Obviously, though, it's not possible to know if the winding has been scratching in making the bend around inside. So, my question is, to quote Shakespear, is my concern much ado about nothing?

Wayne, N6KR and Eric, WA6HHQ are our featured guest speakers this year. The title of their segment will be, Ultra-Portable HFpacking with the KX1. Following their talk, local HFpackers will be conducting our first KX1 Pow-Wow,which features live in the room QSO's with Pedestrian mobile KX1's. We will be using amplified speakers and extra wireless PA mics so everyone can hear the CW. Also, an Open discussion forum combined with a Powerpoint presentation of HFpackers using their KX1's wraps up the Pow-Wow. Real users will discuss the following topics: 1) Is building the KX1 easy? How long does it take? 2) How does one pack the KX1 when portable or Pedestrian Mobile? For the in the room live QSO's, we are designing a broadband wire loop for 20M coupled with a ferrite transformer to a BNC male connector. This loop was recently tested at a NorCal Meeting with good results. The compact loop should be efficient enough to work throughout the Marriott hotel, and is easy for the internal antenna tuner to match. Our goal is to use the KX1's like handheld HT's during the convention for fun. KX1 owners, and newbies should attend our forum to see Wayne and Eric speak, and to participate in the discussion. Bring your KX1's and toss a wire into the trees during our HFpack Zombie Walk in the Marriott Parking lot. We operate Pedestrian Mobile HF around 10PM on Saturday,and had worked many stations on 40M running only 5 watts. Last year we worked stations 900 miles away. Some HFpackers may be using their KX1's Pedestrian mobile with backpack mounted antennas. At the end of the entire forum, we will be conducting a Door Prize Raffle with donations from Elecraft, LDG, SuperAntennas, Buddipole Antennas, HFprojects kits, Doug Hendrick's kits, and Norcal. All we ask is that you must be PRESENT to WIN during the raffle. So if you are interested in buying an Elecraft KX1, or wish to see what others are doing when portable, or Pedestrian Mobile, the HFpack Technology Forum is not to be missed. 73, Ken WB6MLC HFpack Events Coordinator PS..

Re: [Elecraft] DMM Recommendation
Raj Good point on the refresh time. I never liked tuning for a peak or dip using a digital meter. Guess my analog brain doesn't like living in a digital world. I've picked up old analog VTVMs for a buck or two at hamfests and converted them to FET op amps in place of the tubes. Zero drift/warm up and all the advantages of an analog meter that runs on a 9v battery. If there is any interest I will write it up after I retire at the end of this year. Looking forward to more time for what I WANT to do. 73 John WA8KNE Rajiv Dewan, N2RD wrote: One of the characteristics I look for is response time / refresh time / time to read. It is much easier to make adjustments that depend on measured voltage or resistance if the meter quicks refreshes the readings. Some multimeters, especially some of the Flukes, are excellent in this regard. For example Fluke 170 series will detect open and short conditions as short as 250 micro seconds. It also has a loud beeper and I find it to be a great continuity checker.

Re: [Elecraft] Thanks ref - Antenna wire question for long spans
John others I am going to go in another direction on wire size for long spans. I have been using the silky #18 and #26 from the wireman for all my antennas. The trick for keeping them up is to use a Dacron rope for a messenger line that supports the very light wire. With the rope strung between the supports with a lot of slack, I attach small rings of gray PVC pipe. A small loop of the rope is pushed through the ring and then the ring is passed through the loop. The antenna wire is hung in the rings with any feed line supported by the rope. The wire carries no weight. When the trees sway in the wind the rope can break. I just let it, but force it to break where I want. I make a loop with about 3 ft of the rope and tie it with a short length of cotton line. The cotton being weaker than the Dacron will break first allowing the loop to add about 3 ft of slack to the antenna. 73 John WA8KNE n0evh wrote: Wow, I have read this reflector now for about four years.

