DMRDelay is how you tell MMDVM about this delay so that the subscriber can properly synchronize to the repeater. It appears the XPR8400 has a similar receive architecture. I re-tested D-STAR and got the RX pots optimized. Then testing DMR, I started with DMRdelay of 165 and walked down to 1 55.MMDVM Repeater Board V3F4 for DMR C4FM/YSF,NXDN DSTAR POCSAG P25 MTR2000 GM340 GM350 GM360 GM3188/GM368 CM140 Yaesu ICOM Kenwood. 5.0 12 Reviews ౹ 50 sold.

This is a simple way to implement a combined analog and multi mode digital repeater using a Kenwood TKR-750/850 radio. A Zimmerman MMDVM Pi-Hat was used for our modem, but the idea has been implemented using other modems. A programming trick is utilized to allow the internal analog controller to be used on both Ver 1 and Ver 2 radios.

The hangtime is the amount of time the MMDVM will stay in that mode before allowing other digital mode signals a chance to reach the repeater. RF Hangtime is the amount of time the MMDVM waits after the end of an incoming RF (Radio Frequency) signal.Model: Pi-Zero with MMDVM hat Type: Digital Mobile Radio hotspot MSRP: Amazon $102.99 (Link is to the one I bought. I don't sell anything and don't receive kickbacks) TLDR - High technical demand with steep learning curve. But worth every bit of effort if not near a DMR repeater. I recently ventured into the world of DMR. GB7RA repeater is available on the following frequency. This repeater supports users of DStar & Yaesu System Fusion/ C4FM. It will allow you to connect using your preferred digital voice (DV) mode. If you use a particular mode please follow the rules of etiquette for that mode, but most of all enjoy using the repeater. The 878 has a ranging mode which will periodically check if you are in range of the repeater- if it doesn't get a "handshake" back it will tell you. In theory it's a nice feature but kind of annoying in reality. Since you said "I can hear the analog side" I'm assuming it's cheap MMDVM repeater, running in dual mode.If you want to start your own business, know the odds.
