The St. Louis Ham-Key that I used for the qso |

I worked 9 stations via FO-29 from my car with a mobile whip antenna for 144/430MHz!

Braving breezy, 16 degree Fahrenheit weather, I managed to erect a simple end-fed wire over the second story deck at my mother-in-law's Saint Louis home well after dark on New Year's Eve. I used the Icom 730 of my wife, KB0QJJ, her Lionel J-38 straight key, and an MFJ balanced-line tuner. Judging from the wicked RF burns I was getting, I seemed to be loading up my mother-in-law's house wiring against a ground plane formed by the antenna!
I had the good fortune to work Paul, K0JPL, in nearby Chesterfield, Missouri, on 80 m, having been attracted by his noteworthy callsign suffix that matches the abbreviation for the NASA facility at which I work. Now, whether the propagation between us was provided by skywave, NVIS, or the powerlines of AmerenUE will forever remain a mystery of SKN 2009.
Packed my Junkers key, FT817, and the HFp portable antenna and hiked up to the East Peak of Mt. Tam (a few miles north of the Golden Gate Bridge) for some portable QRP SKN operating fun. Had a great time! The bay area was socked in fog but at 2571 feet it was sunny and clear. As a bonus the noise level away from civilization was non-existent and all I could hear was CW signals. QRP (1.5 watts) was a bit challenging in the crowded bands so appreciate the efforts of those that made the QSOs happen at the other end. Thank you to AE6PX (0.5 Watts!), KF0QS, WC7S, and K9YKL.
Will do it again next year but bring a bigger battery and bump the power up to 5W!

Finally completed my homebrew station with a 40m five-integrated circuit receiver. I had started it last year, but didn't finish in time for SKN. Used the same two-tube transmitter from the last couple of years. I added a T/R relay so that it was easier to switch from transmit to receive -- and it also eliminated the risk of pumping RF into my K2/100.
Only had a limited time to operate on New Years Day. Made six contacts using five different crystal frequencies. It was fun pumping the old key and making contacts. Each QSO was unique and interesting.
The receiver added a lot to the experience. Had to make two mods to the receiver while operating. First, the BFO frequency was off, making the CW pitch too high. Second, the AGC time constant was far too long, making the recovery time after switching back to receive. 40m CW band sounded really alive during SKN.
I've put the details for my setup on my blog. Read about the receiver here: http://boringhamradiopart.blogspot.com/2009/01/little-receiver-that-could.html
And the transmitter here: http://boringhamradiopart.blogspot.com/2009/01/novice-40m-transmitter.html
Great fun! Can't wait to break out this pair again next year.

Homebrew 40m Receiver inspired from the NorCal Sierra. Dial tuned 150 kHz in four full turns of the knob. |
Peek at the insides of the receiver. Very simple layout with three-crystal ladder filter for good selectivity. |

Only time for one contact, and that was with K0SX. I always have good intentions of spending a lot of air time on SKN. but it doesn't work out. My aim is to have some vintage gear on the air in 2009, the station I had in 1959. My calendar is marked for SKN !
Many nice signal were heard back in North Dakota, and look for W0RTK on the bands this winter Oh yes, K0SX had a very good fist and a joy to copy!!!! Clarence

It was a good time listening to all the QSO's going on. I only made 1 contact, and realized how rusty I actually was! But I enjoy it and intend to get the straight key out more often. I use a Logikeyer CMOS III for CW contests. It was nice to use the straight key again and I'm definitely going to participate in next year's SKN.
A great time. I worked only five other hams during SKN, but they were quality QSOs. I used an old Kenwood TS-520 without a CW filter and a SpeedX hand key. I have been thinking about using a straight key more often during this year, but we will see. One gets addicted to the modern electronic keyers. 73, Dick
