Dear Icom List Members, I have for sale an Icom FL-52A 500 Hz CW filter for the 455 kHz IF. I've tested it out and it worked well in my 751, 746 and R-75. Guaranteed in good working order. Looks are good too. $130 shipped to continental US. USPS money order only. Address is good in QRZ. Thanks, Roy AD6ZU
