I have a Drake TR-7 with the second version of the NB-7 noise blanker
(not the nb-7a). It is not very good at blanking out noise. The noise blanker on my Cobra 148 NW ST (cb radio) is far superior at blanking power line noise. Are their any known modifications for improving the Drake NB-7 noise blanker or any replacements for the NB-7 noise blanker? Michael Rawls |
