[1000mp] SWR Problems with Mk-V Field

[carl at UDel.Edu]

I have a Mark-V Field hooked up to a G5RV and matched with a LDG AT200Pro autotuner.  I noticed the other day that my autotuner and my external watt-meter were claiming a 1:1 match, but the SWR meter on the Field was claiming 1.7:1.  While I don't expect everything to always read identical, I thought this rather strange.  I switched to a 50 ohm dummy-load, and did some investigating using the dummy-load:

160m - 1.1:1
80m - 1.1:1
40m - 1.0:1
20m - 1.3:1
17m - 1.4:1
15m - 1.4:1
12m - 1.4:1
10m - 1.3:1

All of these values were read from the SWR meter on the Mark-V Field; the autotuner and my external watt-meter/SWR meter are reading 1.0:1 on all bands  Might this be an indication of a problem, or have others noticed this discrepancy?  Any feedback would be most appreciated!


Thanks, and 73's!
