The Potomac FIM utilized in this website promotion has been talked about for several years, but no mention has been made so far as I’ve seen of it being factory re-calibrated at any point along the way.
According to FCC Rules the licensed stations must have their FIM equipment re-calibrated every year-and-a-half, so I’ve been told by a station engineer.
Any results published are very suspect based on that websites continuing character attacks on at least one popular transmitter and its manufacturer.
And then there’s Rich Powers: “I know others have expressed that the SSTran 5000 can outperform even the Rangemaster providing a eleborate antenna system is engineered along with complicated (evidently) tuning proceedure requiring advance equipment and methods.”
That is a biased remark and completely contrived… not supported by facts.
