Few questions for making the icom marine antenna tuner to work with any universal HF radio systems, the antenna tuner systems include 3 variants, icom at-130 , icom AT-130E , icom AT-140.

I am trying to primarily make these tuners to work with 2 HF radio models,
1. Yaesu ft-450d
2. Home brew 3 band HF 40 watts transceiver

any ideas anyone??

Ham Radio - The CQ-Caller Interface.

This box provides older Ham Radios a voice memory keyer feature feature that is often found on modern high end rigs.
Voice memory keyers are often used in Ham Radio contesting environments , but can also be useful in general amateur radio use , for example when your trying to be noticed on a dead band , or if you are QRP.

Built on the same basic design as my Digi mode interface the CQ-Caller Interface has some things that my Digi mode interface doesn't.
Careful attention was payed to preventing ground loops and problems with RF interference.

Once connected to the audio mixer , simply play a pre-recorded CQ call mp3 file on the computer and it will key the radio and feed the audio to the radio.
