Hi
I have a katsumi EK150 keyer and it lets me down when i need it the most, ie. in a contest ,rear dx station ect.
I have to clean the contacts to often and its always the dit side for some reason I'm going to fashion some silver contacts from an old coin before I throw it in the bin.
Does anyone have the same unit with the same problem?

That sums it up.
Not heavy enough for a doorstop in high winds.

However, a good paperweight!

Good keys and key paddles NEVER need to have contacts replaced. I've been using the same Bencher BY-1 paddles since 1978 (three of them, on three different rigs, all very frequently used) and I've never even had to "clean" the contacts.

Some designs require more TLC or
slight modifications for better field usage.

I am sure someone here will pay you shipping for it -- rather than the trash.
Marshall Emm may even be interested in it -- for his collection. One man's junk .. etc.

its been modified for 240 volts a transformer has been fitted to the top of it so its not much good for a collector.
