Re: Has anyone found the manuals yet?
James:?
These documents (Appendix 1 & 2, as I reecall, are useful in figuring how to enter your call sign and the canned messages for RTTY and CW. (I am strictly a CW ?op, so I can’t comment on SSB et al.) In my version, it is not possible to send an S or a Z, a problem for W9ZSJ. I think the firmware is looping based on the assumption that letters may be grouped in 3’s, as on an old telephone or celll phone KB. But, there are two buttons there which have 4 characters. The extras are - guess what - de W9ZSJ. I will be interested to see if the new release fixes this. |
Re: Q900 not transmitting on VHF/UHF
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.” |
Re: Has anyone found the manuals yet?
I think this is the version I have been working with and “rewriting” wen I find a nugget of information.?
I hope three is a better version. Barring that I hope that a Chinese manual may be obtained., preferably on line. Googol is pretty good at translating. I can’t believe that Chinese hams would tolerate the type of manual I have seen nor the absence of any written details. |
Q900 not transmitting on VHF/UHF
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! In addition, here are the instructions from the 2.2 manual re: antenna ports usage:
Optional DMR module 144MHz / 430MHz input and output from ANT1. Note:if optional DMR model. in 80 ~ 520 MHZ antenna 1, DMR and DFM mode for sending and
receiving antenna interface.Frequency in 80 ~ 520 MHZ model for SSB, the CW, AM, WFM, (NFM),
RTTY interface for TX.Antenna interface 2 in 100 KHZ ~ 80 MHZ frequency, mode for SSB, the CW,
AM, WFM, (NFM), RTTY for incoming and outgoing interfaces.Antenna receiving frequency range of
2 to 100 KHZ to 2000 MHZ.For radio inside two rf amplifier, share the different frequency band
signal amplification.So in 80 ~ 520 MHZ SSB, the CW, AM, WFM, (NFM), RTTY modulation mode, the
antenna interface 1 as launch interface, 2 as receiving antenna interface interface, need to pick up
two antennas at the same time.
No optional DMR model
,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. -- Bob, KL7EAL Los Angeles |

That’s brilliant. Thanks James.

Re: Just purchased a Q900 from ebay (shudder)
I have been on the WhatsApp channel for two days and got most of my answers within an hour! I don't know how to invite people or get the link, but? I got it from a scan from my dealer on eBay, fineshop. Here is what I scanned it from, I don't know if it will show here as it's an image:

Re: Has anyone found the manuals yet?
I think they meant the USB stick (or dongle).that you get in the box. But mine does.not.have the manual On Wed, Mar 8, 2023, 13:58 <dg8yhh@...> wrote: copied from my stick :-) |
