“Most portables have horrible sensitivity and even worse selectivity; it’s the latter that causes the worst problems,as strong signals in adjacent channels cut into yours and overpower it.”
Very good point. However if that were the case, then the effect would be in all directions from his TX point and not choose one area over another. Given the testing zone is within 1/4 mile, in all directions, and the result is a directional issue and not an overall range issue, I would say it isn’t the radio receiver being used that’s being selective and making the results run in circles….eh…pun or no pun…that’s the question. 😉
