Have finally gotten down to working on the two BC-654 transmitter – Receivers that are in the shop. Going to go thru and replace all the capacitors and also modify the range with the excellent K4CHE web page as a guide. Couple questions have come up.

First,

It appears to me that you have to unsolder the dial light stuff and do a lot of work to remove the receiver chaise in order to have access to the guts? Am I missing something here? Is there an easy method to get to the underside of the receiver?

Second,

Assuming that I will be operating the receiver for a while outside the enclosure, without the transmitter attached. The manual shows some four wafer switch thing along with seeing the board that Mr. Smith built up for doing this but I looked at the stuff that’s out there on line, lot of what I am seeing was not to intuitive, so I drew up this design for a box that will allow you to run the receiver outside of the frame. Please study the attached drawing and feel free to comment.

The plan is to start building this box maybe as soon as this weekend if I can get this access to the underside thing worked out first.
