[Freetel-codec2] Mixed mode UHF repeater

[Jeroen Vreeken]

Hi all,

Today the new repeater controller for the PI2EHV (Eindhoven, JO21qk)
70cm repeater worked in mixed mode for the first time.
It can receive analog FM (using CTCSS) and FreeDV 2400B and will
transmit analog FM.

The new controller on top of the repeater and IRLP node:

Wow that's great Jeroen - well done. I would be interested to hear some
off air 2400B signals if you get a chance to log any.

Cheers,

David

Hey, that sounds pretty cool. Is there code available somewhere for
this? Might forward it to the local repeater folks

Something like FM + FreeDV in, then two separate TX frequencies out (one
FM, one FreeDV) could be a great way to encourage adoption

The code is available.
The repeater runs 'freedv_eth' from my eth_ar project
(http://dmlinking.net/~pe1rxq/eth_ar.git/) coupled with dml_trx from
(http://dmlinking.net/~pe1rxq/dml.git/)

Currently having two outputs in that way is not supported, but it would
not be very hard to add it.

Hello Joroen,

Very cool and thanks for sharing! So is the DR1X in AMS mode so it
supports C4FM, analog FM, or what I assume is FreeDV2400B over analog
FM? Did you do anything special to the DR1X here? On the software
side, what are you running? BrandMiester? Svxlink? Something else?

The DR-1X is in base mode and fixed to FM in and out.
I would have liked to use AMS on the receiver (which would have made it
a tripple mode repeater) but the DR-1X logic just won't let me....
(Squelch signal drops the moment you touch the PTT in AMS mode which
make repeating very hard)

On the software side it is running my own software: DML (dmlinking.net).
The repeater is also connected to IRLP, but this is done via an external
box. (Just some extra audio in/out and ptt/cos logic)
I am looking if it would be hard to bridge echolink and DML, but since
that is all software will probably have to wait untill the repeater is
back at its home).
