ICOM IC-9100 Low Power Output Problems. Over the past couple of months, I had noticed some strange power output issues with my IC9100. I don’t use the radio a great deal, but at times, i would see the output power indicator drop over time, or fail to reach peak power, most noticeable on 70 cm FM, but also on HF.Seller: frr24 (1,697) 99.7, Location: Caledonia, Ohio, Ships to: Worldwide, Item: 265005350996 ICOM IC-7800 HF/50MHz TRANSCEIVER BROCHURE.
This radio’s receiver is surpurb with a ton of different settings and functions found on higher end radios and not to forget, ITS SDR!Yes you heard it, SDR, Software Defined Radio at it’s finest and I consider it miles ahead of other comparable SDR radios.I primary use my new base station as a CW, digital only station and hardly ever venture on side band any more. This past October, a dream became reality.When I first got my new radio, I could not believe the look, functionality – per – dollar and it’s overall high performance ICOM offers in a mid level radio. Ever since I first saw this radio, I knew it was my dream radio. My recent search into a base radio has favored my way to an IC-7610. Says it all.-Earlier 5-star review posted by G7EMK on Having owned and worked the iCOM ic 7800 since early 2005 I feel well placed to comment on this outstanding transceiver. The radio has provided flawless communicational enjoyment for 11 years.I bought one of my equipment in the U.K.
After testing my meter with my ic7610, I was still seeing low power out on SSB peaks and not anywhere near what I was expecting. I then visited Mike KD2DYY my Ham Neighbor and we evaluated my cross meter to ensure it was working as expected and tweaked it slightly. I removed and tested my meter separately, using my TenTec Omni-D and my Daiwa meter displayed the power I would expect, that is about 85w PEP. I made sure I was on High Power (90%), and I sure was.From that point forward, I started to rule out appliance failures.
I will spare you all of those details)I finally came to my senses and determined my new radio was at fault. Still low power output on SSB!(Cursing storm ensues…. No issues with any cables.Afterwards, I then disconnected my LDG AT-600Pro2 from the wire rats nest and just tested my radio and meter into a dummy load Cantenna. My non peak Bird Watt meter was not a good test but shows fluctuations in 15/30 watt range.From there it was total disassembly of my station and testing all of my cables.
Hardware Failure?!I could not believe it, 100% (Icom now works in percentage increments of relative power out instead of watts now… go figure) relative power output and I’m only getting 15-35 watts out.So I called ICOM over a course of 3 days and two of those days, all service technicians were saying “Nope, that is the way it works,” “Your all good, no issues.”I was not very pleased to say the very least.Finally A very knowledgeable person at Icom answered my phone call on this third attempt and he could see frustration and concern in my voice. I knew then it was not my settings.I also tested mic gain, drive level settings etc. Then Restored my settings and tested again. Guess what… I had that same issue (did not reload any settings).
Icom Ic-7800 Power Problems Manuals And Came
No answer and a brief pause, but He came back and said that several hams complained about distortion at high voice peaks and Icom wanted to remedy that with a much more aggressive ALC.Still taken back by this finding, I quickly came to my own conclusion, and it came down to quality. He could only speculate so I asked if this is that very case, why doesn’t Icom published this about SSB on their mid range radios. He even tried a IC-7300 and an IC-7100.Quite astonished, He looked around at some manuals and came to a suggested conclusion (not a confirmed one since none existed), that Icom 7000 series radios now have a very aggressive ALC limiting, especially in our 7610’s.Quite surprised, I begun to question validity of such words. Between all of his hollering, yelling and whistling into his test bench IC-7610 and me on my phone, he was able to replicate it my issues quite easily. He attempted to recreate my issues.
Also called ICOM Tech support again to have the rep confirm their suspicions of aggressive ALC is true. And the specs/advertising mention SSB power close to 100 watts in SSB, when the radio does not give you much more than the third of this power… “What do you think about this? Email me! UPDATES (See bold text for most recent update):12/2018: will be doing a video with several other meters showing this issue to rule out a faulty meter. While solving some audio problems with an overaggressive ALC, this radio is no longer suitable in SSB for the casual DX’er, the casual contester, as well as contesters, DXpeditions, and not rag-chewers. It simply does not perform at that level expected of a mid tier $3k SSB radio.“This is a poor SSB radio. CW, RTTY, PSK, DATA all work well!So here are my thoughts: If you want a rag chewing radio, this is NOT that radio you should be looking at, at least until this becomes an issue and hams complain to Icom to have this fixed. DXer’s dreams will also be shattered should this radio be used. Again, there are no issues with any other modes.
He also has communicated this issue to engineering and I asked him to escalate it. I also got in touch with Bob Heil to ensure my audio settings were correct to his microphones and adapters for my IC7610.On 20th of December, I discussed at length with another Icom Tech who had also seen this issue himself. Awaiting reply communication.
