I heard from Gert PA3EYM and he mentions something very interesting to me.  Some of the numbers - for me - are difficult to send with a Russian Semi-automatic key with Cootie Dasher - Russian Cootie Bug or whatever you want to call it.

Gert comes up with an answer!

Hello David,

Pleasure to hear from you!
Thank you for mentioning my double lever bug key-in-the-making.

I still need to finish it, so it's good you mentioned it so I have it now on my to-do list now, hi.
In its unfinished state, I did give it a try as I really wanted to feel how it works.
I found that with numbers, you need to think a bit.
For example, for a 7 you need to start the dah's right.
And a with a 8 you need to start the dah's left.
And than again for the 9 you start the dah's right.
This to go to the dits in a natural left-right movement.
I hope this makes sense, hi.

The special Begali Intrepid sounds interesting.

I like your two youtube videos about "Merchant Marine Telegraph History by N1EA".
As a QRP I always dreamed of becoming a Radio Officer, but 'unfortunately' I was born too late, hi.
Those videos give a nice insight of a Radio Officer.
For me, ham radio is as close as I can get...

Kind regards, 73, Gert, PA3EYM
