Patiently call 760-597-1500, ask for sales. Make sure you strap yourself in the chair before calling so that you don't hurt yourself by falling out. Have someone nearby with an AED, just in case. :-)
Thanks, but no thanks. I know what a new 141B card costs. I prefer to find a fellow ham or MARS member who has one for a reasonable price. I thought I had one located with an Episcopal priest ham, but he never got back to me. Second hand Datron gear in excellent condition can be found for 10% to 20% of the current GSA price.
Still waiting patiently . . .
