Why not use a 2N3439 NPN rated at 450V or 2n5415 PNP rated at 200V and have
the safety margin?

I'm guessing that Dale's kit is using the 2N7000 as the output device.
They are rated at 70 V Drain-Source, Minimum 60 VDC. Most Drake

That's another keyer to look for.
I'm hoping to find something at the local hamfest this weekend here on Long

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
turned off. The keyers come up on upay

Also at the risk of blaspheme, I'm a big fan of the MFJ keyers. I've

Frankly, for some things, like calling CQ if you don't do it with an
programmed keyer, iambic is much more efficient. Squeezing off an A for
