Has anyone else had this problem?

After all the confusion of finding an understandable and useful manual (it was in the USB dongle that came in the box, I thought that was for firmware-only so never looked on it), I finally have exhausted all options and cannot get the radio to transmit a usable signal on VHF or UHF. I can hear the transmissions on an HT in the room, but no real output, and the ammeter on my power supply for it shows only a slight increase in power being drawn, maybe half an amp, no matter the "PA" setting . In addition, the receive sensitivity seems to be a lot lower on those bands, and the UHF has a constant pulse noise on the one frequency I want to tune it to, even if nobody is on it.

Has anyone else had this problem, or do I have a defective radio?

Or worse, did I transmit before knowing which output, (SMA or PL259) is the proper port, and blew the finals on VHF/UHF? That is a possibility, I agree!

,not connect.

Confusing, huh!

To make matters worse, the picture of the back of the radio in the 2.2 manual shows ANT1 as the SMA port, but on the real radio Q900 version 3 I got, that is labeled Ant2!

At any rate, neither output SO239 or SMA puts out any signal. I have the "FULL" version, with DMR, compass, GPS? modules added.

Have you checked your power settings? PA??

Bob: Your experiences and similar ones are the reasons this group exists. For me, the Manual 2.2 is deficient in many ways which I won’t mention here - well, just one: There is no mention of the FM Commercial Band Radio accessible from the Settings. It is excellent (entering a frequency manually requires “backspacing” o.1MHz) and I can’t figure out how to set the 5 “push button” settings at the bottom of the display.

I don’t have the DMR module and after watching the Chinese video on howto istall it, I probably will not try. But the Russian reviewer identifies your problem and mentions a workaround which I didn’t quite understand. You can read my translation posted In the Weblinks section (Topic).

I have a long list of deficiencies and corrections to Manual 2.2.

”So many things to do, so little time.”

Yes, I've tried that, thanks.

I would open up your radio and see if the connectors are still on. During shipping sometimes the wires are moved, there is no swr measurement on the vhf/uhf side on the radio so difficult to see if you have blown finals. If you do choose to open our radio watch the ribbon cables for the front panel they are very fragile. Hope that helps,

Thanks, Cory. I? looked yesterday? but don't have? a tiny? enough tweezers to open the ribbon cables! I will get some and try re-seating them later.

By the way, I? ran across this some time ago but? it got lost in the shuffle, and maybe someone else has? posted this video from a knowledgeable Russian, but may not have noticed? that you can translate into English:


Subtitles are in Russian, but you can set the gearwheel options to auto-translate into English subtitles.
