"Rocco Lardiere" <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- Gents:
I have been reading the glowing reports on the Drake blanker on the list. I have several in my Drakes, and they do work well. However, my advice to N7IOH was to try to find another solution (see below). I like to be able to fine tune the phasing and amplitude of the inverted "blanking" pulses, and I can do that with the JPS ANC-4. Most people who try one won't go back - they do NOT introduce cross-modulation on the bands if operated correctly (no more fuzziness). They are rated at 150 W PEP (watch out if you run more than that through them) and switch RX/TX automatically. For best results, you can locate a "noise sniffer" antenna externally. Oh - one more thing - you can run multiple Drake stations through one of these boxes. It's a cheap solution that really, really cuts down on those pesky local noise sources. At the moment, mine is knocking down an S9 buzz on 40 to S1. MFJ now sells a similar unit, the MFJ-1026. I have not tried one of these, but it appears to have the same manual phasing and gain controls as the JPS. Just my humble opinion. 73, Rocco N6KN ----- Original Message ----- From: "Rocco Lardiere" <[EMAIL PROTECTED]> To: "n7ioh" <[EMAIL PROTECTED]> Sent: Sunday, November 14, 2004 2:00 AM Subject: Re: [drakelist] 4-NB Noise Blanker > Al, > > You will get all kinds of responses to your question.
