I am selling a Drake SPR-4. It has extra crystals for 3.5-4.0, 14.0-14.5,
21.0-21.5 and 28.5-29.0. The front panel has some small marks and the top
cover also has some light marks.
It was recently aligned and works well.

I have also done the 10M conversion and Jim is absolutely correct about the

Hello Jeff & the group,
Probably the most versitile keyers ever made are the AEA Morsematic series.
They have both positive and negative keying output and will key the Drakes
without extra circuitry. If you like bugs, the automatic dash repeat can be

I need to replace the power switch on my L-7.
I have not pulled it off the shelf yet. It looks like I'll have to remove
