Basically this corrects the transmit (TX) and receive (RX) frequency of the board, if they’re not on frequency. This is the BER 0.4% when no setting RX/TX offset.and a MMDVM board is a digital only device. on the flip side you can use AllStar on GMRS to link repeaters together and I suppose simplex nodes as well (no repeaters allowed on MURS) there is plenty of GMRS linking going on via AllStar. but you must run it on a private network as you cant cross GMRS and Amateur services.Repeater still works locally with no problem at all on the TG9 group. More importantly - restarting the repeater is fine - after the restart it works locally with no problem on TG9! I have not tested the WiFi option yet, but it looks like as long as the MMDVM board gets the IP address assigned, the system works fine locally on TG9!

One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola). This is a large and very visible forum.
