Understand the sentiment, but more attenuation is operationally contra-indicated if the signals you're trying to work are weak due to temporary emergency antennas and QRP. Part of emergency preparedness is understanding various rigs non-prejudicially for their various strengths and weaknesses and choosing rigs for strengths and avoiding rigs for weakness as those apply to the specifics of an application. These days weak signals and close multiple transceivers call for the likes of K3's. At N4C field day we frequently had a CW station and SSB station on the same band with no interference, and actually without being aware of each other. No noise, no anything. I know what a K3's hardware AGC kick-in sounds like and that was also absent. This has been our experience for five or six field days now, and together with the small light size and portability, makes the K3 a top pick for FD. Not because of Koolaid, but because of proven suitability to the application. I'm waiting to hear about KX3's for FD, especially battery operation, long a specific niche for K2's. We did not have a K3S or K3 with KSYN3A for evaluation. We have a standing question of whether K3S/upgraded K3, with some horizontal separation, will be able to operate a few KHz away from each other on the same band/mode segment, e.g. the 40 CW station, and the GOTA station on 40 CW at the same time. Perhaps next year we will find out. N4C operated at the Grey Goose Farm near Creedmore, NC. The group was a large portion of the North Carolina East chapter of the Potomac Valley Radio Club. This group contains a significant supply of K3 owners, who regularly bring K3's to FD and multi-op contest events. For them portability and immunity to high RF environments are top-of-the-list reasons for purchasing K3's as opposed to other choices, easily serving FD style applications. At NY4A, also primarily manned by PVRC NC East members, going back pre-K3 the FT1000MP was the main rig, which had gradually replaced all the stalwart Japanese rigs of prior years. For some time the MP was the only rig seen there. When the K3's and other rigs with new generation RX came out, and the differences became known, The MP's were gradually replaced. A tally of the list of MP owning operators who had manned NY4A at some point indicated that 11 MP's had been replaced by 14 K3's and one Orion. Of that group, no one owns a Flex to this date. But neither would I consider any of them to be a "Flex-basher". I do know Flex owners, single home stations, who get outstanding performance away from high-RF multi-TX operations. Various problems with CW and spectral purity seem to be a continuing manufacturer's emphasis for solution. They're out there on a particular bleeding edge, with a particular emphasis, with its own set of problems. We'll just see what they do. Bashing not necessary. UPS currently has my 2015 K3 upgrade round: KXV3B, KSYN3A's, a second KBPF3 (A version) and finally a P3 and P3SVGA. I will get the new audio board when it's available.
