Re: 7000DLE MkII PA temp overcompensation?

Perhaps your title should read "undercompensation"? Maybe? Since the PA gain will normally increase with temperature, overshooting the stabilization isn't "over" compensation? I'll ponder that when I'm more awake. And you're correct about it being less than 1dB. Characterizing t...

7000DLE MkII PA temp overcompensation?

My 7000DLE MkII (big silver box version with no PC) has an interesting, if minor issue and I'm curious if anyone else has seen it. The PA bias compensation appears to be over-compensated: (1) Boot the rig from ambient (cold) (2) Quickly set the PA calibration [for some band] so that the output power...

Re: Unstable, wide, nasty spur

Yep, it’s 10uA, so 140K. Thanks for the catch.
I even misstated the units. Go me.

I don’t have the 7000DLE (Orion?) drawings or schematics, so I’ll see if Apache Labs will send them. I thought I had them, but that’s the one full-power rig I haven’t owned.

Re: Unstable, wide, nasty spur

OK, let's see if this works: If I move the LTM4628 switch freq to 580 kHz, it keeps the spur out of the US ham bands until you get to 10M. If I remember correctly, the spur level by the time you get to 10M is low enough that while you can see it, it doesn't interfere with normal operation into a liv...

Thanks, Scott. I have Kapton tape and a hot air station. Now whether that resistor is in a low enough density area of the PCA that I’d feel comfortable messing with it remains to be seen. He has an original 7000 as well, which is as much fun as the older rigs to tear down and re-assemble. It’s worth...

Re: Unstable, wide, nasty spur

Has anyone managed to move the spur or dampen it? A local bought a 7000 and on 160M and 75M the spur lands on inconvenient frequencies, and the level is well above his receiver noise floor. What I'm wonder is if there's an inductor or something that could be persuaded to drag the SMPS off it's "...

Re: Space bar MOX causes TX audio garbage?

I can not begin to fathom how the method of PTT could possibly affect your audio in any way. I can't either. What *appears* to be happening is that pressing the space bar is causing some PowerSDR thread to stutter. Why or how I don't know. If I have time this weekend I'll un-install PowerSDR, remov...

Actually I haven't tried the headphone jack yet, just the rear-panel jacks.
I'll think about that. The impedance is all wrong, but as long as the audio amp doesn't care about that it might be worth trying.
