one recognize this symptom?

Thanks and 73, tom

Re: [P3] P3 and K144XV

Tom,

Sounds like your "Ref Lvl" is set too high. The color of the waterfall reflects the vertical position of the trace in the frequency display. If you reduce the reference level, the frequency display will return to a viewable position, and the orange waterfall will revert to blue.

The reference level is per-band so you have to adjust it for each band you operate on. For my 2m setup the ref level is set at -145 dBm, which allows me to see the frequency trace when the pre-amp is on or off.

Re: [P3] P3 and K144XV

thanks Stan,

I tried that but will go back and try it again. Was planning to hook a
spectrum analyzer to the IF out to see what the actual output level is
when I switch to 2m.

Hi Stan,

Adjusting the ref level does not help. Looking at the IF output of the
P3 the actual signal level is not changing when I switch between 6m and
2m. I hooked up my QS1R SDR and can see the signals fine when the P3
water fall display is orange when I am on 2m. I can not find a ref level
that works. Radio is working fine on 2m as I can copy signals fine.

When i disconnect the serial cable between the P3 and K3 the display is
fine minus frequency and filter info of course.

All the software is up today. Both of my K3s do this.

Any ideas gang??

Re: [P3] P3 and K144XV

It could be that the MENU:XV_Gain setting for two meters got wildly
wrong somehow. You might try changing it. Another possibility would be
to do the parameter initialization (under Troubleshooting in the
manual).

Re: [P3] P3 and K144XV

Thanks Alan,

I will go back in and check the initial set up for the K144XV as well as
the P3 and K3. Certainly some sort of widely different gain setting on
2m. BUT looking at the IF out the signal levels are "proper" as I did
not have to change the scale very much on the SDR pan display.

Re: [P3] P3 and K144XV

OK, seem to have solved the problem. The P3 XV Gain #1 setting was way
wrong, in fact never set right. Also had to switch the P3 XV Invert #1
to inverted. So now appears that I can see the 2m spectrum with the P3.
Just have to go get a signal generator to calibrate the display.

Alan and Gary from Elecraft kept suggesting what to do until I got it
right. Thanks Alan and Gary and Elecraft.
