I can only shake my head in awe of Howie's 8-transmitter FD, as well as other double-digit multi-transmitter operations . My hat's off to that kind of effort, believe me.

We used to do that, too.

But several years ago the Mid-MO Amateur Radio Club (NØSS) of Jefferson City, Missouri, decided on wire-only Field Days. We did so for several reasons . . . (1) those doing the work are aging; (2) those doing the work have no business being in the sun very long; (3) those doing the work are usually those doing the operating; (4) Missouri weather always throws 90-degrees and 100% humidity at us; and (5) none of us enjoy the labor of putting metal things together only to take them apart again.

Aside from Qs and scores, the goal for me (at 71) is getting the darn things up as fast as possible on Friday evening, seeing them stay up for the duration, and getting the heck out of there when it's over. To that end, erection of three OCF dipoles on 30-foot masts aligned end-to-end with 50-feet of separation took 45 minutes. Tear-down and site clean-up took exactly 33-minutes.

/THOSE/ are the reasons our 25-man crew happily stays at 2A!

Equipment-wise, we use nothing but K3s (one each for CW, SSB, GOTA, VHF). The CW and SSB rigs were often on the same bands at the same time with no interference, no phase noise, and no activation of carrier-operated relays. Both HF stations stayed busy all weekend.

Again, my salute to the big clubs, the big antenna farms, and the big scores.

But I suspect our level of fun was the same, with a whale of a lot /less/ effort.

This Field Day I operated once again with W4EZ the Orange County Radio Amateurs in Hillsborough, NC in an 8A effort. It was a lot of work setting up 6 towers and many wire antennas in mid-90° heat and high humidity but the end result was a lot of fun and Qs.

Despite our best efforts at eliminating cross-interference between stations beforehand by antenna placement, we suffered quite a bit of in-band phase noise interference. All three CW stations and one SSB station were using K3s, and no K3 station ever interfered with anyone else or with each other. Much credit is due to Elecraft for the transmit purity and receive performance of this superb rig. However, we experienced some pretty severe in-band phase noise interference ranging from S3-4 on 40 and 20M from various YaeComWood rigs, to an ear-shattering received S8-9 from a TS-570 running SSB on 15M when the noise floor was S0. Granted, with relatively close antenna spacing Field Day is a torture test for transmit purity, but sometimes it was difficult to tolerate...or operate.

Many of us now agree we would optimally be an all K3 Field Day next year but that is most likely out of the question. I am a big fan of the KX3, although for Field Day purposes it would be great if its phase noise was 10-20 dB less; more in line with that of the K3. That being said, a KX3 running digi caused less interference than just about all the non-Elecraft rigs.

One problem solving this scenario is the political issue of trying to tell someone they cannot bring their rig to the party. We did discuss holding a testing session next year to evaluate phase noise beforehand and accept or deny use of the rig based on performance, and maybe this will be viewed as being more impartial. After witnessing the problem first-hand, at least one op said he was intending to get an Elecraft rig. Elecraft owners are in the minority overall, so instead of Field Day being an inclusive club event, telling people it will be K3 only would achieve the opposite.

Other than the phase noise issue, FD was once again a lot of fun and camaraderie!

Cheers & 73,