[Elecraft] KX1 temporally deaf
This weekend I ran some test at a portable site our club will use to demo ham radio to about 50 youths. We set up a Kenwood TS430, tuner and 20 meter dipole running on AC power. I setup my KX1 with a 33 foot vertical with 33 foot counterpoise on the ground. A third operator ran a DC-40 with a random wire on the ground. When I set up the KX1 I was copying a station in the MIQP near 7040. Before I could call him I heard a very load station on 7040 with lots of signal while key up. It was the DC-40. After a short QSO, short in both time and distance, I walked away from the rig for a few minutes. When I returned the KX1 had no audio out. I tried 3 sets of earphones and also confirmed the phones were working with another source. The KX1 didn't even have sidetone. I assumed I had a failure of the audio out stage and suspected damage when the TS430 tuned up at 100w on 20. I packed things up and headed home where I checked the schematic before opening the case. All that is common to sidetone and receive audio is the last audio IC and volume control. The XG1 showed a normal S meter reading with 1 and 50 microvolts. With the cover off I started touching parts around the input to the audio amp listening for hum. I got hum at the input of the amp. S meter and hum called for connecting an antenna. At first I was not hearing much but over about 30 minutes the receiver seemed to have recovered and I was able to work Tampa from Jacksonville on 7026 with no problem. I have been playing with electronics and radio for fun and profit for well over 40 years. I don't like things that 'fix themselves.' Anyone have any ideas what might have happened? Could a high RF level cause temporary deafness? Keep in mind, this is a KX1 that landed 9Y0X on 20 after only 40 minutes. N6VX operating - I'll never be that class DXer. 72 John WA8KNE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Strange: KXAT1: SWR goes up, but so does forward power?? +Baluns
Martin Some basic things that can never be repeated too often. Any watt meter will only read correctly when connected to the load it is designed for. The power readings of forward power must be made into a 50 ohm resistive load. Your 4.2:1 SWR could be 210 ohm (4.2 x 50) or 12 ohms (50/4.2). The dipole will show something in the ballpark of 50 ohms. When connected to 32 ft of 300 ohm feed line, your radio and tuner will see something close to 1500-2000 ohms which is out of the range of the tuner. A 40 meter dipole will not tune well on 30 or 20. Strange as it sounds using an antenna that is not resonant on any of the bands can work better than one that is resonant on one band. Try 25 ft of wire going up the pole and 16 ft of wire laying on the ground. connect both directly to the binding post to BNC adapter and let us know how it works. Don't worry about sounding like a beginner - I've been a beginner for over 40 years and still learning. 73 John WA8KNE Martin Gillen wrote: Hi, I recently built a W1CG low power balun (Guanella 4:1 two-core design). I'm pretty new to amateur radio and my on-air results were pretty confusing to me so I was hoping someone could help me understand what is or may be going on here: For these tests I was using an inverted vee dipole, each leg 32ft (64ft total length), fed in the center with 32ft radio shack 300 ohm twinlead, held aloft by a 20ft fiberglass fishing pole, with the ends held 6ft off the ground by fiberglass driveway markers. Rig was a KX1 with KXAT1 ATU. Forward power and SWR readings taken from the KXAT1 (ie. no external metering). I started by connecting the twinlead directly to the KX1 using a binding post to BNC adapter. I was able to tune the radio on 40m, 30m and 20m to under 1.5:1 SWR, often 1.0:1. Power out read as: 1.5W on 40m 3W on 30m 2W on 20m I then replaced the binding post to BNC adapter with the 4:1 balun. Now the SWR increased on all 3 bands: 1.8:1 on 40m. 3.2:1 on 30m. 4.2:1 on 20m. On 20m and 30m there was a noticeable attenuation of signals but 40m sounded fine. So... so far it looks like the antenna simply didn't need the impedance transformation, and has degraded all 3 bands. I gave up on 20m and 30m with the balun due to the high SWR. However the odd thing I noticed was that the forward power reported by the KXAT1 on 40m had increased to 3W! So... I established contact with a station and asked him how my signal sounded with and without the balun. Here is the summary: Without Balun: KXAT1 SWR 1.0:1 KXAT1 Forward Power 1.5W Signal report: 579 With Balun: KXAT1 SWR 1.8:1 KXAT1 Forward Power 3W Signal report: 599+ I switched the balun in and out a few times to accound for fading. So I am left confused. Why did the SWR go up if the forward power also went up? My working theory is that the antenna fairly well matched already on all 3 bands but unbalanced. Adding the 4:1 balun had two effects: (1) Impedance transformation (2) Balance the transmission line ( dipole). The impedance transformation wasn't actually required and actually placed the impedance outside the KXAT1 matching range on 20m/30m, and degraded the SWR on 40m, but the balancing of the transmission line meant more energy radiates from the dipole elements and not from the transmission line. So the data seems to be telling me that this antenna could really use a 1:1 balun. What am I missing?? :) 73 Martin. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KX1- 80m and random wire
Until I get the KX1-8030 installed this is just speculation - so FWIW. I have ordered the Altoids Longwire Antenna Tuner from www.qrpkits.com. For $30 you get a small L network tuner with a max 16uh and 270pf. As is, the cap is only at the output end, but that can be made switchable to put it at the input side when needed. If the KXAT1 can't tune my antenna on 80 I will try the ALT as a 'pre-tuner'. 73 John WA8KNE Pierre Desjardins wrote: Hi Elecrafters, For field operations with a KX/40.30.20m, I currently use a 28 feet random wire at the end of a 22 feet pole, and an single 16 feet radial on ground.

