VXR7000 RX tuning / alignment.

[petnrdx]

Not familiar with these.
Service manual doesn't give much.
Have it apart, and I see there are not any physical tuning coils etc.
This one we have just programmed to the two meter band, and it's about -80 for 12 dB or so.
So pretty deaf. Was not that bad in the 147 part of the band, but we need it at 146.28 RX.
VCO voltage is .92
Is there alignment that can be done with the software or what?
Did some searching and didn't find much.
Anybody have and guidance?

Get Windows CE27 (it use to be free and IS online)
Change the target in the windows menu with the /d as such "C:\Vertex Standard\CE27 for Windows\CE27Win.exe" /m
Open CE27
PW: ansho-bango
Read the repeater,
S A V E what you read!
Check under under Common for Alignment, RX Adjustment, TX Adjustment, and TX Power. If it's going to be for HAM ONLY, try using 146MHz for your center freq. I'd step 3 or 4MHz away (maybe a little wider) for TX/RX Low/High and Lowest/Highest. Hopefully this works for you. Make sure to save/write down the original values in case it doesn't. 73s

Thanks, appreciate the info.
I have the software running on two laptops now.
Plan to read and save ONLY on one of them so I can't screw up and loose the original "file".
Have worked on hundreds of different kinds of radios over decades, but never any Yaseu\vertex\standard.
I see other people using them, so they must work.
Club here got one somewhere, so hopefully I can get it to work better.

A weird tuning procedure.
Not what I am used to with so many other radios.
But have it working pretty well now.
Only really odd thing I am trying to find now is that the PL deviation "wobbles" wider and narrower.
I have seen this before with other stuff where there is PL coming all the way thru from the subscriber and mixing with the generated PL slightly out of sync so they add then subtract.
Need to NOT be using disc audio.
I will find it.
Thanks again for your hints, saved me a lot of experimenting.

I have the same repeater. There was no tuning parameters for me to read from the radio. Would you provide the TX/RX and TX parameters that you ended up with please? I do not have all the equipment to do a proper alignment. If I can get a copy of your parameter settings, I will have a place to start.
thanks

If you follow the -m procedure this WILL be there. You do NOT want to try to just blast another radio's tuning info into a radio. You're more likely to screw it up worse than it starts as. Every radio parameters are all different! Even for reference...

The parameters was lost because the first time I tried to read it was with the wrong cable provided by the Antenna Farm. They had a Icom and Vertex part
numbers switched in there system. So now what is in there was the default numbers that came with the software program. CE27 for Windows. I called Motorola/Vertex support and they didnt want to help because I'm not affiliated with a company and this was going to be used as a Amateur Radio repeater. Do you align radios at home for a fee?

I don't have all the toys of a shop anymore and the shipping would be $$$. As it's going to be used for HAM, I would recommend trying to contact the tech group of a local club or another repeater owner. There's ALOT of people an Extra and GROL who have a whole setup at home and like being an Elmer for somebody who wants to learn. You could get by with signal generator and watt meter. Commercial shops are in it for the $ and now that Vertex is Motorola, they're a pain. If all else fails, you could try Yaesu and explain it's for HAM. It might or might not work, but the shipping would be to California.

I messed up. It sounds like /d or -d worked but you probably should do the /m or -m and use the same password. It gives total manufacturer access.
shortcut target "C:\Vertex Standard\CE27 for Windows\CE27Win.exe" -m
