It's funny you mentioned the Yupiteru MVT7100. I bought an MVT9000M in 1998 and within a year and a half the squelch on it went haywire. I called the company in The Netherlands explaining my issue and they were not of any help and all they could tell me is I needed to send it to them and they had no idea what it would cost me to get it fixed. They did say it probably wouldn't be cheap. No estimate, nothingother than it probably wouldn't be cheap. They did say it had a digital squelch, something I'm still not sure about, and that they might not even be able to fix it but I'd still be responsible for costs to have them look at it.
What happened on my MVT9000M I still don't understand and I still have the radio. It would not stop on any signals no matter how strong. If I turn the squelch to just a extremely tiny bump from being opened up, it would not work or stop on any traffic. But if I was parked on something like the NOAA weather radio broadcast and I opened up the squelch all the way I could hear traffic. Of course this won't work having to do this on a scanner.
I had gone to Shreveport for a funeral and had programmed in Barksdale AFB and this is when the problem started while on that trip. Through the years I have repeatedly put some batteries in it and tried again but the same issue still exists. I wish I could get it fixed because it became a $800 or $900 paper weight just barely after the warranty ran out.
I know a lot of people did like the MVT7100 but with the policies and lack of any USA support for the radio, I'd be very careful using a company like that. Of course both models are no longer made and you cannot do any kind of PC programming or control of the radios either. It takes a long time to program frequencies and alpha tags by hand if you have a lot to program.
Since the topic of this thread has to do with possible squelch issues, I couldn't resist telling my Yupiteru story.
To this day I'm looking for any ideas or knowledge on if anyone knows of a fix for why the, what the company calls, digital squelch doesn't work. Oh yeah, and the audio on the MVT9000M was very poor and not loud. I don't know about the MVT7100 when it comes to audio but if it was supposed to be an upgrade to that radio with my MVT9000 (or maybe the model was MVT9100M?), I would wonder about the previous 7100 model. After they got their money from me, they didn't want to do anything to help it seemed like. And I know I paid close to $1,000 for the scanner back in 1998. I wish I had never bought it.
