New Universal Keyer Module Only Kit

Build Instructions here

New Mk2 Version, now uses a MOSFET solid state high voltage relay rather than a mechenical relay, no jumpers to set and very easy to build, suitable for all rigs. This module now replaces the standard OSK keyer module we offered for the last few years

We have offered a very flexable 4 channel memory keyer for a couple of years but have had to disapoint customer with older Valve rigs that have a high negative voltage on the keying lines (like the TS830). Well now we are glad to be able to offer this new module that will work with both the most modern rigs or the older valve type rigs, our Unversal Keyer module.
This offers the same specifcation of features as our Universal desktop keyer but with out the jack sockets, mode button and case etc, ideal if you want to build it into your excisting radio or your own case.
