Icom IC-2100h Crackling Audio Repair

[@paulgrindley8192]

Thanks for this video. I picked up one of these IC-2100h radios used, in excellent condition for almost nothing. It started crackling really bad and I had a couple audio reports of noise and hum. Found your video and gave it a go. I used a UV light on the board and noticed that there was some sort of coating on the board and that much of it covered the copper rings as well. A little bit of DeoxIT D5 and a very light scraping of the copper rings and it cleaned up nicely. I picked up a bunch of #4 star washers and reinstalled the screws and it's working perfectly again. The UV light idea was a complete accident. I was trying to show my wife what I was trying to fix and it was the nearest flashlight laying around. Happy accident. Thanks again.

Interesting....thanks for the tip!

[@deanblake5072]

Works. Had two IC2100h radios ALL had crackling. This procedure worked well. Thanks

[@warplanner8852]

Good analysis and fix. The two additional screws probably cut down on the microphonics as well, These are rugged, well made radios. Not flashy but a giid bargain that will serve one well over many years. Additional recommendation is to throttle back the high power output with the interior pot to about 80-90 percent of the max and save the finals.

Thanks for watching and taking the time to comment. I agree - this is a good rugged radio. My only complaint is that it seems more susceptible to intermod than my other Kenwood and Yaesu 2m mobiles.

Thanks for the video. I'm about to buy a used 2100h from my local candy store and wanted to look on YT for any issues. Hope I don't have this one, but I'll know how to fix it. I sure appreciate you sharing wisdom-

[@RicardoBugiganga]

Thank you for sharing this ! God bless you 73's

[@76ersnet58]

I had the same crackling problem with mine but I added washers and it fixed the problem, thank you!!

[@RicardoBugiganga]

Thanks a lot for the help! In ten minutes I solved my transceiver problem.😀👍

[@hamidsk2573]

thanks for sharing this valuable experience, I was wonder if you have any video which explains component and subsystems of a typical VHF radio transmitter

[@dustoff499]

Awesome! I'll have to check and fix mine if needed - thanks. I do agree, it's great radio.

[@dustoff499]

Yep. Added no. 4 star washer and problem resolved.

[@George_S.G]

Another great video brother , thank you!!

[@scotreece5795]

I have a loose knobs volume and squelch. Do you know where I can send my radio to be repaired. IC 2100 IS my radio. TIA de KN4CBS

[@SevenFortyOne]

I don't know of anyone who repairs radios affordably. You can try icon direct but be prepared to pay more than the radio is worth

[@AsifAli-pq2eq]

friends i have icom 2100 its problem its sound not going far whats problem?

[@ryandys8217]

My 2200h has considerable less signal and recieve range than my kenwood 281 and yeasu ft2980. Have you noticed this too?

[@SevenFortyOne]

I never compared them. But...the icoms squelch also doubles ad an rf gain so the higher you set it the more the rf gain gets turned up. I really don't care for that feature

[@dikispwd4152]

Thank u OM...i will try soon. I have same problem with u

[@shaofuchang515]

Whats the impedance on the internal speaker? As well as the output rated for? I recently acquired a used Icom IC-2100H to which the original owner had discarded the user manual.

[@SevenFortyOne]

I'm not sure. But you may be able to get a manual from the icom website for this radio.

[@diwastandukar1196]

[@HertzTechnics73]

need help sir...my old icom ic 2100 no rx....please help me. thanks

[@tolakangin2042]

If icom 2100 no rx, what problem for this?

[@steveh130]

couldnt u have just roughed up the copper around the screw holes, and tinned them a bit to build them up?

[@SevenFortyOne]

Yeah - you probably could do that. Although, I wouldn't rough up the copper. I'd use a little no-clean flux just to get the solder to wet and then you'd have to make sure you got a good even flow to make sure the screw head makes contact at more than one point. Good idea!

[@steveh130]

a really small piece of scotch brite will brighten up the copper foil, but yea flux and enough heat will do the same. As u tighten up the screw, u squish the solder to a custom fit...and solder it really hard to oxidize, at least way harder than copper. Also thx for the 2100H bacic programming. I got a 2300H today and it helped alot. Im a brand new ham and just made my 1st contact 2nite. I held a novice class ticket back in 1985 but let it expire.
