"Hybrid" repeater which features both FM and D-Sta
Sounds interesting....
I talked to one of the guys getting it on the air and he states it has good coverage in analog mode so far, I haven't asked how they got it to run analog and D-star at the same time.
Just what I need, an excuse to buy another radio

Pass through repeater?? Not sure what he is doing with the Kenwood machine to make it D-STAR Hybrid???

Two maxtracs back to back, check out this thread http://batboard.batlabs.com/viewtopic.php?t=45645 over at batlabs.Mong wrote:ka8ypy wrote:Pass through repeater, when he is done with it, you should also be able to use it for P25 as well.
I guess that's my excure for a UHF XTS5000 to match the VHF one the way
Thanks for the info, do you know of any others that have worked that way?
Has all the info you need to "roll your own".

I remember reading that before, but was curious if that worked with the D-star stuff as well.

It should, D-Star is AMBE.grinthock wrote:No reason why it wouldn't once you adjusted the deviation properly.
The question is... Will the settings optimized for IMBE / P25 also work to pass the D-STAR as well...

It's not that simple... I know very little about D-STAR, and how it's modulated and what the waveforms look like, how it deviates, how the receivers are tuned...
It's quite possible it won't work.

Deviation is the same for both IMBE and AMBE, so if it is set for one, it should in theory work for the other.grinthock wrote:It's not that simple... I know very little about D-STAR, and how it's modulated and what the waveforms look like, how it deviates, how the receivers are tuned...

The voltage points are different between the two (I think, I have to go back to DVSI web site and read some more), hence one not working with the other directly.

The vocoder is largely irrelevant to whether the repeater will repeat it, unless it actually contains vocoding capability. The modulation, frame formats, FEC etc are what you need to worry about, and between P25 CAI, these are incompatible.
Sometimes you can get close enough for it to not matter, e.g. a repeater designed to repeat FED-STD-1023 will happily repeat SECURENET, because the systems are so similar, but you won't get that in this case.

We have such a ham repeater here (RX Motorola GM900 / TX Motorola GM950). It works in analog, in P25 and D-Star.
Of course a true digital repeater would be better, but for the price of this setup it performs quite well.
Well, I was playing fool on SSTV with another , and here is the result :)Mong wrote:Ok, thanks. BTW, WTF is up with your picture on QRZ?
That picture is quite old (done around 2002). I live in Poland now (Warsaw), my other call is SQ5AG and I've become a full-time Motosexual since that time
I have some P25 and D-Star equipment, so have a few of my friends. We decided to build a digital-capable repeater (Input: 431.300 / Output: 438.900). It allows us to do some side-by-side tests of these protocols (so far we discovered that P25 had a better error-correction system that D-Star).
Our current project is to build a D-Star VHF simplex - Analog UHF simplex patch, to allow D-Star users to discuss with those with analog equipment. A lot of fun in perspective!
What do you do to keep out QRM/QRN? Just wondering. I'd like to put up an IMBE capable repeater here and this would be the only way I could pull together the funds to do it but, I don't want to put something on the air that I can't keep from keying from intermod or malicious signals.f4ddp wrote:

You don't, unfortunately. The passthrough repeater does just that - it passes anything it hears on through.k4wtf wrote:What do you do to keep out QRM/QRN? Just wondering.

I had an idea to jerry-rig an IMBE COR circuit out of the BCi25 cards for the older BC780/235 scanners, but no one seems to have a schematic or pinout for the connector (with good reason, most likely. )

Yep, it's called "the kNACk." I haven't personally played with it, so YMMV.w4wtf wrote: I saw a software NAC decoder somewhere, perhaps that could be used to open squelch with a valid NAC if it is fast enough.
Read here..
OK. So a nice clean RF environment is important here.
What is your experience with yours? Does it TX a lot on garbage or is it OK?

On a similar note, has anyone connected two astro sabers in AVA's to make a repeater? I know tweaking the audio levels is very important,
I am thinking of trying 2 AS1's in AVA's using this software controller

Why do hammies feel the need to label their repeaters? Putting the callsign, input/output freqencies, and the pl on the front of the repeater is just gay. Nobody cares!

I thought that was a requirement at the larger shared sites, so if someone was having an interference issue they'd know where everyone else was TXing at, as well as who to contact if an offender was located.K8TEK wrote:Why do hammies feel the need to label their repeaters?

I haven't actually put one up. <_< We have an issue around here with broadband sweeping noise across the entire 430-450 range from what we're pretty sure is military radar, so I don't think one would fly too well (pun intended? ;p )k4wtf wrote:OK. So a nice clean RF environment is important here.

There's also the issue with re-clocking. A Quantar/Quantro reclocks its received signal so if there's any noise in it it's completely removed before retransmission. The passthrough repeater doesn't do that - it just repeats what it hears. So if you're marginal into it, you're still going to be marginal coming out of it.

It's like whenever you talks, nobody cares
How many hams are putting up digital/900/1200/900 with 6meter RX? Some people bitch at the people who put up yet another 2 meter machine at 100ft, yet when someone actually does something different, you still bitch.
I'm not goan know th eguy who put a 900 machine 4 miles from my job, just have to see how to reprogram the work radios for it

Dude... You could donate the second one for the Southeast Hamsexy Infiltration Team. (We're the SHIT ya know!)
I've got a place for it at 250ft+ at the top of my office building. It should cover for all of us hamsexuals down in the upstate and since 3/4's of us are now P25 sexy, we need a P25 repeater!
