Default VHF 'skipping record' sound

Anyone else experience this? VHF sticks on 16 and sounds like a vinyl record bumping on the lable. Not sure what is causing this . Coincides with another event that i'm trying to track down but would rather get unbiased responses before describing it...

I think I'd call the manufacturer's customer service & describe your problem.

Well, when did it start, how long has it been doing this and does it do this all the time? Does it do it everywhere or only in one location?

Is there another VHF radio on board that is turned on, tuned to that channel, and stuck on "transmit"?

You should probably tell us about the other "event" as they may well be related. Providing all the relevant information (and none of the irrelevant information) helps greatly in diagnosing the problem.

Ono other VHF on at the times this has happened.

HDS goes funky and loses bottom. Vertical lines etc etc.

Doesn't always happen when HDS dumps on me but HDS always dumps when VHF 'skips'.

To see if the HDS is the source of the interference you hear on your VHF Marine Band radio, the next time you hear the interference on the VHF Marine Band radio, shut off the HDS. If the interference on the VHF Marine Band radio stops, there is a very strong chance the source was the HDS.

Ditto, try turning off the sonar-F/F and see if it goes away

Did it sound like a 78 or a 33 record...?

Being older I used to play both.

Boy..that hurts..

I read a a story about a grandfather telling his young granddaughter that when he was a boy tv's did not have any color..just black and white.

His granddaughter thought about that for a moment and then asked.." Grandpa, when you we a boy..did Crayons have color?"

Sounds like interference from your ff.

Well I've tried turning VHF off but ff doesn't respond. Might not though without reset. Will try turning ff off and should see immediate VHF response. Thanks!

You cannot test the VHF Marine Radio to see if it is the source of interference to itself by turning off the VHF Marine Band Radio. It is quite likely that a VHF Marine Band radio will not interfere with itself when it is OFF, but this observation will not prove anything in your case.

I recommend you follow the test procedure I described for you in detail in my earlier posting.

Well, if that's not confusing, I guess nothing is.

If you turn the VHF off, you will hear no interference throough it. That will solve the immediate problem, but I suspect you would like to be able to leave the VHF on so you can hear important calls.

It comes naturally to some of us, but if you are getting electrical or RF interference on your boat, notice what is turned on when this happens and then turn things off one at a time untill the interference goes away.

Once you think you've found what is causing the interference, turn it back on and see if the interference comes back. Turn it off and confirm that the interference goes away.

Once you have identified the cause or source of the interference, post all the information here and several people will make suggestions on how to eliminate or minimize it.

I don't want to give my age, but here's my first cell phone:

I had an standard horizon with a click noise that cycled . called service and they advised several adjustments, of which turning off dual watch eliminated the annoying noise.

Interesting. My ICOM 422 has been doing the exact same thing on 16....only 16. I scan several channels when underway with 16 in watch and it would stick on 16 with that ticking sound. My assumption was that somebody else's radio was screwed up like constant keying on 16.

That can happen but not forever.

Turn things off, one at a time untill the ticking noise stops. Turn the last one back on and if the noise starts again, that is the source of the problem.

My plotters cause my VHF to stop on channel 68 and produce a "white noise" sound. I determined the cause a long time ago and I'm working on a solution (slowly). In the meantime, I leave channel 68 out of the scan sequence.

My new LED cabin lights cause the local public braudcasting channels on my TV to freeze (channel 7). I just turn them off when I'm watching channel 7. I'm working on a solution for that also.

I just found out my LED anchor light blocks the VHF weather channel 1. I have replaced the light (for other reasons) and I haven't checked to see if the new one does this or something else.

Trouble shooting (anything) is a thought process. Is there a problem? What is the problem? What could possibly cause the problem and why? Figure out a logical test proceedure and carry it out. Analyze the results.

.

what i meant by that was since my ff fritzes every time the vhf does the skipping thing I had hoped to clear up (and thus verify interference) the ff issue by shutting vhf off.

Ron is right on, again.

Trouble-shooting involves a mental flow-chart, to logically eliminate what is not relevant and what is relevant, generally by the process of elimination, or, sometimes only by substitution of components...the latter being a last-resort, and virtually an admission of diagnostic failure.

We have all seen abuses of "throwing new parts at it" syndrome. That approach gets expensive, fast...but, ironically, can actually be cheaper than visiting a dealer...sad to say.
