Richard Amirault, N1JDU writes on wara64 list:
“As a result of the work party a week ago, the “crunchies” that have been so much a pain lately are now gone on the [Waltham 146.04/146.64] machine.
“The work party installed a coax run for the previously installed secondary antenna. However, there was a problem with the coax and the single antenna system was hooked up again. Andy [WA1GEP], however, removed the notch filter for the intermod problem … since it was not helping anyway … and now the crunchies are gone.”
