OpenGD77

One radio in -W + mode only transmits with non-measurable transmission power. What could be the reason?
<0.1 ?? no measurement is indicated on the meter, but there is a receivable transmission on another radio.
If I raised the 1W setting to 200 a cal. table, smaller power signal also appeared measurably

The "+W-" power level is defined by a user setting (DAC value): "Options" -> "User Power".

"--- The" + W- "power level is defined by a user setting (DAC value):" Options "->" User Power ".---"

Oh yeah.
This solved the +W- problem. I set 500 earlier. That's why TX really fell. Maybe I did this one night. Sorry, I don't remember and didn't have a power meter before.

Thank you Daniel!

I was excited, something is not good on the radio.
Now 4100 -> 6.1W

ZS.

Hi,

In VHF you can have more than 5W, but it's discouraged to use such high power level, you can damage your radio.


Cheers.

Thanks!
I don't use that much power!
UHF 500mW That's why I want to set it up properly

Ok ... sometimes bigger, if necessary

Hello,

Does anybody know, what means in calibration cps:
If gain (rx course and fine)
Audio Gain (rx course nad fine)
Recieve agc target
?

These settings were discovered by VK7ZJA, only he knows their exact function

They should not be adjusted

Hm, im just curious, because i would like to upper the audio/volume gain output... so the station would be a little bit louder...

DMR or FM audio? Those settings won't affect DMR

BTW.
