Re: CALIBRATION DATA
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".Fecskebeka wrote: ↑Wed Jun 16, 2021 9:39 pmOne radio in -W + mode only transmits with non-measurable transmission power. What could be the reason?

Re: CALIBRATION DATA
"--- 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.

Re: CALIBRATION DATA
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.

Re: CALIBRATION DATA
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
THX

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

DMR or FM audio? Those settings won't affect DMRvselic wrote: ↑Tue Feb 22, 2022 9:10 pmHm, im just curious, because i would like to upper the audio/volume gain output... so the station would be a little bit louder...
