Re: recordings of KNX 1070
Hehe I figured it wasn't quite as strong. ;) I have yet to log 590-VOCM at home, and being 7.7 miles east of 5kW IBOC 600-KOGO makes it even more difficult. Maybe the new PL-606 can do it, or would a 9' PVC loop have the selectivity to notch out KOGO and its IBOC, yet be able to tune to, say, 591 or 592 and hear VOCM in 1 kHz or 2 kHz mode on the PL-380 (or PL-606)?toggle quoted messageShow quoted text
Also, IIRC, one of those recordings has the KNX traffic sounder in it, which I think could be used as an aid in identification for DX reception. (Don't know that my near-S7 signal in the middle of the day would qualify as "DX":).)

The KNX signal when in, was all by itself alone on the frequency but when the fading started , it mixed with another station. The signal itself was very readable but definitely didn't have the punch and volume obviously compared to your recordings. The station's distance from us is 3450 miles or 5,556 kilometers
St. John's, Newfoundland
Puyallup, WA Ultralight TP's for 11-13
Asian propagation this morning rebounded very nicely from yesterday's mediocre results, providing TP signals that were pretty vibrant-- especially in consideration of the elevated solar indexes. As such, results here were much closer to Steve's positive version.
Both "big gun" and second-tier Asians sounded very healthy around 1400, and it was a scramble to check them all during sunrise enhancement. Both 828-JOBB and 972-HLCA had their best signals of the season, as did 738-HLKG. 585-JOPG was unusually strong, along with 675-VOV and 756-CNR1. The Chinese lineup on 918, 927, 936 and 945 all were in audio at some time this morning, along with the Asian regulars on 603, 648, 657 and 666. A mystery co-channel on 639 was briefly dominant over CNR1 around 1455 (not // 594 or 1134), but co-channels on 972 and 1377 seemed to get lost in the "big gun" audio. Overall conditions were very favorable, but other than the 639 UnID no new or rare Asian stations were heard. Sick-sounding transmitters were back with a vengeance, though-- 738-BEL2's throbbing hum seemed to consume most of its modulation at times, and 657-Pyongyang's high-frequency audio seems to be missing. In relation to this, about the only surprising reception this morning was apparently hearing the infamous Pyongyang tirade-yelling OM and YL team on a vibrant 648-VOR at 1505 during the Korean program, with their distinctive rapid-fire shouted Korean. Hopefully this was just an aberration, and not an indication that this very noxious programming is really part of a new 648-VOR schedule.
The following were heard on a C.Crane SWP Slider model (7.5" loopstick) inductively coupled to a 9' sided PVC tuned passive loop (in the back yard). A modified ICF-2010 (30" loopstick) was used as an SSB spotting receiver:

Re: Is there an #ultralightdx IRC channel? #ultralightdx
Hi Stephen, it seems as though chatrooms have lost the popularity they held a few years ago. I use to own and moderate a chatroom for a different hobby. Use to have some good crowds (10-15 people) and some good times chatting. But the users slowly lost interest and dwindled away. The room sits empty now, don't think anyone has been there in the last year.toggle quoted messageShow quoted text
I'm still in contact with some of the friends I made there via AIM, but nobody seems to be interested in a group chat.
Now I wouldn't mind joining an Ultralightdx chat as you suggest, but I'd prefer it not be policed as tight as you suggest. Sure, we don't want it taken over by people using $100,000 radio systems and antennas, but I wouldn't want to be "kicked" just because I want to discuss my PL-390 or mention what I heard on my Ebay $75 beat to heck Sony 2010. :)

