Tnx Much Toll Free... I adjusted VR 7 which is the balance modulator and No go... Still there...
I guess I will have to send it out to have it further diagnosed, It's definitely beyond my scope of know-how...
Thanks again for the input!
On my 2950DX I have detected a slight carrier not even detectable by a good watt meter... VR7 has been adjusted for minimum Spurious emission...
Question now is... Is the carrier due to a Biasing problem... The radio sounds great on SSB ... But would like to get rid of the little bit of...
After much discussion on High Power Solid state equipment... I always go back to this amp and wonder if anyone has used one...
They look like their built like a tank I'll tell ya...
QRO 2500 ... One Nice Tube Amp...
It's hard with old sweep tubes but I would stay with the same # for tube, and always best to have matched tubes when buying...
Obviously for sweep tubes this has become impossible... My self have encountered problems with mixing and matching, Different tubes are built slightly different and...

Within the next 5 days I may have a potential new toy on the way and was wondering if anyone knew the conversion for 11 meters.. Whether it was just a crystal insert OR if there was something else that more directly needed to be done.
Thanks much.
Not really a waste here under 50 miles.... We have so many hills and valleys it's tough to work decent with a vertical.
I have a guy here that gives me a solid 2-3 S-Units better than his vertical... He's a little over 20 miles away... With the beam nice and clear with no Pre-amp.... With the...
No doubt about that.... I was reading some posts on eham.net and the reviews it got were amazing... Alot of people had some very nice things to say about the amplifier...
Of all the products on eham I think this one had one of the nicest ratings of all for all the posts they had on there...
