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.

More ham radio and short wave radio videos by gregW:-) OH2FFY at - 'HamAndShortwaveRadio'.
