THE AIRWAVES CALENDAR
THIS IS YOUR LAST AIRWAVES UNLESS YOU
HAVE RENEWED YOUR SARC MEMBERSHIP
FROM THE PRESIDENT'S SHACK
I am sitting here in the shack writing another AIRWAVES editorial. I spent the better part of the day working on another piece of home-brew gear. I love home-brewing, I must, because I sure have a lot of half started and unfinished projects around. This latest was an interesting project. It is a regenerative receiver that was featured in QST last year. It is unique in that the regenerative part is at the IF and has a tunable converter front end. My main purpose for building the project was to have a nice receiver for a little SWLing (That is Short Wave Listening). The circuit called for using the converter chip as the VFO as well. Well, I did not like that, plus I would have to build a buffer to drive the display as well. Yes, I know, a digital display on a regenerative receiver, what will they think of next? So I dug out one of those partially completed home-brew projects, a direct conversion receiver using a VFO and passive mixer. I got to only the VFO and the mixer and never built the audio or input ends. I pulled off the mixer and proceeded to work up a three band VFO. The thing really works and is now in a nice box along with the regenerative receiver.
The point of the story is to encourage all of you to try building electronic gear. Try a kit, or something small. Try that interesting project you saw in QST, 73 or CQ magazine. Do not worry if it does not look pretty, most of my stuff looks down right coyote ugly. Do not worry if you do not use the project afterwards or even if you do not finish it. Do not throw it away. Start a project drawer and slip it in there. Someday it will come in handy, or a part of it will. The great thing about amateur radio is that we are amateurs. We can experiment. We can try something new or something old. Some of the projects will succeed. Others fail. But, we will always learn from it. Give it a shot and bring it in to the April meeting and brag about it.

RENEW SARC MEMBERSHIP NOW
Yup. It is time to renew your SARC membership for 2001. Inflation has finally forced SARC to raise dues for only the second time since organizing in the mid-seventies. Memberships are now $20.00 individual, $30.00 family and $10.00 student/military. A three month grace period is given in which non-renewed members receive the AIRWAVES and the enclosed membership applications. After 31 March, non-renewed memberships are dropped from the mailing list. Support your friendly, local Amateur Radio club. Renew your membership at a meeting or by mail. The mailing address for SARC is on the enclosed application.
RAFFLE FOR N-I-C-E STRAIGHT KEY
Phelps TerHeun KF6ZVD, our 2nd VP, has organized a raffle for a small, very attractive, gold plated straight key to raise money for SARC treasury. This key is in the $100 price range and would look really good at any Ham shack's operating position. It is the Millennium Key, #81 of 100, by Llaves Telegraficas Artesanas. Tickets are $5.00 each or three for $10.00. Get your tickets from Phelps. The key will be on display at meetings and the drawing will be at the June meeting.

RECENT SARC ACTIVITIES
I am sure almost every Ham has heard about PSK31, it's many different flavors and how this mode excels in its ability to continue a QSO under very poor conditions. You can build your own interface with parts obtained from Radio Shack or you can purchase a complete unit from several providers. The purpose of this article is not to tell you how easy it is to become PSK31 active, there are already many articles covering that. I am going to tell you about some of the amazing QSOs Jerry Brooks KK6PA and I were able to complete using two meter FM.
Jerry got me started on HF PSK31 about a year ago. After working out the bugs in both of our interfaces, Jerry and I went on to make quite a few HF PSK31 QSOs. Many of these QSOs were conducted when the received signal could barely be heard, yet the PSK31 software and computer sound board were able to detect and decode the incoming signal.
After reading an article regarding PSK31 on FM in the October 2000 issue of QST, page 81, about how a two Hams in Hawaii were able to complete a PSK31 QSO using two meter FM, I thought this might be a useful mode for Kern County RACES. As most of you are probably aware, we no longer have a twenty-four hour a day connection via amateur radio into Bakersfield. In the event of a RACES call out, Eastern Kern County will most likely need to send messages to the Kern County Emergency Operations Center. Based on the success of the Hawaii Hams, PSK31 sounded like it might provide a more reliable path using modest station equipment, something that most Hams have.
