I installed DM-5R file.... what's the difference with the RD-5R .sgl?

I am not able to change anything in the Options menus, like "Options", "Display Options", "Sound Options"

73!
The DM-5R file got renamed to the RD-5R, to save confusion of users with the old DM-5R which was an completely different radio.

FlashLight is working already

I think it’s on SK2 + 6

After uploading the Open RD-5R software with the factory calibration settings, the radio power in positions 1W and 5W for VHF 8.5W and 9.3W respectively, and for UHF 6.5W and 5.3W. Measurements taken naturally at FM.

WOW.



Its strange the 1W and 5W values are wrong, as these are taken directly from the calibration

Can you reload the official firmware and check what power it outputs for Low (1W) and High (5W) settings.

Then your radio to one frequency on UHF e.g. 435Mhz and then measure the power output for all the values from 50mW to 5W.
Then do the same for UHF on 145Mhz

Then post your calibration data backup and also those values to the forum, and I will try to calculate the control factors needed to ensure the correct output power.

Also. Tell me what frequencies you used on VHF and UHF, because I need to see the values in the calibration data associated with those frequencies.

Measurement results made with the original firmware 2.1.6 at 145 and 435MHz respectively - low power 2.4W and 2.6W and high power 5.1W and 5.4W. The image of calibration data is attached. In the next email the data after uploading the OpenRD-5R software.

Hi, after reading this message I was intrigued and I tried it too. These are the results on my RD-5R:

145,500 Mhz 5W on the display -> 7 W
4W -> 7 W
3 W -> 7 W
2 W -> 7W
1 W -> 7 W
750 mW -> 6W
500 mW -> 5 W
250 mW -> 4 W
50 mW -> 1,8 W

430,300 Mhz 5W -> 4 W
4W -> 4W
3 W -> 4W
2 W -> 4,2 W
1W -> 5W
750 mW -> 5W
500 mW -> 3,5 W
250 mW -> 1,5 W
50 mW -> 0,9 W

435,000 Mhz 5W -> 3,8 W
4 W -> 3,8 W
3W -> 3,8 W
2W -> 3,8 W
1W -> 4,5 W
750 mW -> 4 W
500 mW -> 3W
250 mW -> 1W
50 mW -> 0,4 W



I can't attach the calibration screenshots

Ciao, 73 e grazie

@IU3LZP does the power calibration values are in the same ballpark as in the post from SO5AJG ?


Cheers.

Measurements after uploading the OpenRD-5R software made at 145MHz and power settings from 50,250,500,750mW, 1,2,3,4,5W - results: 2.5; 3.3; 5.2; 7.1; 8.2; 8.9; 8.8; 8.8; 8,8W.
At 435MHz, respectively - 1.5; 2.6; 4.6; 5.7; 5.7; 4.7; 4.7; 4.7; 4,7W.
I will send the screenshots in the next e-mail, because I can't now, because I have supposedly used the limit of attachments sent.

The fw seems to work very well on my RD5R and here is a video i did last night of our club DMR Net .
