Re: Good ICOM Tech for repair?

Steve W3AHL
 

I agree with Mark's reply that your radio turning off when you transmit is probably due to the poor quality fuse holders that Icom uses.  Pulling the fuse out and replacing it may cure the problem briefly, but the only good solution in my experience is to replace the fuse holders with good quality 30-amp automotive style with #10 AWG pigtails.  And throw away your current fuses and replace them also.  Or remove the fuse holders from the 7K's DC power cable and use a fused RigRunner if you need to power multiple devices with PowerPole connectors.

As far as increasing noise levels on HF, that varies a lot by band, regional/national weather conditions, antenna type, etc.  You appear to live in a pretty densely populated area, so there is a good chance that you have RFI from neighbors' appliances, lighting, power transmission line problems, etc.  Or your own house.  If the radio is noisy when connected to a dummy load, then it is a problem with the radio or the power. 

If fixing the fuse problem doesn't fix the RX noise, try eliminating your own house as the source first.  I suggest powering the radio off of a 12 VDC battery and turning off power to the entire house at the electrical panel.  If the noise goes away, flip one breaker on and listen for a while, then flip another one on.  Don't go too fast.  You may have to turn on lights, TV's, air conditiioners, etc. on each circuit to get the noise back.

If you are convinced the noise isn't coming from something powered by your house's electrical panel, then its time to drive around the neighborhood with your radio tuned to a problem band and see where the noise gets louder.  If you don't have a mobile HF antenna, you might enlist the help of local hams that have a mobile HF antenna.

I doubt that either problem you are reporting needs to go back to a service center for repair.  But solving the RX noise problem is often not easy.  When I moved to my current location 8 years ago in a fairly rural area, my RFI noise level on many bands was S8.  And most of it was from my new house.  It took me several months to get it down to less than S3 (not including atmospheric noise).  But it is possible as long as it is your house that is the problem.  Fixing neighborhood or utility line problems is a little more challenging....

J Tregre (AG7EG):
My IC-7000 smoked the UHF output finals a few years ago & I sent it to
for a quick repair. I have had Scott Malcolm repair several of my Icom radios
(I have never sent any of them directly to Icom) & his work has always been
excellent, quick, & inexpensive. He'll even do a bench check & provide you
a $$ estimate before the work begins if you'd like.

In the case of my IC-7000, he was able to repair the UHF failure & also found
the soldering in the VHF section to be questionable, so he cleaned that up as
well. He applied the new grounding springs & tested everything before sending
it back to me . . . it's been flawless ever since.

From my personal experience with several Icom radios sent to him for repair
(IC-706MKIIG, IC-7000, IC-756PRO, etc.) over the years with a variety of needs,
I would personally highly recommend Scott Malcolm to get your Icom radio
repaired.

Good luck !!

Do you have blade type fuses in the power lead? If so pull the out and plug them back in. See if that solves the problem.

In the real Icom OPC-1153 the twisted pairs are used correctly.  Mic audio and mic ground are on a twisted pair (pins 5&6).  8VDC and Ground are on a twisted pair(pins 1&8).  This reduces noise pick up on the mic audio and RFI in the cable from power current digital switching.

A standard CAT-5 cable does not pair these signals correctly.  You can cut off the connectors and rewire it however.  User quality connectors rated for stranded wire. 

The molded connectors on a factory made aptch cable are nice to have though, so unless a critical evaluation of your mic audio by a local station on multiple bands with a good set of headphones reveals an issue, you could probably get by with a standard CAT-5 cable.

Or rewire it correctly and use a flexible adhesive to strain relief the RJ45 connectors.

For longer cables in high RFI environments, use shielded CAT-5 (STP) with the drain wire connected to the radio chassis, assuming it has an RF ground connection (which of course it should have).  Shielded cables are a little stiffer.  Don't get the ones rated for exterior use, as their jackets are really stiff.

I am piping the screen to an in dash DVD player so that the screen is in my peripheral vision while driving (safety). That is a composite video connection. I am currently using a mono to RCA cable for that. It is short though at only 6'. I purpose to run a male mono to male mono into an RCA to mono adapter into the back of the player. For quality of the video.... would a stereo cable be better????? I am not sure if that would work or not.

I am just going after a very quality, clean, and professional install. I am taking my time with this and going to do it right the first time. :) I have the player already up and running and the rig works good with it.

Suggestions??????

I recently posted about mounting my 7000. Now I have a new question......

What are the best extension cables to get for my rig???? I looked through the messages, and could not really find the right info.

I am going to be using the ClearSpeech speaker. That comes with a stereo cable, but I will be getting a longer one. One that I am wondering about is the video cable. I am piping the screen to an in dash DVD player so that the screen is in my peripheral vision while driving (safety). That is a composite video connection. I am currently using a mono to RCA cable for that. It is short though at only 6'. I purpose to run a male mono to male mono into an RCA to mono adapter into the back of the player. For quality of the video.... would a stereo cable be better????? I am not sure if that would work or not.

I am just going after a very quality, clean, and professional install. I am taking my time with this and going to do it right the first time. :) I have the player already up and running and the rig works good with it.

Suggestions??????

thanks a bunch in advance :)

Re: [IC-7000] Re: Help Identify IC-7000 version by mainboard for MARS mod

Thank you so much!  I found a supplement that identified my main board.  Yes, 6249.  iTypo.  iApologize. 

The already missing diodes scared me, but I went ahead and remove the 3rd.  So far, I haven't destroyed anything.  

Thanks again!

I have service manuals for both Main board revisions (its 6249 not 5249 right?)  The board layouts are identical, but I can't be certain what the factory diode configurations were because of the 60M mod in 2012.


If you e-mail me details or a picture on how your board is different I should be able to answer your questions.

Hi, all.


I want to do the Extended Transmit Modification for MARS on my IC 7000.


I HAVE the service manual. BUT - It calls the main board B5249G (Golf).


MY main board is labeled B5249O (Oscar).


My diodes' layout don't look like anything in the available Mod
layouts. The current Modification guides I find all look like the
B5249G. Help!


I do not want to pull any diodes on the "assumption" that it would be
the right one because the others show the diode in that position.


Help?
