Re: IC-7000 / Clipperton-L Linear
The IC-7000 has very small relays that do the switching and they are hard to change. I used the MFJ ARB 704 interface box with an Heathkit SB-200.

Re: Fixing the unrepairable IC7000
Hi,
When the two 12v tants are nearly all SC after 20 years, if one holds the power on button in for too long this takes the 4R7 resistor on the underside of the logic power supply board. The

Re: IC7000 no HF Transmit
I appreciate all the instructions and advice from Andrew, JD and James.
It has been a few days since I last did any testing. So far, I have found

Icom 7000 and 7300 as I have both work down to 12V reliably.
They get fussy at? around 11.8V.? ?That however is measured
at the rear panel connector.? Long wires and fuse issues even

Re: Hf tx
Hi Most Icom radios will not operate on low voltage, i.e. 12.5V lead acid, always feed with 13.8V min.
Yaesu and Elecraft will go down a bit.
