Rigpix Database R L Drake Tr 3 Yes, it's high time that i worked on a drake rig on my channel. and i've got this lovely tr 3 to be the first.web sites referenced in this video: www . Drake had its act together from day one with well. engineered radios using quality parts. the tr 3 is certainly no exception with is crystal controlled first conversion oscillators and permeability tuned pto's. rock solid electrical and mechanical stability after a short warmup. the tr 3 was the only drake radio that used 12jb6 final tubes.
Drake Tr 3 Transceiver Tablelabel The repairs are well underway on my r. l. drake tr 3 transceiver. in fact, they are nearly complete. one big challenge remains though: the transmit receive. Mike wu2d made another very nice video about his drake tr 3 refurb. he cracked me up when he noticed that one of the calibration oscillators was 30 hz off. "let's pretend we care," said mike. indeed. but it was probably wise to tackle this problem, given how upset modern hams seem to get with 30 hz discrepancies. These are the major differences between the 1963 tr 3 and the 1978 tr 4cw rit: the tr 3 chassis is copper plated, while the tr 4cw rit chassis is not. i believe drake stopped copper plating chassis in the early 1970s, when the r 4c and t 4xc "c line" separates were introduced. Tr 3 repair notes. 15 9 99. all my radio repairs start with a careful cleaning. in case of drakes (4 line and similar cases, as the tr 3), i use to get both covers off, do a visual inspection for obvious troubles, as burnt resistors, charred wires, loose wires, cold solder joints and so on. check also special attention to the tubes; sometimes.

Here is a take back to the late 60s where i do a brief receive comparison between a 1960s drake tr 3 and current elecraft k3. Once finished, another round of voltage checking and smoke testing was undertaken to make sure that the drake tr 3 had every good chance of having proper operating voltages applied. . . . and here she is, the completed ac 3 in her new make over, dressed in wrinkle finish black, sporting new caps, new diodes, fuse and fuse holder, original bias.
