Re: Drake W4 wattmeter part three

Re: Drake W4 wattmeter part three

Re: Drake W4 wattmeter part three
*** I *loved* my TS-830S. Best radio I'd ever had. My only problem with it was the crappy circuit boards. They were not very tolerant of rework. - Jerry, KF6VB

Re: Drake W4 wattmeter part three
Yeah, we all have "those projects". I'm finally tearing into a TS-830S that I thought had RF switching issues. It turned out that the meter switch wasn't making contact. I took it apart and cleaned it

Yeah, there were some surplus Motorola repeater rack meters floating around eBay for a while that were almost the correct Jewell version but were more sensitive. I bought one, added an external shunt,
