Hi,
When I opload fw 4.3.4 my eeprom does not hold information.
Every time I start the Q900 up there is a message :?
EEPROM Load configuration failed!.
I uploaded fw 4.3.2 again and the set works fine again.
Do I something wrong or is there a problem in the fw?
73s. Kees PA0KME

Trouble with TX on SSB seems very common in this radio. When I listened to my audio I thought the final stage has too little quiescent current. Pretty hard to adjust as there are no trimpots on the pcb.?
|
Correct, it boots and is stable.?
That said: While testing power settings on two different radio sets (TBR-119), the power settings on 2M and 70cm are all over the place. One radio the above bands and mode are very low powered. 1W in low power, 6-3W in high power respectively.?
Also the power settings on one radio do not change anything. It transmits at 20w in those bands on NFM regardless of modifications to those power settings. Low power, high power, different increments within this, nothing changes.?
HF was better on the low powered radio. Around 20w.? Haven’t tested HF power yet on the second radio.?

For many of us it doesn’t even take that much. It just doesn’t boot

Radioddity QR20 Firmware Upgrade
I was wondering if anyone on this group could help me out with getting my QR20 upgraded.? It is showing HW: v2.0, SW: v2.0.1 and I would like to get it to one of the newer version 3 firmware versions, but I am finding some conflicting information out there.
1. I asked Radioddity support, they said "the QR20 with V2 hardware cannot be updated to V3 firmware since there is a hardware difference. We recommend not upgrading to avoid damage to the radio."
2. On the Radioddity web site they have a PDF with instructions that indicate you need to "Disconnet the UV amplifier power cords" and use "Dfuse Demo software" to do the upgrade via USB.
3.? In this forum post on linuxslate.com it says "Q900 Radios that show HW: 2.0 (or later, presumably) can be updated using a USB Flash Drive. Installing a separate Bootloader file is unnecessary at this time."
I was just wondering if anyone here has done the upgrade either by desoldering the U/V amplifier or just using the flash drive and skipping dfuse altogether. I'd like to get the firmware upgraded but I'm not familiar with the rig and I would rather not brick it.
I appreciate any help you can give!

Would you have more detailed photos of the DMR?
and GPS it can also be easy to put another module in place
|
Could you post photos of the DMR board up close with details of the components?

Re: The firmware for PMR-171 is wanted
Hi!
Interesting to know, because the PMR-171 is mentioned in clear txt in the firmware 3.4.1 for the Q900...
But it will boot and work without the encoder? That would mean that the PMR firmware could work with the Q900 as I was wondering. I just posted the idea to try to connect the PMR mit to the Q900 since the same mic socket is inside on the mainboard of the Q900.

Hi Damon,
You have the PRM-171 probably closed by now, but I would like to know if the pins from the mic socket on the mainboard go one to one to the mic socket on front. And also wich two pins are not used. The socket on the mainboard and the cable have 8 pins/wires, the mic socket has only 6 pins.
I'm wonderung if the PMR mic (MH-48 clone) could work on the Q900 since it has the same socket on the mainboard. In firmware 3.4.1 I can even find a clear text entry with all variants including PMR-171.
But then it could also be, that the port is disabled when the Q900 is recognized by the firmware. Would be intersting to try though.

The firmware for PMR-171 is wanted
Hi.
Does anyone have a firmware for PMR-171?
Not on the manufacturer's website.
The firmware from the Q900 does not fit (the valcoder does not work).
|
'callmeglib'
I have 2 Q900's and a PMR-171.?
The PMR -171 is a Q900V4 inside with only minor changes to the faceplate and of course the chassis and power.?
The GPS (w/GSM) and compass modules are very simple to insert on the internal headers coming off the board.
The DMR module, however, takes some careful soldering of about 30 scallop contacts right on top of the board just 2 centimeters away from the main processor.
I've attached photos for your edification.?
?The middle photo is an angled photo of the GPS module (seen in the left-middle of the photo). Once you open it up it's very?easy?to install.

Hello,
Does anyone have, or would be willing to take photos of the internals? I have a PMR-171 (group is new, not active yet), and I'm installing DMR, GPS and Compass modules. I've asked Guohedz for documentation, but they have yet to come through for me.
As these radios are extremely similar, I was hoping maybe someone already had pictures of the internals with the modules in place.?
Thanks!

Anywho…. I believe most of the upper VHF/UHF WFM/NFM drama started with 3.4.x versions. They were attempting to resolve some TX power and modulation issues and things just went sideways from there.?
I have had similar issues with the support people. I made a video describing my ‘not-pleasant’ recent experience with the radio.

Regardless, I talked to GH support two days ago and they said that they are (hopefully) about 2 weeks out on a new binary release and prayerfully expect that will fix a bunch of issues.?

Hi Kai, Like you I went after the mic audio first. My use for this radio is much different than most it would appear. I’m looking for one bug out radio that will receive everything. The fact that it transmits is a real plus. I want small, light and no frills that can be deployed and run off any voltage source regardless of voltage. This is it if it worked. So I chose the small cheaper mic because it is simple, light and small. Upon taking it apart I found that it was an electric cartridge, good. But it was to small for the mold hole in the mic and with no hole for the audio to get in. No padding at all leads to the audio having to go through the speaker grill and wander around until it finds it’s way into the echo chamber with the mic element. I replaced the mic with a Motorola mic that was the correct size but the Leeds did not match up perfect so some adjustments were made to the housing. I drilled a hole in the mic so audio could reach the mic and lined it all with felt. I don’t think replacing the mic is necessary as the problem was the echo chamber it was in. I further put a variable resister across their swamping resister so I could adjust the gain of the electric mic. Mic sensitivity if you will. This made the mic sound pretty good! No money spent! I also cut the internal speaker loose and removed making it even lighter. Now I had a good sounding cheap, light mic.? Looking at the SSB wave form on the oscilloscope showed that the out put of the radio was cutting the center line and flat topping! Tried adjusting everything I could to no avail. I decreased the cartridge gain, in the mic, until I had a perfect wave form! Then looked at the watt meter. Hardly any power out. As soon as I increased the mic level it would flat top. A check of AM/FM and they were very low and unusable. Back to SSB. The circuit that controls this is the ALC, automatic level control. I did update the firmware? Could that have caused the ALC to not work? That was the big problem with the last two I bought. I probably have notes on what was wrong with the first one. So I returned them and ordered another one. Been waiting almost a month and the due date came and went. I inquired about it being late and started a storm? They refunded my money and said I cause much trouble for store? I just wanted to know if everything was ok? They now don’t know where it is but said I could still buy if it showed up someplace? WOW!! I’m waiting for someone to say,” hey bone head did you check the……..?” Thank you for input. I have a pair of G90’s that work pretty good. Other issues there but are useable. Great tuner and easy to use but no VHF. That is where most public safety is. So then need a second radio to monitor them. Back to square one.

I tested again this evening. The gain setting did work with SSB on VHF. I started with the same setting as it was on the recording. There I got the feedback that there is overdrive. After reducing the gain, the overdrive was gone and audio was good. I did not test the cmp setting. I plan to get an USB SDR receiver. Then I can do some more testing and listen to the signal myself and record it. I have no other HF/SSB receiver. The test was done with my self made amplified mic though. What microphone are you using? I did a comparison with the original mic and my amp mic on VHF WFM yesterday. Even at same gain setting and the output of my amp mic adjusted to get the same volume, the original mic had some kind of cracking noises in the transmition while it was clean audio with my amp mic. I suspect that the Q900 does only work well with an amplified mic at this point. I have V4 with firmware 3.4.1
