I have checked out Lesters youtube channel and other radio shop channels. I feel for anyone that paid Lestercustom to "enhance" their radio. The guy replaces two capacitors and filter (reduce bleed over) on a Stryker 497, then claims his "tuning" gets solid 200 PEP Watts. D-rail $1000 modified Stryker 497 don't get near that.
When Lester turns RF power all the way up, the watt meter goes backwards when talking. He then turns RF power down half way and says "this is the sweet spot".
He won't reply to emails and has youtube comments disabled.
