Analog FM mode working on MMDVM Repeater

Here is a quick demo of the FM Mode working on a MMDVM. I have some more fine tuning to do, but you can see that it does work.

V3F4 MMDVM board from BI7JTA

Could you show me how do you configure it to work FM Analog mode?

First FM mode doesnt work with a HOTSPOT board. For a REPEATER install you need to load the FM firmware onto ur MMDVM repeater board. All PROVIDING it supports it of course, as not all of them will.

You'll need to be running the current pistar 4.1.2

Then copy this into the mmdvm.ini file

[FM]
Enable=1
# Callsign=
CallsignSpeed=20
CallsignFrequency=1000
CallsignTime=10
CallsignHoldoff=0
CallsignHighLevel=50
CallsignLowLevel=20
CallsignAtStart=1
CallsignAtEnd=1
CallsignAtLatch=0
RFAck=K
ExtAck=N
AckSpeed=20
AckFrequency=1750
AckMinTime=4
AckDelay=1000
AckLevel=50
# Timeout=180
TimeoutLevel=80
CTCSSFrequency=88.4
CTCSSThreshold=30
CTCSSLevel=20
KerchunkTime=0
HangTime=7
UseCOS=1
COSInvert=0
RFAudioBoost=1
MaxDevLevel=90
ExtAudioBoost=1

I have a BI7JTA board, and the current firmware doesn't like FM

Could you provide. Link to the firmware you are using please?

Thanks

Well I can say that it definately works!

Having trouble getting the K (or I as i prefer), but the callsign at the end of the hang period is there

I've just put a license request in for a dual mode FM/DMR repeater (maybe the first MMDVM/P-Star FM unit in the UK?

One thing I have noticed is the acktime=1000. Is this milliseconds or seconds? Obviously if it's seconds, that's probably why I am not getting it

Thanks for all your help thus far!

I have a mmdvm pog i just updated the firmware and added the FM fuctions to the mmdvmhost file in pi-star and I cannot get the analog fm mode to work. Any help?

From personal experience, have a look at the settings in the mmdvm.ini file. If you don't have a COS connection between the radio and the board, set COS to 0.

Also, start pistar up and have a look through the log when it has had time to boot up and get all the services running. If you see anything involving a NAK relating to FM, then it will be more than likely a firmware issue, being incompatible with the mode.

Copy and paste your logfile, maybe we will be able to see something.

Hi

Wonder if you could forward me the firmware for the POG? I have an old pog board and keen to give it one last chance. Mine is dated 20190130. But I get NAK errors in the log for DMR.

Otherwise it BER for these two boards.
