spectra vs ?
by Bryan D. Boyle 03 Aug '16

The Spectra, while a great radio for analog, and configurable like all get out (multiple heads, handsets, etc.), doesn't have a good place to pick up true discriminator (flat) audio with enough fidelity to drive the mmdvm. It was made for analog service, and their detection circuit just doesn't extract a good signal for digital use. Add to that the self-destructing capacitor issues on both the motherboard and display board (which will destroy the traces if left unrepaired), and the fact they're over 20 years old at this point...there are better (and not expensive) options. I've used, successfully with no more than 5 wires to the back connectors (flat rcv, gnd on the rx side, flat audio in, ptt, gnd on the tx side), both the GM300 and cdm750 radios both on allstar via a URI and digital through the mmdvm. Program for 25k bandwidth (let the sw handle bandwidth limiting, etc...don't put the hw in the way), if using the 300s, make sure the jumpers are set correctly on the board, program up with rss for the 300, CPS for the cdm, hook up and go. I do suggest, if you don't block TG 3100 on brandmeister, that you have a decent muffin fan blowing on the rear of the tx; because 3100 is almost constantly keyed up. measured the fin temps with the fan on, and with almost constant us, never gets more than 10 degrees F above room temps... Just for the heck of it, I did connect up an old hamtronics 440 machine I had that was on my freq, and even it worked, because it is a true discriminator rcv and the tx input is through a varactor right to the oscillator...not that I'd ever keep that in service, mind you... Just some thoughts. -- Bryan Sent from my iPhone 6S...No electrons were harmed in the sending of this message.

DMRlink and HBlink
by Robert Newberry 01 Aug '16

If I have it right HBlink is for the MMDVM crowd. What about someone in my situation running a TRBO repeater and DRMlink? I'm guessing nothing changes with regards to people running repeaters that are IPSC? Is HBlink going to be a way for us to mix mmdvm into our existing networks? I'm just trying to get a picture in my head as to how I will fit this into my "little network" which consist or Allstar analog repeaters and TRBO repeaters connected to DMRlink.

xreflector bridge software?
by Steve 01 Aug '16

01 Aug '16

Aside from the DMR gateway software, what other software is out there? I understand the xreflectors provide a way for D-Star / DMR and Fusion radios to cross communicate when everyone connects to an xreflector. Seems like xreflectors and the common CCS7 radio ID just needs an Asterisk tie in (or maybe it already does) Problem being seems a lot of the development is done by German hams, and there is a little language barrier to understanding what the xreflectors are running for software to enable all of this. Does anyone know more about what they are doing?
