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.

 

Regards

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

OK Guys, the new Bluetooth CT-17B-6BT is now available and so is the new CT-17B-6USB VERSION 2 with detachable USB cable for more information see WWW.VE2DX.COM.

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.

ALC and audio Tx problem

On Tx, ALC is full scale on all modes but no output on SSB. Transmits on CW and AM but still getting full scale ALC on meter. Any clues? Thanks Peter

Have you double checked your address and such?

Hello group,

I cannot control my 7000 via cat. It's been 10 years since i tried it since I had it mobile all the time. I have a rig blaster plug and play and that works on my 7610 and Yaesu FT817ND, but not my 7000.

I measure an open circuit between the cat connector (ring/shield) and rig ground. I read that it means I have a transistor or smt fuse problem.

I opened the top cover and immediately thought, oh crud, I don't want to have to remove ribbon cables!

Is it time for a shop to fix this? Any recommendations for a shop? I am bummed, was hoping to use it for FT8 this coming weekend. I think I'll just have to manually run split and find an open tx slice. I think that's all I need to do and then send it off when I return home.

Any suggestions are appreciated.

Thanks and 73,

Do a internet search for ICOM IC-7000 mods and you will find complete lists of acceptable mods and videos on how to properly set it up.

Re: CAT (Remote) port is dead

Al Browne
 

From Memory and it is a while back now. There is a transistor in the input line that is very susceptible to damage from something as simple as plugging in or unplugging the cable to the signal link etc. But you'll need to look it up. I found it when I was researching how to fix a fried pre-driver FET.
Sorry can't remember the details

I have one of those HDMI-based separation cable kits and it works very well.
I think I dealt directly (rather than ebay) it was a year or so ago but if you get stuck, I can probably dig out the details

Re: Does anyone know how to formulate the CAT commands

Mike Binder - NA6MB
 

Not an expert on ACL, but I don't see a native facility to send a user specified CI-V command.
I believe the commands you have successfully sent are are regular rig functions that are built into ACL.
I have sent DVK commands via N1MM to my IC-7000 and it worked fine.
ACL does have the ability to send WAV (sound/voice) files and CW strings, so you can do voice files and CW if you want.
If you really want to use your internal DVK in the radio, you'll probably need to write a program using the ACL API.

For N1MM I think I used these commands...
  • Voice Message1 = {CAT1Hex FE FE 94 E0 28 00 01 FD}
  • Voice Message2 = {CAT1Hex FE FE 94 E0 28 00 02 FD}
  • Voice Message3 = {CAT1Hex FE FE 94 E0 28 00 03 FD}
  • Voice Message4 = {CAT1Hex FE FE 94 E0 28 00 04 FD}

CAT1Hex is the N1MM command to send the following HEX data over CI-V.

So, you need to find a way to send "FE FE 94 E0 28 00 01 FD" to play memory 1.

Note this is HEX data, NOT ASCII data.

Good luck!

Re: Does anyone know how to formulate the CAT commands

The CI-V interface is used the share band data with the logger.
You need a COM port interface between USB and CW key jack.

I have this setup.  If you need more help I here.
