[Elecraft] [K3] Flickering ALC/

Executive summary, intermittent connections in a trap vertical caused the ALC to go crazy. I suddenly had bizarre behavior when adjusting my mike level for JT65. When trying to get the ALC to be 4 bars it was all over the place. It was flickering on and off and sometimes the tones were modulate a

[Elecraft] BNCs

Don't know where anyone got the idea that BNCs made for RG-8x we 75 ohm. I worked in the tv industry for many years and we used hundreds of BNCs that were made specifically for 75 ohm video. By the way, RG-59 not RG-79. Now days I build hundreds of cables for RF out of rg-58 and rg-8x BNCs and t

Re: [Elecraft] K3 and VB6

All, While Joe's response will eliminate the behavior, I feel that a fuller explanation is in order. When a computer boots, it will "exercise" the RS-232 signal lines including the RTS and DTR signal lines. If you have your K3 set to do keying or PTT with those lines, you can expect the K3 t

Re: [Elecraft] K3 and VB6

There's also an annoying problem that in valves the comm port. Every time in turn on my PC, during boot-up, the K3 momentarily transmits. Is there a way to prevent that or every time I turn on the PC, do I have to turn off the K3? Set CONFIG: PTT-KEY -> OFF-OFF and the K3 will no longer respon

[Elecraft] K3 and VB6

A few months ago I was working on a Visual Basic program to control my K3. 2 days ago when I went back to do some coding, I had a problem where, when I opened the Comm port, the K3 would transmit. I tried sending the RX software command to the K3 but it didn't help. It was stuck in transmit! I'

Re: [Elecraft] HF noise.....30m

There's an 850 Hz RTTY station near the upper end of the band most evenings, fairly strong in N. Cal., which seems to be encrypted -- at least I can't print anything intelligible from it. It may be there 24/7 and fades due to daylight prop, don't know. I've also heard a couple of the Russian

Re: [Elecraft] K2 Keying mod Questions

Ken, The Elecraft kit for the K2 Keying Waveshape mod is no longer available because the small PIN diode to be used at RF Board D36 is no longer available as a leaded component - however an SMD solution is available, read on if interested. I do recommend that the mod be installed when the KP

[Elecraft] K2 Keying mod Questions

All, Now that I want to add some power to the K2 so that it could become a full backup station (instead of just my QRP contesting rig) I find that I may need to do some additional things to the rig. My K2 (serial # 455) does have most of the mods in it but one that I didn't do was the keying mo

[Elecraft] HF noise.....30m

Often on 30m. Starting arnd. 10115 & anywhere from 20 kc wide to out of the top of the band. A fast pulse. Only happens after dark in NA. I believe it's OTH radar. Of course no one has ever said it was theirs. My K3 doesn't block it as some nights it's 20 db over S9. Once in a while on 1012

Thanks to all who responded. The Chinese radar seems to fit what I hear best. I'll try to null it with my Pixel Loop (which, by the way, is a great, quiet receive-only antenna: ) On 12 Oct 2014 21:23, Merv Schweigert wrote: There is Chinese Hainan Island

Re: [Elecraft] Noise in the Mideast

There is Chinese Hainan Island radar that is very active, and usually on 7MHZ. it covers 100KHZ at least, the "smaller" 10khz wide signals are also radar, over the horizon, the smaller ones usually are several seconds of signal then space and repeat..the Hainan dragon is constant on all

Re: [Elecraft] Noise in the Mideast

There are a number of similar transmissions that sweep about20 or 40kHz but spread because of the short rise time of the modulation. These are over the horizon radar systems that on analysis appear to be very similar to those from 20 years ago. 73 Peter G3SMT On 12/10/2014 18:03, Vic Rosent

[Elecraft] Noise in the Mideast

Since getting on the air from Israel I notice an interesting noise on the bands 7 and 10 mHz and to a lesser extent on 14 mHz. It is a wideband 'schmutz' (technical term) which can take from 10 to 50 or 100 kHz. Its amplitude drops of gradually as you move away from the center. It reaches S9 le

Hey all, I have an analog scope, excellent in its day: http://udel.edu/~mm/tektronix/ If interested, please contact me. It's yours if you can pick it up. (Sorry for poor phone pics. Camera pics can be provided.) I also was given an old Heathkit scope, ca. '62, from the estate of an SK.
