Everyone has given me more food for thought. When doing some googling I did
find some simple circuits for handling the high voltages so, that's always

You can try Nebraska Surplus: http://www.surplussales.com
There on the expensive side, but have a good stock of HV components.

Since I work on a lot of different rigs, I installed the Jackson Harbor Press
Key All kit in my keyer (http://www.mtechnologies.com/jhp/). This
inexpensive kit ($13) converts about any keyer circuit to handle up to 500 V
2.5 amp +

Gents,
I just caught the tail end of this discussion but if it's about keyers
Drakes, Jackson-Harbor has a keyer kit that includes a heavy duty relay for

The DX-20, like many of the small transmitters of its type, is cathode
keyed. What this means is that while the voltage across a key is

Thank you all for the suggestions. I'll admit that I was starting to fall

Good afternoon. I'm new to the list.
I've had a T4XB and an R4B sitting on my workshop shelf for way too long and
have decided to bring it back to life. Don't have a lot of experience with
Drake, but do have 40 plus years in the hobby and an electronics background,
though I haven't done a

Wanted a replacement Drake L7 C46-C47 PLATE LOAD variable two section capacitor
for a rebuilt project.

Also at the risk of blaspheme, I'm a big fan of the MFJ keyers. I've
been using one with a vibro iambic, into my C twins for years.
Better to spend

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
example is

Another option is to use a transmitting ceramic capacitor of the
doorknob variety. The smaller ones are typically rated at 5KV and

I don't have a CMOS-4 so I cannot comment. I have a Tick keyer that
just uses a single CMOS PIC controller and I find I can use it just

Hi Dennis,
What is that one additional component, and where does it go?

Hi Steve,
I dug out my schematic and it actually takes a few components. My
recollection was only of the inductor. Basically you place a series
