The radio does not have power at the mic jack. So, yeah, you need to provide power somehow. I don't know that mic model, but if the PTT line is wired correctly, the radio should TX. When I had a 990, I isolated one of the two ground pins and applied voltage to feed the MD-100 I had, so I...

I looked at your schedule and saw the next broadcast is ...umm never. I wouldn;t mind listening to something that is in English, that isn't preaching or politics/propaganda. It would make SWL'ing useful again.

What does "doesn't let up at all" mean?

I'll PM you. SL

Sounds like self oscillation, if I understand your post correctly.

I wonder if it has anything to do with Marconi's passing. These two guys were THE antenna guys that brought me to this forum. Yes, there were a few others that had threads that were interesting, but these two were prolific. 73, SL

I believe it is 15%.

Radioddity appreciates the WWDX forum member brand loyalty. I have arranged a discount code, that can be used outside of other major sales events. I do test their radios, but receive no compensation from Radioddity. They are good people there, that stand behind what they sell, where others do...

It is the AT-5555N2 Short chassis QT-60 Pro

ON discontinued the part.

No change in bias. Added a cap.

I bought mine from mouser.

The service mode access key was changed in the current firmware version. The firmware in the video, is an older version, that is easier to access.

I have done this mod and it works. I am having good results with IRFZ24's replacing other FET's.

That's a great idea for a firmware update, if it is possible to manipulate the hardware to do this. I can't say I completely agree with you or Qixiang on this though. They don't warranty the radio, so once you buy it, you are dead to them. Why should they care if you toast your own radio?

If you don't have access to service mode, you can't do it. I have yet to see a radio from Qixiang off, out of the box.

Mine does 49 PEP on 25m. No complaints from me, especially when 10 and 12 are in the toilet and 15 is cracking!

I have used it quite a bit, for interconnects in repeater cabs.

Is the FQP13N10 now obsolete? I try to avoid using obsolete parts, it's hard to duplicate performance and reliability in the event the devices need replacing in the future.
