The second option is to swap out the D-Star hardware with an MMDVM repeater setup in D-Star mode. Of the 2 option, this is probably the best because it would allow people to change reflectors and even use the other reflector types, not just the old REFxxxx reflectors. Also, it would eliminate the convoluted hardcoded network configuration that ...Hello. My name is Kevin and I am attempting to set up a dmr repeater using your mmdvm repeater kit board and a kenwood TKR-850. I am having problems with the transmit drive level. Even with the TX pot full open and levels set to %100 in mmdvmcal, I cannot get enough drive to suppress the carrier. Do you have any recommendations?

Apr 11, 2017. Messages. 20. Apr 25, 2021. #6. I use MMDVM's for my multimode repeaters. One is a STM-32DVM connected to a TKR-850, and the other is the same MMDVM connected to two Kenwood TK-8180's. They function like a normal repeater, but DMR, Dstar, NXDN, YSF, and P25. The one with the TKR does both digital and analog.
This repeater is located at the 911 Center near Greensburg and currently has a power output of 20 watts. It consists of a Yaesu repeater controlled by an MMDVM board allowing it to operate as a multi-mode digital repeater accommodating FM retransmissions as well.Green Bay, WI. Feb 27, 2022. #2. You are correct. All the modulation for the various digital modes is done in software. So all you need are flat audio connections to analog radios to create a capable repeater. And yes you can use MMDVM without any internet connectivity. Side note, you'll find calibation for the DMR mode is the most finicky.Pi-start is a way to make a MMDVM (available from Newegg and other retailers) a DMR digital repeater node to talk with digital radio.

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.Specifications.

MMDVM in general works very well with all kind of DMR radios, but could have (unexpected) problems with some particular combination of radios. With Guillaume VA2NA reports, we learned that Motorola radios are very sensitive with audio sequences losses, produces big silences, and that doesn't happen with other radios.
From: [email protected] <[email protected]> On Behalf Of John Sent: Tuesday, October 20, 2020 1:10 AM To: [email protected] Subject: [repeater-builder] Motorola MTR-2000 with MMDVM Card from WA0EDA Design I'm hoping that I can find someone who can shed some light on this issue. We have a MTR2000 with the add-in MMDVM card as designed by Cort Buffington. 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. 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.In today’s fast-paced world, staying ahead of the curve is crucial.
