But what amazes me is the number of amateur amps (both HB and commercial) that don't even *have* an RF-tight output compartment! The power supply, control wiring, mains wiring and even the RF input c

My HF station consists of an FT-1000D and Alpha 87A. Having recently replaced an 80/40 trap dipole which blew down a few gales ago, I noticed that even on the dipole's frequency of lowest VSWR and wi

Many thanks to those who responded on- and off-list to my query about anomalous VSWR indications when using an FT-1KD into an Alpha 87A. The consensus is that the 87A may have a minor problem with it
