[Elecraft] re K1 construction:relays and VFO range
Good morning, everyone and thank you in advance. I have had smooth sailing up to page 37 of the Rev. F manual. 1) In the lower right corner of the page the instructions are to tap BAND twice...to change to the next band...and then two or more times to return to 7.0 Mhz. I am setting the radio up for 20 and 15 M. When I follow the instructions the display, which opens up with E42 as expected, switches between 14.0 and 7.0. There is no 15M display. The relays click and are well positioned and what I think is pin 1 and 10 of each relay show continuity while in the circuit. Should I be seeing a frequency for the 15 M band? 2) What issues arise if the VFO is set for 150 instead of 80 kHz?

RE: [Elecraft] re K1 construction:relays and VFO range
Bob, The K1 does not yet know that you have configured the board for 20 and 15 - that is why you see the display for 40 and 20 only (these are defaults in the firmware). You will set the proper band using the menu a bit later when you get to page 39 and do the band assignments. The only issues that I know about in the selection of 80 or 150 kHz range for the VFO is that the tuning rate will be about twice as fast with the 150 kHz range compared with the 80 kHz range - most folks seem to like the 80 kHz range, but it is matter of personal choice and operating preferences. 73, Don W3FPR -Original Message- I have had smooth sailing up to page 37 of the Rev.

[Elecraft] Scratches
I found an old Radio Shack amplified speaker in my junk box and decided to hook it up to the K2 for some extra added punch. It fits nicely on top of the K2 but I was wary of scratching the finish. So I applied to the bottom of the speaker, several of those round felt pads that are meant for the bottom of furniture legs. No more worries about scratching the K2! 73 de Larry W2LJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

3M makes some small adhesive-backed feet that can often be found in the cabinet hardware section of a home improvement center like Home Depot or Lowes. A similar product is smaller felt pads that attach to cabinet doors to keep them from banging when closing.

[Elecraft] inoperative KNB2
My KNB2 noise blanker doesn't appear to work hardly at all. It never has worked well since I built it. I recently downloaded some notes that Gary Surrency sent to K0WA. Gary's comments include the following: You can check to see if Noise Gate Q5 is blanking by touching a resistor of 1K - 2K to the base of Q5 with the other end connected to +12 volt source. This should turn on Q5 and result in a large loss of signal... I did this but I only got a slight reduction in signal. Does this indicate that Q5, PNA is weak and should be replaced?

[Elecraft] Amplifier T/R Keying problem
I have a problem trying to key a homebrew amplifier with my K2 (S/N 5251). I am using the two-transistor T/R circuit from the Mods web page, and the T/R relay pulls in as expected, however there is an annoying thump in the received audio when the T/R returns to the receive state. I am using the separate receive antenna (Rx) input. If I disconnect the receive antenna line from the amp, there is no thump. If I trigger the T/R relay driver circuit manually, there is no thump. It seems that there is some interaction between the receiver unmuting and the T/R relay going to the receive state simultaneously that causes this thump. Any experience or ideas?

Drawing on a graphics pad, note taking, to do lists, etc all in one searchable (via many pathways) database. Very, very easy to use. Very intuitive. I am synchronizing it between all of the computers I use on a daily basis (six ?) as I travel about at home and at work. The version I am using is the free one. There are many more options in the for pay version. Kevin.

