Yes, West Coast works.
' Will report back to group on final diagnosis and repair.

Does anyone have a recommendation for a service technician (stateside) to repair the 500M. I am pretty sure that the four Toshiba power transistors have gone to their reward, owing to the operator using the fault detection as an idiot proof device as opposed to a safeguard. The job would include checking the load fault circuitry.

Paula, 

 

Buddipole  make a   LI  battery pack and they have always  had great product.      4S4P A123 Battery Pack

 

HRO,   The candy store,  Carries the Bioenno Battery line.    It just depend on how much you want to spend, 

 

The newer battery Ion type are a lot less weight, run till they drop and cost a lot.   Gook  with whatever you come up with,

Paula,

This radio really wants to see 13.8V at all times.  I tried to run mine at 12V last field day and had the same problem you observe.  I haven't had time to experiment to see what the power vs voltage thresholds might be, but the safe bet is to just figure out how to get it the 13.8V.  An unfortunate limitation on an otherwise good radio.

Cheers,

Joe

Re: CAT settings help needed - Solved

 

When I operated my IC-7000 portable I used an auto/airplane converter for my laptop. The battery is OK, but I had this converter for long term operations.
As to the IC-7000 it is fairly sensitive to voltage for power. I don't know the voltage where it drops out and I have not had a problem with CAT in portable operations.
The best batteries to power the portable operations might well be LiFePO4 which has a higher voltage and maintains that voltage level longer and can be discharged to a lower level without damaging the cells like a lead acid battery.
For example a lead acid (both flooded cell and AGM) can be discharged to approximately 50% where the LiFePO4 can be discharged to 20%. While it is being discharged it will also maintain the voltage higher and have a lower internal resistance which would mean higher voltage under transmitting load.

After much experimentation and troubleshooting, it all boils down to low voltage. When I put the laptop on battery power the CAT control would not work, but it was OK when the laptop was on shore power. The solution that allows me to use battery power is a USB Y cable that will allow me to draw current from two USB ports to the USB/Serial adapter. That supplies enough voltage to function properly. 

I still need to identify an optimum 12v source of power for the radio. What type of batteries are best to power the rig for portable operation? I tried using  a Milwaukee inverter on an 18v battery and it was OK transmitting 10-20 watts, but anything higher and it would reboot the radio.

So it is the laptop itself that is the problem. Don’t know where to go from here . . .

Does the laptop have a VGA or any other connector with screws on it.
From there route a cable to the transceiver metal case,
thus connecting laptop ground with rig ground.

maybe that helps.

Since something is obviously different, I would check things like the voltage and for noise on the USB port.

Hi Paula,

 

Is it possible that RF is getting into the USB ports…. I have to use a fair amount of ferrite here in the shack (and I suspect that it may be as challenging while portable).

 

Used a kit from Palomar Engineers – every single piece in the kit was used!  FT-8 / timing on JTDX and WSJT-X were very susceptible to drop-outs from RF messing with the USB and Audio ports.

I use a Keyspan, and the current one is newer than I used before, but the same model.  I also updated to the latest Keyspan driver. And the laptop was upgraded to Windows 10. To troubleshoot, I tried all the different combinations of DTR, RTS, and different baud rates on both software and rig. Tried from WSJT-X and HRD without success. I did notice at one point while troubleshooting, that at 4800 BAUD I did get some small response from the radio, but no successful connection.

Any and all suggestions welcome. This one has me scratching my head, and it is probably just something dumb - but I’d love to figure it out today while I am still in camp.
Usually when testing a serial interface one connects pin 2 and 3
on the serial port. The data must come back as I type them.

Maybe it works with the 7000 connector also?

IC-28H and 37A

I've got a couple of those nearly indestructible ICOM IC-28H and 37A VHF transceivers (146 and 220 MHz, respectively) from the 1980s, and have not been able to find any online fan groups for them.  I'm hoping someone here might be able to point me in the right direction...
