I would like to hear from those who have built this receiver and why they made the choice they did. Larry, I've used the 170 kHz (that's what you'll actually get) VFO span on my K1 for the last five years. With the small mod described below, I find it very easy to control. It allows me to cover all of the 40m CW band, and to get 10 MHz WWV on the 30m band. It also allows coverage of most of the CW portion of 15m, which will be more valuable when the solar cycle starts to pick up again in a few years. You'll be able to tune about 20 kHz into the lower part of the 40m phone segment. Since the K1 receiver always functions in LSB mode, it would be possible to have cross-mode QSOs at the lower end of 40m, should the need arise. You will get responses stating how quickly the K1 tunes with the larger span, but 17 kHz/turn is *not* a very rapid tuning rate. What I think most of these folks are actually experiencing is a problem that results from the the VFO potentiometer shaft having very very little resistance to rotation. It is very easy to cause unintended dial adjustment as you remove your fingers from the knob. With a 80 kHz span, the effects of this are far less apparent. The solution is simple. Get a sheet of thin felt material and cut several circular, holed, washers which can be laid around the VFO pot shaft, between the back of the VFO knob and the front of the panel. Add just enough layers until you get a very slight resistance to motion, while the knob still remains easy and smooth to turn. Then it will be very easy to let go of the knob without introducing unwanted changes. I would never go back to 80 kHz. 73, Mike / KK5F K1 #175 Thanks for the info. With what you have said along with other responses I am going to set up my K1 for 170 kHz.

Re: [Elecraft] K1 VFO range
I built mine originally for 80 khz. With the bands changing and wanting coverage past 7080 on 40 meters, I redid mine for 150 Khz. It is a bit toucher to tune now but much better coverage. I have a 2 band card I built for 160 and 80 meters which resides in my K1 with the coming of good conditions on 160. 73, Sandy W5TVW - Original Message - From: Larry [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Friday, September 29, 2006 5:33 PM Subject: [Elecraft] K1 VFO range | I am building the K1 with the 4 band filter board.

[Elecraft] KX1/pm in the Garden
This morning i will be out enjoying the scenery in the famous Garden of the Gods Park in Colorado Springs, CO. i will be on 14060 +/- using my KX1 with a 10 foot whip while out hiking around the park. 9/30/06 Op times estimated to be 1615 to 1700z. Paul w0rw/pm The Garden of the Gods Park has an abundance of plant and animal life thoughout its 1,340 acres, 8 miles of trails, as well as the magnificent red sandstone rock formations, for which the Garden is best known. Many of these were generated by really big earthquakes and sculpted through time by erosion. The park is very popular and has about 1 million visitors each year. Maybe you have been there, can you remember the Kissing Camels, Balanced Rock, Ship Rock, Praying Hands, The Scotsman, or the face of Chief Manitou on the side of Gray Rock? i will have a special 'GOG' QSL Card available, This is the most beautiful park in the State of Colorado. For more park details on line see http://www.gardenofgods.com/parkinfo/ or http://www.co-trading-post.com/tp_html/gar-hist.htm W0RW/pm/KX1 will be Pedestrian Mobile (Peripateticus Mobilus Elecraftus) hiking around in the park using a 10 foot whip and a 13 foot counterpoise. There aren't too many overhanging trees to snag my antenna so this should be 'a walk in the park'. i will be using the great 300 foot tall granite monoliths as reflectors to the east and west as i walk around. i will be totally powered by those exploding Sony LiIon cells.

[Elecraft] K2 weird behaviour when receiving through SSB filter
Guys, Here a problem I don't understand. K2 # 3612 with: NB SSB 20W intrnal tuner The problem: When listening on SSB filter OPT1, 40m band and antenna connected, a bit of bandnoise is present. The S-meter is on S 5-7 or so with no signals around. Signals are clear. When they are strong the S meter functions as it should with those signals. With no signal meter drops back to S 5-7. Switching in the the other filters (width 2.12, 1.87, 1.78) at that time (no signals present) makes the S-meter drop to S 0-1 and bandnoise is more audible and S-meter flickering on QRN and so, as it should I think. It seems that something is triggering the AGC when I switch in the OPT1 filter, but I cannot figure out what it is and why. The funny (?) thing is that if using the OPT1 filter, the s-meter reacts to switching off the pre-amp and switching in the attenuator (as expected) Disconnect the antenna and the s-meter also drops to S 0. I've taken out the NB and the tuner: no change in this behaviour. Sure in need of good advice. Thanks in advance.

Re: [Elecraft] KX1/pm in the Garden
I worked Paul for a 559 from his KX1. I was running my KX1 at 2W into a hamstick on top of the car, parked at the Winterlodge Skating Rink in Palo Alto. I gave Paul 539. There was some QRN from nearby machinery. If you do a Google image search on garden of the gods my pix are the first hit.

The program MorseGen on my website will generate MP3 practise files at up to 60WPM. It's free, but you are welcome to donate if you feel that programmers deserve to eat. Julian, G4ILO.

[Elecraft] Gamma Research Very Small Switching Power Supply
Just got my October issue of CQ and saw a review of this very small power supply made by Gamma Research, model HPS-1a. It is 3.37 X 1.55 X 5.25 inches, rated at 13.8 VDC, 22 amps at 25% duty cycle and 5 amps continuous, and weighing only 1.25 lbs. If you do not get CQ, then the company's web site (www.gammaresearch.net) provides information. Has anyone tried this with a K2/100 rig? 73, Henry - K4TMC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

It is the MFJ-4125 which is rated at 25 Amps all the time and it SAYS no noise on all Ham bands, and it sells for $100.00. Your power supply doesn't even mention power supply noies. 73 Karl K5DI ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Power supply?
My Elecraft arrived! It's so new and shiny, I haven't even found the serial number yet! Happy happy happy! Joy joy joy! Now to power the thing... Any recommendations on power supplies? I've got a 12v power supply for a pair of powered speakers...is this sufficient for assembly purposes? After all, I can't operate just yet. 73, (just learned what that means...n00b) -- Justin C++12 Croonenberghs ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
