Again, why not use the 12VDC to run your radios.
Charge with solar and run on batteries.

I used a Predator generator from Harbor Freight.  It is the power inverter type, no hash.

Look for one with FCC 15 certification .

I also found some good info here ;

Hi Ron,

Had the same problem many years ago when I used to work M/P and used the inverter to power my laptop. 

In the end I went to a marine company and they brought out a pure sign wave unit and plugged it into my van. I tested all the band and they were completely clean.

So I would suggest looking into a pure sign wave inverter and still put ferrite rings on the cables.

Good luck

Hi Tim,

If you decide to go the shop route, may I humbly suggest Scott Malcolm of Malcolm Technical Services? The man is an icom repair expert, and has fixed three radios for me, one of which is a 7000. Reasonable turnaround times, fair prices:

Good luck!

The mask post was, I believe,  Spam.  Did not read any further than it took for me to hit delete.

I know may be you tried before but, dis you reset the IC7K?
Have you checked the cable? Using hyperterminal or similar. Tx and tx are shotcircuited and can be done. I did it years aho with my first ci-v for the ic731.

Just wondering if you have accidentally changed the default address  of 70H (in the menu) to something else?

Re: ALC Problem

 

The ALC controls the power and this voltage will change due to a number of reasons. 
The set power from the CPU, SWR, temperature, current etc.
Take a look at the ALC line voltage to see what this voltage is doing as the power changes in the time frame you are interested in.
You have POVC, FORL, AMS, ICH, ICL, IDS, RELF, EALC, UNUSB, and ALCL that all affect power by changing the ALC voltage.y
Investigating this area for a voltage that changes with the power output should aim you toward the problem area(s).
If the ALC voltage does not change with the power output then it is likely that the problem could be somewhere else, but I would first rule out this area as it has direct causation on the power output of the radio.

Dear Paul,
I also suspect RD70HHF1 ..possibly replace with another one and check with dummy load,

Re: ALC Problem

Pasquale S
 

Hi Paul, thanks for your answer

 

It’s no a problem related to temperature, RF power goes up slowly, very slowly about 5 seconds to arrive 100 watt !!! This is the first time, then it’s faster.

 

In VHF and UHF there is no problem, so I suppose there is no problem with pre-driver and driver, everything runs well.

 

IN HF/50 I changed RD70HHF1 because I had a fault before; in your opionion, can RD70HHF1 be the problem ???? Vth is about 2 volt, it seems too little value.

Hi Pasquale ,

In what time frame does it go up? , is it slowly or fast , could it be a temperature related thing as something needs to be warmed up .

I think you'd need a oscilloscope to investigate the drama to see where the slow increase is actually happening RF wise like at the pre-driver or driver or even before that as being new finals i doubt if the issue is from there .

Also i'd be checking around the power setting dc rail for any variations but the Cro would be far quicker (if you have one) , 73 Paul .

 


ALC Problem

Pasquale S
 

 

Hi guys

I’m repairing an IC-7000, I put 2 new finals RD70HHF1 and I set bias 100% (1 A for each final)

But I have a strange behaviour ; the power goes up slowly, for example if I set 100 watt , power is 20 watt then goes up until 100 watt; same thing if I set 50 or 70 watt for example.

I change the cable, I use now one without fuses. I have done adjustment 3 times, no effect.  In VHF / UHF my 7000 is perfect, no trouble.

 

Any ideas ?

 

Thanks in advance

Oggetto: Re: [ic7000] ALC and audio Tx problem

 

I had this problem with one of my IC-7000s. My symptoms were full ALC on SSB and 100% + output on all other modes.
Turning the power down has no effect.
The ALC circuit gets one input from the SSB logic on the UNSB line to the Q1606 FET that changes the ALC bias.
In my case the FET was bad it I recall correctly. What happened was the voltage on the line that gose to the op-amps was low (?). What happened was Q1606 shorted and the two 2.2 meg (series R1641 & 1636) were always pulled low and did not change when switched to SSB mode by that signal from the NUSB line. if I remember correctly it is high when not in USB. 
Your mileage may vary.
I have attached a copy of the schematic for this part of the circuit.
IC1601 are the op-amps that vary the ALC bias to control power and fold back due to SWR etc.