Our initial road test antennas consisted of Jerry's base station of a 5/8 wave mobile antenna up about eight feet and a five element Yagi at fifty-five feet. The mobile setup was just a 5/8 wave mobile antenna. Both transceivers were capable of five and fifty watts output. After a minor equipment problem while heading towards Trona was fixed (speaker cable plug came out of interface box), our first QSO was held from Jerry's house to the rest stop just north of the railroad crossing in Trona. That QSO was completed using 5/8 wave antennas and five watts both ways. Jerry and I were both shocked that we could conduct a keyboard to keyboard QSO with 100% copy, no hits, with such minimal equipment. Trying FM voice from the same location was totally unsuccessful.
Next along the road was the pass at Slate Range. That QSO was a repeat of the Trona QSO: 5/8 wave antennas with five watts output power. This was starting to look good. Jerry wanted me to check out Ballarat so I continued north on the Trona-Wildrose road. I pulled over at the turnoff to Ballarat and I was thinking to myself that this is just not going to work. After dropping from 2900 feet elevation at the pass to around 1250 elevation at the turnoff, I thought there was way too much dirt and rock between us. Regardless, I switched to high power and gave Jerry a call. What a shock when he came back to me with 95 to 100 % copy. Wow! The only difference was that Jerry was now using his Yagi but still at low power. With this type of good luck, what else could I do but head north to Panamint Springs.
Well, it had to happen. I pulled over at the junction of Trona-Wildrose Road and hwy 190 and sent Jerry a call. Nothing. Okay, try again with a longer call. "KK6PA KK6PA KK6PA DE KM6JM KM6JM KM6JMI'm at Panamint Springs junctionat Panamint Springs junctionhow copyhow copyDE KM6JM." Jerry got me this time but only because he knew where I was and what to be looking for. Several BTU's (back to you) later, Jerry confirmed I was at the highway junction and not at the Panamint Springs resort itself. Well, at least we would be able to use this mode and equipment in a real emergency if nothing else was available. A beam or high gain omni antenna at the junction would definitely provide better communications. A high gain omni antenna would probably have been best since our signals were surely bouncing off the various mountains between us.
Completing the loop, I continued up to Crowley Point, past Darwin and on to Olancha. Jerry and I tried our last QSO at the junction of highways 190 and 395. That QSO was about the same as the Panamint Springs QSO. Definitely possible by using high gain antennas both ways. Next month, our PSK31 two meter FM road test to California City, Tehachapi and Bakersfield.
Twenty Mule Team Horse Ride
This year's Twenty Mule Team horse endurance ride went smoothly with no real laggards holding up the closing process. The drag riders came through about 0230 at the trestle leaving only the vet check five to close a half hour later and base camp to close in another two hours. One hundred and thirty-five horses participated with one rider each. The young lady who was the first of the hundred milers was in before dark. The weather was cold, but not too uncomfortable, and the wind was mild when there was any. It stayed dry. Jacky's map was upside down as usual and had to be interpreted for two new Ham radio operators. Dave KC6CEX promised to make us a more useful one if we would get the GPS data to him. We are in the process now. Thanks to the following Hams for making this all so easy. Dave Hunter KC7CEX, Mike Pope KB6NIZ (welcome back), Dave Stone KC6UUR, Dennis Farrell W6DWF, Phelps TerHeun KF6ZVD, Paula Gibeault N6OQQ, Greg Roush WA7IRW and Lloyd Brubaker WA6KZV.
Thanks to Greg who put up the portable repeater, and took it down again when it was no longer needed. All of the riders expressed their appreciation for our being there keeping an eye on things.
Volunteer Examination Session
The results of the 10 February Volunteer Exam Session are; Johan Beyers N6PBT upgraded from Technician Plus to General. Gloria Frasier (KQ6UU harmonic) passed the Technician and is now KG6FDV. Monty Schinn W6PFR, Jerry Brooks KK6PA and Bill Maraffio N6PR were the examiners.
Monthly Fox Hunt by Mike Herr WA6ARA
Yes, there was a fox hunt planned for February but yours truly blew it. I had plans to pass it off to another hunter to be the fox, but I came home from travel and left the next day to go out of town on a personal matter. It dawned on me about 7:30 pm on Saturday night that the fox hunt was suppose to have happened that morning. A thousand apologies. There will be a hunt on the 17th of March. I will make sure to get the transmitter to the fox early (fingers crossed).
Fox hunting can be done with a limited amount of equipment, as simple as just a hand held radio and your body. Come out on the Saturday following the SARC meeting, 17 March, at 0900 at the Heritage Inn parking lot. The frequency is 146.565 MHz.
