Hi everyone,
I just received my JumboSpot kit + RPI Zero, to change my old DVMega-Raspberry
Everything is configured, but the JumboSpot can't receive RF signal ...
I tried DMR, Dstar and C4FM.
Only C4FM (with FT70) seems to receive and transmit correctly.
But in DMR / Dstar, impossible to be received by the jumbospot. I'm going to check what's wrong with mmdvmcal.
On the JumboSpot board, RX offset and TX offset are indicated : 0
Results : No problem with mmdvmcal, my signal is correctly received in DMR (not tested with Dstar). By default my BER is below 2%
Probably a little offset of +100 to be optimal (BER 1.6%).
Everything seems to work with mmdvmcal, but why nothing is received in the dashboard ? A bug in pistar ?
Any idea on this problem ?
I check with a SDR (R820T on my PC) and both Jumbospot / Anytone D878UV seems to transmit on the same frequency
For the moment i'm stuck with this problem ...
Thanks for your suggestions !

Thanks for this information, i'm going to try
But the problem exist in DMR too ?
Edit :
Contain of the live log during a dstar transmit :

Re: Jumbospot : unable to RX RF signal
Off the top of my head -- it probably means your radio is configured for SIMPLEX operation, and hence is not sending the proper routing instructions in the packet header. You haven't identified what radio you have for D-STAR mode.

You're right
After a new programmation of Id51, it works.
I don't know why I need this specific configuration with the jumbospot, because on my old dvmega-rpi (with pi star 4), I don't need it...
So, concerning the jumbospot : dstar works now, as expected.
But nothing with DMR. Nothing in the live log. Just the RX led on the jmbo board...
For remind, no problem with BER according mmdvmcal
Any idea why pi star doesn't receive my DMR signal?
Thanks

Re: Jumbospot : unable to RX RF signal
Interesting -- since I created the snippets above using a DV-Mega R-Pi3b combination running Pi-Star 4.1.0
If "General Configuration" has "Node Type" PRIVATE, make very sure that the DMR ID in the configuration also matches that programmed into your radio.So, concerning the jumbospot : dstar works now, as expected.

Re: Jumbospot : unable to RX RF signal
This is the case : my D878UV have the same ID as my JumboSpot (and also my DVMega).
No live logs in DMR on my jumbospot
I'm going to compare the DMR / MMDVM settings between my DVMega (which is working) and the new JumboSpot

Re: Jumbospot : unable to RX RF signal
If you have both on-line at the same time, make sure the DMR configuration "DMR ESSID" has different values for the two systems.