[Elecraft] WB3AAL's Butternut HF9V Project Update
Hello, Today I took off my 160 meter coil from my ground mounted Butternut HF9V. I also added more radials onto the system, total of 24 radials now. I plan on buying a DX Engineering Radial Plate and add more radials to the system, hopefully a total of 60 radials in all. Check out www.wb3aal.com for SWR readings, I am happy with the outcome. I still need to plant the radials in the ground but that will be after I have the radial plate in ground. 72 and Thanks, Ron Polityka WB3AAL www.wb3aal.com www.n3epa.org/ K1 - SN 01011 K2 - SN 01392 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KX1 Mod / EPS1 12V DC-DC converter - WORKS!
I got an EPS-1 DC-DC converter in a horse trade about a year ago and thought it would be a cool addition to my KX1 to jump the 9Volt internal batteries up to 12Volts. The EPS1 was either dead when I received it or I killed it because when I plugged it in to a battery source as the switching FET surface mount transistor caught on fire! It looked like one of those 4th of July snakes burning only with sparklies. I let it set on the shelf for a while and then tried a couple of times to resurrect it with no luck. I tried replacing the blown FET with a 2N7000 but it didnt work. I then ordered a new MAX1771 DC-DC converter controller chip and when replaced the one on the EPS-1 board with the new one it started putting out 12 volts with about 4 volts in. I experimented with load resistors and it was clear the 2N7000 switching FET would not handle the current so I swapped it out for a Radio Shack IRF510. The IRF510 didnt even get warm with an amp load so I tried running the KX1 off of the modified EPS-1.It worked great. I was getting 12 volts from a little 9 volt battery and was getting full power out of the KX1 rather than the lower output I get when running off the internal 9Volt batteries. I thought I could just disconnect one of the 4.5V AA packs in the KX1 and then put the EPS-1 inside of the KX1 but it turned out that 4.5 volts was too low to get reliable switching from the EPS-1. I then went to Radio-Shack and picked up a 4-AAA battery holder (RS270-411) which fits nicely into the space of one of the AA original battery holders.I removed both original battery holders and installed the EPS-1 where the other original holder was. It worked FB. I had to cut a small hole in the back of the case so that I could access the RS770-411 on/off switch and used double sided foam tape to secure the EPS-1 and battery pack. I have no idea how long the batteries will last. I do know that I have had the KX1 for a couple of years and have only changed the batteries once in that time so I imagine that they will last long enough for my use. Ill see. EMBRES no longer makes the EPS-1 but the schematic is pretty simple and comes pretty much right off the datasheet. Maxim-IC makes a litle MAX1771 evaluation kit that might be a direct replacement for the EPS-1 although I dont know how much it costs.

If you can fit one 4-AAA holder into a KX1, then you could also fit two of them in. With Lithium or Alkaline AAAs, you'd then have your 12 V at much better efficiency than you get out of the DC-DC converter ;) 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Elecraft CW Net Announcement
Good Evening, I slowly grow inured of my own cooking. I am regaining some of my lost skills though. One day I may even grow to like it :) However, I am eating well and getting used to cleaning the house, washing the dishes, and doing laundry. One of my radio friends wants to help me get a 2 wavelength 160 meter loop into the trees. I had to tell him to hold off since the precommercial thin is not yet complete. Once that is done I am ready to start stringing more wire up into the fir trees. With a tuner the loop should work from 10 meters to 160 meters with not much effort. Now if only I had a little more time to use my radio on the air! The weather has alternated from thick snow to very thick rain to a short burst of sun over the last two days. We only had five inches of snow so travel was not much impeded yesterday evening. The log trucks beat a path to within a mile of my house so Pat's car brought me home easily. The same could not be said for my truck. It needs new tires and a lot of weight in the back to make up for its lack of front wheel drive. Oregon snow is not like the snow I grew up with; it is very slippery since the temperatures barely get below freezing here let alone get cold. At forty below zero Fahrenheit (or Centigrade for that matter) snow allows one traction. I doubt it has ever gotten below zero here in the Coast Range let alone grown cold. Then the folks in Europe would not complain of our climate with their current cold snap. Hopefully that will break for them soon. In other news: we will be running the nets at their new times once again this week. Last week propagation jumped all over the place; especially during the forty meter net when Lloyd in Maryland was easy and Tom in Missouri was tough. Never can tell what is going to happen these days. Spring is on the way however and the sun is slowly returning to our latitude. I hope the bands treat us well tomorrow evening. With any luck we will hear Geoff from far off Scotland! Please join us: Sunday 2300z (Sunday 3pm PST) 14050 kHz Monday 0200z (Sunday 6pm PST) 7045 kHz Visit our web site: http://ecn.visionseer.com/ for further details. Thank you for the web space Dan. Soldering each evening this week :) Kevin. KD5ONS P.S. My fingers have yet to heal so the paddles may grow slippery tomorrow night. Please forgive the flinching and slipping in my code.

[Elecraft] Re: T1 and XV50
Hi Harvey, The T1 should certainly work with the XV50. In the T1 manual we mention a reduced tuning range on 6 meters; this is a necessary compromise to allow the T1 to be used on the lower HF bands. Losses may be somewhat higher on this band, depending on the reactances involved. You should use low power when tuning up the antenna, and be sure to keep power down to 20 W SSB/CW and 10 W AM/FM during normal operation. 73, Wayne N6KR Harvey Howell wrote: Does anyone know if the Elecraft T1 tuner would be a good tuner to use with the Elecraft XV50 transverter?
