T i m explained on 22/10/2018 :
I was and for quite a few years and it was both interesting and useful
(pre affordable Internet especially). I could get into GB7HSN
(Mottingham) on 2m pretty reliably (Pye Westminster + home made TNC)
and then later on 70cms on another ex PMR rig and a Kantronics KPC3
(was it)?

Yes KPC3, I still have one in the shack. I also had a high speed link,
the Yagi for which I took down a couple of years ago. I also tried to
generate interest in getting a 2.4Ghz system set up, using adapted
commercial equipment, I even carried out a few successful long distance
experiments with 2.4.. Idea was an emergency backbone, should the
Internet or telecoms fail.
