Sorry, Denis, but do you mean a VOX, or something else?

Hi John

No, A voice keyer for contests etc. I use the VoiceKey Express software
but I have to highlight the programme to activate the keyer and then
activate the logging programme to log the station. If I had an external
keyer hooked up to the rig it would get over this problem

OK, I've been out of ham radio for a lot of years. What *IS* a voice keyer?

Is this a solid-state voice recorder/player, that lets you can certain
phrases the way a CW memory keyer lets you can CW fragments, to make it
easier to do contesting, or is there more to it?

Inquiring minds want to know...

Radio Shack used to sell a voice chip in a kit that let you record and play
back either 10-15 seconds of audio, or another one that I think could have 4
messages up to 5 seconds each. All you had to do was add a battery. Many
modified this into an
enclosure with relay for PTT for a one-button voice keyer. I think the chip
is still available, but not from Radio Shack.
Try some of the electronic supply houses.
You could probably easily then make the
interface from the pc to the voice kit.

Alternatively, there are a number of logging
programs that have the capability for voice
keyers right in the software. I think Logger
and N1MM are 2 of them, and N1MM is
free. N1MM is a contesting software being
developed by N1MM, but a also a group
effort. Keying is CW, voice, Data modes.

Good luck.

=====
That family of integrated circuits is made by Information Storage Devices
Inc (ISD) ,San Jose -California
The early types (1992) were ISD1012A , ISD1016A , ISD1020A with
Record/Playback duration of 12 , 16 and 20 seconds respectively . The
respective upper pass band limits are 4.5 , 3.4 and 2.7 kHz.
They have an onboard mic amplifier , automatic gain control ,antialiasing
and smoothing filters and a speaker amplifier.

A number of units can be cascaded to increase overall Record/Playback
duration.
