I have this cheap set and they are really good. It even came in a nice little box. You can make your own, but this is great value for money IMO.

Exactly this. A few FC tips:
You can often get by with adding a coupling capacitor, like a 100pf on the end of your random cliplead to reduce the loading on the circuit you are measuring. It still will load the circuit you are measuring, but not as much and might get you out of trouble.
You...
The 7900v doesn't have the jumper and associated components installed on the PCB. As mentioned by @Eldorado828 the 7900v is band selectable via its firmware, while the AT-5555Nii is selected via the installed hardware jumper.

Insertion loss can be a big deal, and when a relay is dirty/bad, that loss increases significantly. Some can be cleaned, some you just replace.
As an example, only -1dB of insertion and cable loss (a "typical" example dB loss you might see in a regular radio/ham shack), assuming a 100W TX...
Your setup sounds good to me. It's a strange issue, and I have not seen this on any of mine before. Sorry I don't know what else to suggest. Maybe your radio has a component that is out of tolerance, which would be bad luck more than anything else. Good luck with it, I hope you can work it out!

That's unusual. Slight changes can happen, but 1.3 to 2.2w is big delta for this radio. A couple of things to check to rule out the radio:
-Are you testing this into a dummy load, or an antenna?
-What power meter are you using?
-Does the result change with temperature?
-Are power supply...
That is not a common problem. It is unlikely to be a firmware issue, (but it is not impossible).
Have you been using an aftermarket mic on this radio?
FYI, the BOOT menu is only for loading new firmware. Entering than mode wont do anything to help you unfortunately.
Assuming you are in 26...
I agree 100%.
FWIW, below is as an example of some "cheap" but brand-new equipment you could buy, which could get you going. But even this cheap brand-new stuff, will still cost much more than your budget - and is absolutely NOT what I would recommend if you are really serious. (You would end...
I have a few of these, and the older generations of them as well. They are amazing fun, DX can be had with a whip antenna, however the SSB performance is very average (especially on the "newer" generation radios). They are all dated and compromised designs.
We really need a "new school"...
If you want a handheld with AM/FM/SSB (like a heap of us do) then I suggest sending an email to Anytone/Qixiang to let them know. They are interested, and could do with more market feedback to make it a reality. Let them know guys!

The first thing I do on all of my HF radios and CB's, is align the S9 value back to -73dBm. I will never understand why a large part of the CB radio world wants to see -67dBm. But to each their own.
Here is a good reference for anyone that is interested...
They have had my list for well over a year. Good to see they are getting similar input from multiple people. As for some of the things you say require hardware, don't be so sure! There are some tricks available on this PCB that can be leveraged in software alone (user FM Dev (not W/N RX filters)...
My wishlist:
Firmware:
-No VFO / CH change muting
-Expanded WX band 140-170MHz
-CTCSS tone frequency display, not CTCSS number) - e.g. show "118.8hz" rather than "16")
-2K / 4K FM deviation menu options
-TX and RX BPF settings. Allow upper and lower passband filter adjustments in main menu...
FYI, The latest IJV firmware for the Quansheng UV-K5 series handhelds, supports DSB RX and TX. It is a lot of fun checking into 2m SSB (USB) nets on a $30 HT. It works surprisingly well. 2m SSB is pretty popular here in VK land, so it's actually useful. (DSB to SSB "cross-mode" QSO's work...
Interesting, and all good on the RX. I wouldn't trust that old modulation meter though! (I think many old-school modulation meters would be better named "distortion meters"!)
Out of the box, the QT40 is between 80-90% AM modulation, and 100% is achievable with alignment (see my post up the page...
When you say "outperforming in every way", do you mean specifically the power output, and AM modulation percentage? Because that is the only two things that the 6666 has over the ARES2/QT40, in terms of "performance" that I have measured in all my testing. I know, those two things matter a lot...
