Anyone tried those relays?

I used the 12V version of GH-1 for a homebrew QSK box.
It works great. The whole box runs on +12V. There
is a capacitor boost that puts +24V on the coil for
a few milliseconds after PTT is asserted. The relay
settles within 5 milliseconds, limited by contact
bounce. IE, you cannot make it faster by applying
more than +24V.
The size is slightly different than the RJ-1 it replaced.
IIRC, the GH-1 is metric and the RJ-1 was imperial.
I mounted it in a rubber grommet so the metric threads
don't matter anyway.
