[Elecraft] 10th Anniversary ARS Spartan Sprint Annoumcement

Members and Friends - This month is very special. It was 10 years ago that Richard Fisher KI6SN, Russ Carpenter AA7OU, and Wayne Burdick N6KR formed the Adventure Radio Society. The goal was to promote CW QRP in the out-of-doors. One of the most popular activities of the Society has been th

[Elecraft] K1 Problem

My new 4-band K1 #2183 has been finished and on the air just over a week now and has been working fine. Late yesterday when I switched to 20 meters it was dead on that band. The other 3 bands are working normally. I am going to have to do some troubleshooting when I get home from work today.

Re: [Elecraft] audiodistortions by DSP

Hi Manfred, Re-check the denoiser, autonotch, and filter gain settings in table #7 on page 37 of the KDSP2_A1 manual, and set your K2 to the default settings shown in table #7. If the problem is still there,, you might try reducing denoiser SSB gain and / or SSB filter gain below the default set

[Elecraft] ATU firmware update ?

I have a K2 with ATU f/w rev 1.03. Would there be any advantage to updating to the lastest ATU firmware ? Ken K1DWZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr. Change

RE: [Elecraft] ATU firmware update ?

Ken, I can't recall all the update features, but the one that I would deem important is that the newer firmware supports 60 meter use - however, consider that transmitting a CW carrier on 60 meters (even for tuning) is not within the FCC rules. I use a resonant 60 meter dipole myself. 73, Don W3

RE: [Elecraft] K1 Problem

Wes, I should think that the trouble would be found on the FL1-4 board. Check the 20 crystal first. Measure the RF Voltages with an RF Probe and compare to the normal ranges listed in the K1 manual. 73, Don W3FPR > -Original Message- > > My new 4-band K1 #2183 has been finished and on

[Elecraft] Audio Distortion by DSP2

There has been minimal user feedback given on preferred DSP settings. Try first setting the DSP2 to the Elecraft defaults found in manual table 7, if they are not currently set to those defaults. Try reducing the denoiser decay setting to 07 for SSB as previously suggested by a user. I have

[Elecraft] Solar Controllers

[Elecraft] K2 BANDS - How?

I've gotten K2 # 5422 - out of the crates, out of the hanger, onto the tarmack, and pushed out a ways, to Part III alignment. Thanks to superb help from "Scott", "Gary", "Lisa", "Don" and Elecraft Parts and Support groups - I've had a successful build so far! Can't say enough about both the exper

RE: [Elecraft] K2 BANDS - How?

Fred N3CSY asked: QUESTION: K2 BANDS? How does one know what "BAND" the K2 is set for? I know I can do BAND+ and BAND-, and I can do BAND+/BAND- frequencies entries. BUT HOW DO I (me) know - what BAND the K2 thinks it is in? There must be a base BAND spot - where all the ups, downs, and change

Re: [Elecraft] K2 BANDS - How?

Fred, Relays K12-15 switch the 8 VCO ranges. Once you have selected a range the LCD is your indicator of what band you are on. Because they are latching relays it will "remember" what band you are on. Having selected a band changing frequencies is a matter of turning the optical en

[Elecraft] Re: K2 BANDS - How?

How does one know what "BAND" the K2 is set for? Hi Fred, The K2 firmware does have a notion of what band you're on. The way *you* can tell (usually) is to look at the VFO frequency. However, it is possible to tune outside the normal band limits, possibly even into the next band's territory

RE: [Elecraft] K2 BANDS - How?

Fred, Look in the manual and on page 5, top of the second column, you will see the K2 'Frequency Ranges' listed. We commonly refer to those as 'bands' 3.5 to 4 MHz is the 80 meter band, 7 to 7.3 is the 40 meter band, ... 28.0 to 28.8 is the K2 10 meter band (the actual amateur allocation goes up

Re: [Elecraft] K2 BANDS - How?

Fred Welcome to the Elecraft club, membership lasts a long time! The K2 returns to the last used frequency when you power it up, other than that the bands just cycle round. Assuming you haven't set any transverter bands pressing down from 1.8 MHz takes you to the 28 MHz band, etc. Moving arou

[Elecraft] Disconnect FCTR probe after finished?

Last evening I read somewhat older artikel in this Elecraft Net. Is it true that it is better to disconnect your FCTR probe after filter aligments are done? My probe is still connected to TP2, this way I can always check/realign filter settings. But the possibility is that you can get some spurs

Early in K2 history, a number of builders found spurs that would go away if the probe was unplugged and stowed. Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (A

[Elecraft] QRPTTF from Wichita Mountains Wildlife Refuge

I'll be operating and camping in SW Oklahoma (near Lawton) for QRPTTF. Weather is predicted to be cool but with a good chance of storms - hopefully the tent will be waterproof and band conditions will continue to improve. I'll be using my KX1 and experimenting with a new type of battery. Details, p

The Alabama QSO part is this weekend and I will be on, along with several of my fellow ops from the Birmingham Amateur Radio Club. Most of us will be running QRP. We will be lurking about the lower 40Khz of each band 160 thru 10M. If you are interested google "Alabama QSO Party" for the ru

[Elecraft] K2 Alignment ACCURACY?

I've got the base K2 # 5422 built - and am doing the "Alignment & Test, Part III" - Receiver Pre-Alignment, Transmitter Alignment (page 74): The difficulty I'm finding: It seems like the whole testing and "peaking" adjustment, is based on BAR GRAPH 10-LED Display and tweaking the various L1/L2,

RE: [Elecraft] K2 Alignment ACCURACY?

Fred, You can use your ears rather than the S-meter - just tune for the strongest signal strength. Close your eyes and listen, you should hear a peak as you rotate the inductor slug (or capacitor trimmer). You should be able to resolve the peak within about 1/4 turn with just your ears. The pea
