We use a dozen K3 transceivers at W3AO, we've never had a K3 failure despite running as many as four K3s on the same band (CW SSB Digital and GOTA). The four K3s on each band do not interfere with each other either.
Our secrets to success: - same band antennas are horizontally polarized and oriented exactly end-to-end. Inverted V dipole and verticals are allowed. 100 feet of tip-to-tip spacing appears to be adequate, although we use much more. - We install W3NQN bandpass filters on every K3 to avoid overload from signals from nearby antennas for other bands. Its not widely known that K3 transceivers have built in bandpass filters. As far as I'm aware their performance characteristics have never been published, hence our preference to also also use external bandpass filters. 73 Frank W3LPL ----- Original Message ----- From: "Bob McGraw K4TAX" <rmcg...@blomand.net> To: elecraft@mailman.qth.net Sent: Friday, June 14, 2019 3:24:01 PM Subject: Re: [Elecraft] FIELD DAY PREP With stations running 100 watts or less and reasonable antenna separation, I've found no reason for a Receiver Input Protector. Although, it might be a good idea to circumvent a "screw up" by an operator. I've seen some mighty strange things done by knowledgeable hams at Field Day. 73 Bob, K4TAX On 6/14/2019 10:07 AM, KENT TRIMBLE wrote: > Have any of you used Ameritron's "Receiver Input Protector" model > TRP-150?
