[Elecraft] K144XV Strange Readings

[Michael Eberle]

I have the same problem even running it with an amp.  I wondered if maybe somehow some of the 10M IF was coming through causing the meter to show SWR.  But during modulation, the higher power 2 meter signal caused the meter to display correctly.

Mike - yes, I've seen the same thing. I can't put my finger on it either but when using the k144xv with my wattmeter, I have high SWR always. Normally I can still run the 5-7 watts into an amp without issues but there are times this high SWR trips things off.

Elecraft - it would be nice to finally understand what needs to be done to correct this issues. Very common among the users that are on SSB/CW, not so much FM.
