HT1250 Problem?

[N4KVE]

How well does the radio work on other freq's? Does it sound bad on every freq you listen to, or just this one?

Sounds like it either needs an alignment, or it could have a bad front end filter.

Either way, it needs to be put on the bench and checked out with proper test equipment.

The Cherokee VHF system is pretty robust and you should be getting stellar receive with a decent portable, unless you are deep inside someplace like the outlet mall or in the low spots around Waleska.

You know of any places around the area that would be able to test it?

If they aren't using companding then it should be off or it will not sound good... Have you looked at the RX audio settings? Is it Disabled, Compressed, Low-Level, etc?

It could be something like a bad speaker... do you have a RSM to plug in and try?

Haven't looked into the RX settings, I have 2 mics and it sounds the same way through both of them.

So after listening to what it is doing for awhile, I can now accurately describe what the audio sounds like. When I'm indoors, it's a muffled static..kinda sounds like a fan is running every time there is audio. When I am outside with it, it's better, but there is still that weird muffled static to a certain point.

Diversified Electronics in Marietta is who maintains the Cherokee, Cobb and Bartow systems. They have GREAT bench techs and are a full service MSS.

Any chance you could provide a audio sample? Out of curiosity, may not be the issue but do you notice or have a hum type issue when the radio is emitting audio during traffic? To point it sounds like buzzing or getting interference? Figured I'd ask you never know.

Please see this at batboards. It may help if your issue is similiar.

The HT1250 has a pretty stable receiver, have seen very few that needed an alignment over the years. How it transmits is not a concern and the wideband/narrowband mentioned will not give you distorted audio. Why dont you put in a local NOAA weather channel and/or another area frequency? Simple troubleshooting to figure out whats going on. If everything is distorted than its obvious you have a bad radio.

Static as in low signal strength? If so it could be:

- Radio has a RX issue as stated before, off frequency, wrong antenna on radio, etc.
- Are you in the coverage area when trying to listen to the FD?

You'd be surprised how many times I get an HT1250 radio in the shop with an HT1000 antenna on it. Two totally different antenna connectors. They're not interchangeable.

My big one is XPR7550s with XPR6550 antennas or vise-versa.

Thanks for the help everyone. I just picked up the unit from diversified electronics, and the radio was in need of alignment.

 

[FirstDue5]

The frequency was off by 30hz

 

[RFI-EMI-GUY]

Only 30 Hz? It will drift that much if you breathe near it. Your sure it wasn't 3 Khz?
