Anyone know anything about a beacon identifying as EY9 followed by a 3 seconds keydown? It's on 1812 since about 8 minutes ago... 73 - Eric NO3M _______________________________________________ UR RST
System similar to what you mentioned regarding the gain compensation/distribution, HPF/BPFs, RX overload, PTT, and additional signal path sources and output routing (incl. looping back): http://no3m.
Also check what might be available from the Wireman. I picked up a 5000 ft spool of twin-lead (#18?) from them a couple years ago for $100. It was a bit of a job splitting it, mainly from the tendenc
East from near Erie, PA. No SE antenna to try, so can't determine if the signal favors that direction from here or not. Freq. is 1810.53 when zero-beat in CW, but does not seem particularly stable, m
In case anyone is interested in constructing a switchable 8-circle based on the BSEF array, W9RE's PCB is laid out with provisions for Magic-Ts and step-up auto-transformers where applicable, also th
The method I have used is similar to what Tom details in some respects. The main RX is fixed in a prime direction, usually NE and later W. However, the sub-RX is typically on auto-scan between transm

For anyone interested, I will be streaming live audio during the Stew Perry contest tonight. URL: http://audio.no3m.net/ Click on the M3U link in the upper right of the box to start listening. Stream
Not sure I follow your logic. Maybe I didn't make it clear in the original post that I am operating in this contest, so the radios aren't just going to be sitting idle providing people with "remote r
Since there seems to be too much concern over this, though no ill intent was intended, audio will not be broadcast. GL / 73 Eric NO3M You made it clear what you were doing, and I am quite sure Clive
ON4UN describes a method of "over swamping" the base of the topless verticals used in his four-square receive array. On 80M, he switches in additional series resitance to arrive at a total feedpoint

Several Amateur Radio operators will be running Part 5 experimental 630M CW beacons during the ARRL Field day event: WD2XSH/20 (op N6LF), 20W ERP 475.0 kHz OR WG2XKA (op WA3ETD), 1W ERP 472.5 kHz VT
-33 is the lowest I've personally decoded, been decoded, and have seen between others. Currently running WSPR4 in Linux with a Microham MK2R+ (built in USB soundcard). 73 Eric NO3M / WG2XJM On 09/03/
Not sure what happened on your end, but I had you in the log, Jim. Sure, it was a struggle, but got your call and exchange fine after plenty of repeats. Guess we'll try again this morning! Back to it
For anyone interested in 630M activity, there will be several US Part 5 experimental stations (all Amateurs) running beacons, making QSOs, and possibly passing some NTS formatted traffic, primarily C
Thanks to all the topbanders that had a listen on 630M this weekend. Unfortunately, Part 5 U.S. experimental stations can only QSO with other Part 5 stations, so crossband QSOs would be prohibited. B

What I have found to work well is taking advantage of a radio with dual receivers, not necessarily "locked", ie. diversity as in the K3, but at least on the same frequency. The main RX is fixed on th
This past morning, loudest I've ever heard Jim's QRP on 160 that I can recall. Easy ragchew level. 73 Eric NO3M Yes, it was a good night. Dave, W0FLS and Toni, N0NI, are two guys who pulled my QRP si
