check with Bob W7AVK e-mail, you "fix" it -> rolfb <at> accima.com
As far as I know he has both the high and low powered diode and at a really good price. I got some from him recently. He also has (had) the TR7 service extender boards too. Both something you need to keep the TR7 going when they act up. I have no interest in Bob's work other than a satisfied customer of all the above mentioned pieces parts. 73, Ron WD8SBB --- On Tue, 11/22/11, [email protected] <[email protected]> wrote: From: [email protected] <[email protected]> Subject: [Drakelist] TR7 PIN diodes source To: [email protected] Date: Tuesday, November 22, 2011, 12:33 AM It's looking like I may have TR switch problems (diode has the same resistance either direction. This is the high power PIN diode in the TR switch. Does anyone know of a current source for the UM 9400 (or MA4P1200) PIN diodes in the TR Switch? Are there any substitutes for these diodes? Many years ago I got some from Down East Microwave but they don't show them anymore.
