All,
I am looking to make our local 2-meter repeater a MIC-E capable system.
Currently I am using a MFJ-1270 (not for sure if it's a B) with the UI-DIGI
firmware. I was looking at the UI-DIGI documentation and it doesn't mention
it being capable of True-DCD which is needed to mute the repeater audio.
Does anybody know if the UI-DIGI firmware supports this or not? I've also
got a KPC-3 which is soon to be upgraded to a +. Which (if the UI-DIGI can
do it) would be easier to setup to be a MIC-E capable system? Thanks for
any info!

The evil ones sell a frame for this, 2x2 array, which I use in my ammo
cans. But we shall not speak their name here.

It's not a function of UI-Digi (or any other firmware) on a TNC2. The DCD
in a TNC2 is done in hardware (it's the lock indicator of the demodulator's
PLL system) and is independent of what firmware is being used.
The TNC2 "DCD" falses frequently on voice peaks -- just connect a TNC to a
radio on a voice channel and watch the yellow led flash randomly on voice
peaks and squelch crashes. This makes it virtually useless for Mic-E
repeater apps since it would keep muting holes in voice audio as well
during data bursts.
By contrast, the KPC3+ does do true DCD and doesn't false on voice energy.
If you truely want to mute the retransmission of Mic-E bursts at the
repeater, you will need to use the KPC3.

Roger,
Yes, the posits for the station I was testing this with have been first
send via the Igate. The be exact, Xatir sends its posit when I start it,
after that I tried the message to EMAIL.
Dick Stanich, KB7ZVA has made some changes to port 10155 on aprswest.net
wich made the messaging work. I don't know what he changed but it works
fine now.

Mark,
I'd be interested in sources for GPS engines at the $70. to $80. range.
Would you care to list some sources?
I have the Digitraveler and yes, took a bit of work getting the 6 volt
power...but not that much work <g> .
Thanks

The kpc3 does indeed work well at muting ONLY packets. It has an adjustable
delay (10ms increments) and must hear correct packet tones during that whole
delay. If you interrupt the COR line with the mute pin, you will hear a
short little snippet of a packet. If your repeater uses a voice delay
module, you won't hear any packet at all. Bob Bruninga has suggested using
a resistor to pull down the audio level instead of cutting the COR line.
His method allows the users to still hear the packet, just not as loud. I
prefer to not let the voice users know its there at all.

I just wrote power werks last week, and they are soon to carry P-Pole pins
which mount to a PCB instead of simply crimping on a wire. This will make
making power distribution on a PCB must easier (and cheaper) than the rig
runners. Rig runners are REALLY nice, but they are also REALLY expensive.
My daughter has one of those pink barbie jeeps which run on 12v. I put a PP
on it for recharging and in emergency, I'll use her battery to run my ham
gear. The mounting was accomplished with two little flat metal E clip the
evil ones sell.
