[Elecraft] P3 vs SDR-IQ

[dmb at lightstream.net]

Joe,

Are you by some chance using your P3 with the "FixTrack" mode set to
"Tracking mode" rather than "Fixed-tune mode"? If so,  WHY???  ;-)

I used PowerSDR with a FLEX-5000A for years and always hated that it ONLY
supported what Elecraft refers to as "Tracking" mode. Eventually, as
PowerSDR was completely reworked for HPSDR (and now ANAN) the "Fixed-tune
mode" was implemented and works well though it has a couple of minor bugs.
The new FLEX 6000 series SmartSDR uses "Fixed-tune mode" as well. I don't
know if it's even possible to get it to work in tracking mode -- I've
never tried, and have no idea why one would want it to.

Regarding the P3, I've been using the P3/P3SVGA with my K3 daily for about
3 1/2 years now in Fixed-tune mode, and have *never* seen any change in
the noise floor during tuning under any circumstances regardless of the
level of averaging used.

If you are seeing the noise floor change in any way while tuning in
"Fixed-tune" mode, then something is definitely wrong.

Best of luck in getting this resolved.