[Elecraft] KX1 without the 30m board
N6VX has my KX1 and has worked 3Y0X on 20. When he said he wanted to try the same on 30, I informed him my KX1 did not cover 30. His reply - I've been working DX on 30. Seems he just enabled B30 menu option to see if it would work. Output was 3 watts, same as 40 20. The receiver was not as sensitive but was 'good enough' to work a few DX stations. Without the 30m or 80/30m board you will have low sensitivity and I have no idea what the output looks like on a spectrum analyzer. I plan to get the 80/30 board as soon as it comes out, but in a pinch this just might work. If you have a KX1 and the right test equipment, let the list know how well this works.

[Elecraft] 3Y0X with KX-1
I loaned my KX-1 to N6VX to take a shot at Peter I. Rob is my brother-in-law, retired with more time, more antenna, and lots more skill at CW DX than I ever hope to have. He got the KX-1 late Monday and sent me this email Wednesday morning. We hope to have the QSL at FDIM. John WA8KNE == Hello John, They were not on 20m CW yesterday, but we worked them on 14.023 mHz at 1358Z this morning with your KX1. The propagation was not the best, with the path going downhill, but, after about 40 minutes, they did come back to N6VX/QRP. Hope we show up in their log. Will mail the QSL card request today. Decided that I wanted just a few more bells and whistles, so I changed my Elecraft order to the K1-4B.

So here goes mine along with some background. In the early 70's I had and instrutograph (sp) that used paper tape to send code at any speed you set the motor drive to. Much like the computer generated code practice today. I made an offer to make code tapes for anyone that sent me a cassette. A high school student call and I became an Elmer via telephone. After several months of learning the code from the tapes I met him in person and gave him the novice code test which he passed with a perfect copy. I was not required to test his sending but I had a CPO and key with me and had him try sending for his very first time. What he sent sounded like it was machine sent. It was the only code he had ever heard. He passed his novice, upgraded and kept his first call for over 30 years. He also started with QRP and has stayed with it. My point is don't buy any key until you know the code and can copy with out effort at over 10 wpm. Only then buy the paddles and keyer. There are far too many people who think the know the code who should be forced to copy their own sending.
