In the winter of 2002/03 we decided to replace our aging Icom SSB with a new Icom. You would think that installation on a metal boat would be easy. Not so.
We had many problems with stray RF resulting in low output power and poor tuning. We were working with Eric Steinberg of Farallon Electronics and even he was stumped.
Finally Eric put us in touch with Jim Corenman, the author of the AirMail program that serves as the e-mail client running on PCs aboard member vessels of SailMail‘s e-mail-over-HF-radio service. Even though we don’t use SailMail, Jim got involved and solved our problem. Based on Jim’s recommendations we installed line isolators and our radio has never worked so well.
