Kenwood NX-200 NX-300 Receive issue

[hfdrick5488]

Hello, I apologize if this question is somewhere else in a thread, but I couldn't find it. I am on a Fire Department and we have appox 35 portable NX series radio's. Of them we have had (2) so far that have developed receive issues out of nowhere.(They will not receive at all) I send it to our tech's and they send it out to kenwood on warranty repair work, however no one will tell me what is going on with the radio's. My question is if anybody knows what is happening to the radios and if there is a recall on them. I can kind of foresee all of our radios having the same issue at some point and I just want to head this one off before I have an entire department with a bunch of paper weights.
Oh and we are nearing our 1 year warranty.

Thanks for your help!

Rick

I haven't seen any service bulletins regarding them.

I've got about 300 of the NX-410's and out of those I had one bad display and that was it in 2 years (so far). Kenwood replaced it. Other than that, I did find 2 bad antennas, not sure if it was a manufacturing defect or from abuse.
Yes, the NX-410 is a different model, but if we are looking at an overall Kenwood issue, I haven't seen it.

In addition to the above, I've got about 50 of the NX-900 portables, no issues with any of those in 2 years.

I had one of our NX-300's start having issues on our trunked system, it would go "out of range" for no reason while in known good areas of coverage. We sent it in for repair, and it ended up being way off frequency. They re-tuned it, and the radio has worked flawlessly ever since (this has been about 3 months now). The radio in question was over 2 years old, and it had worked fine on the system up until this happened. I was concerned as to why this radio went off frequency and asked Kenwood if this is a known problem, of course they said no. So far I have not had any other off frequency radios so it might of just been a fluke. Our system runs on very narrow band (6.25 kHz) so the radios have to be tuned dead on to work good.

Ask them if your radios were just re-tuned because of being off frequency.

That is why all radios should be looked at by a properly trained and equipted radio tech/shop at least once a year.

Couple of years ago one of my personal NX-200s (brand new) went off freq and was flakey. Could not warp it back on and stay. Sent to Kenwood under warranty and they replaced the reference oscillator. Maybe a bad lot??? Anyway, works great now.