Re: ferrite vs sensitivity
I'm still on my quest to simulate ferrite loop antennas, this time for their signal to noise ratios. I hope I'm not proving that 17 swallows are as strong as a horse with all my graphs. Experimentation and actual DXing comes next I promise.
Let me point out a few simple design observations that I gleamed from the graphs.
First, use as many turns as possible without making the Q too high. My Sony ICF-S10MK2 apparently uses a small loopstick with an inductance of 650 uH. That is more than enough turns I would think. 300 uH is probably sufficient too, maybe lower. Having a good number of turns puts you into a kind of linear region where increasing the length of the rod improves the SNR the most. While increasing the number of turns on the loop does improve the SNR, best results come from increasing the length of the rod.
Second, increasing the diameter of rod does not improve the SNR that much, unless of course your rod has a very small diameter to begin with. It appears to be better SNR-wise, and less costly, to simply increase the length of the rod rather than its diameter. In addition there appears to be, for a given rod diameter, a maximum rod length beyond which no increase in the SNR occures.
Now here are the graphs. First for a ferrite loopstick antenna with an initial permeability of 125. One graph plots rod length against turns and the other plots rod diameter against turns. For a loopstick with a diameter of 12.7mm the best length seems to be between 200mm and 300mm FYI.
Next, here are the graphs for a loopstick antenna with a mu of 800. The best length for a rod with a 12.7mm diameter seems to be between 300mm to 450mm.
Ps. Just to be sure I haven't made any glaring mistakes here is the Matlab/Octave function I used to calculate the signal to noise ratio.
% mui: initial relative permeability of the rod
% n: number of turns
% lr: length of rod in mm
% dw: diameter of wire in mm
% f: frequency in Hz
% E: E-field in V/m
function [ snr Rac Rdc ] = loopstick (mui, n, d, lr, f, dw, E)
Kb = 1.38e-23; % boltzmann constant
T = 293; % room temperature 20C (293K)
muo = 4 * pi * 1e-7; % permeability of free space
sigma = 5.96e7; % conductivity of copper at 20C (293K)
B = 3e3; % bandwidth (3 khz)
lw = n .* pi .* d; % length of wire need
delta = 1 ./ sqrt(pi * muo * sigma * f); % skin depth of wire
Rdc = lw * .001 ./ (pi / 4 .* (dw * .001).^2 * sigma);
Rac = lw * .001 ./ (pi * sigma * delta .* dw * .001);
en = sqrt(4 * Kb * T * B * Rac); % noise voltage
mu = 1./(1./mui+(d./lr).^2.*(log(lr./(d/2))-1)); % rod relative permeability
a = pi / 4 * (d * .001).^2; % rod winding area
es = 2 * pi * n .* a .* mu * E / (3e8 / f); % signal voltage

Is there an #ultralightdx IRC channel? #ultralightdx
Is there one that regularly features members here? I've lurked some in #mwdx, and am thinking I'd prefer to IRC with DXers that are, so to speak, more my size. :) For example, they're using things like Perseus SDRs, 1000' beverages, Wellbrooks, phasers, etc - things that IIRC the cost of ONE component in their setup would exceed everything all of us ultralight DXers have ever spent on ultralight gear and antennas in our lifetimes, combined. Not to mention they have leadins to their antennas and can use them remotely, and aren't inductively coupling their radios' ferrite loopsticks to their antennas and using the radio right there at the antenna.
Naturally, they seem to have such superior equipment to mine that at local noon it seems they would be able to clearly hear TAs on 639, 711, 810, 999, 1071, 1089, or 1530 while climbing KFI, KIRO, KGO, KOMO, KNX, XEPRS, or KFBK's tower(s), or TPs on 711, 720, 810, 1080, 1089, 1170, 1180, or 1521 while climbing WOR, WGN, WGY, WTIC, WBAL, WWVA, WHAM, or WWKB's tower(s). By comparison, my equipment would only be capable of hearing those locals, they'd be leaking into the FM band, and would just barely be detectable about 10-15dB below the noise level even on their assigned frequency.
So where's the #ultralightdx channel? It's not on StarChat where #mwdx is - I tried joining it and ended up creating it temporarily, and I'm not up to operating a channel. I just would prefer to chat with DXers more my size - ones that use equipment that doesn't have SSB, the radio including external physically connected components is under 20 cubic inches (an inductively coupled antenna wouldn't count toward the limit, but a slider loopstick would), and the radio, including modifications and external antennas, cost no more than $100 total. ;) Of course I know there's this group, but it's not exactly real time.

Re: Oklahoma TP's 11-13-10
Thanks again for your detailed report using the PL-310 and 7.5" loopstick, and sorry that TP-DXing conditions weren't better for you. The sun must have gotten its act together after 1330, since we had pretty strong Asian reception on the west coast this morning.
<< 657 unID (KRE?), 1312-1313, barely audible unintelligible audio, fading away; slight het at 1323. >>
99% of the time, a TP on 657 kHz is the "big gun" Pyongyang BS (descriptive name) transmitter from North Korea, having a ragged-sounding carrier with frequent modulation issues. Standard programming is angry Korean tirades and obsolete music. If a DXer is extremely lucky, this noxious signal will be pushed aside by 657-China (Henan), a relatively sane-sounding station.
<< 702 unID, 1229, carrier; 1320 barely audible fading away. Still a mystery? >>
As you probably know, a pure 702 kHz carrier is almost always one of the Japanese NHK2 synchro stations, while a ragged carrier is about the same as a station ID from the (North) Korean Central Broadcasting station. It's the only ragged TP carrier on 702, and seriously off-frequency (on the high side).
<< 891 unID, 1239, slight het heard until KLTR 890 s/on at 1245. >>
On the west coast 891 is usually JOHK in Sendai, Japan (// 594), but Thailand and China are also common during good conditions. During this modest fall season, 891 has almost always been JOHK here.
<< 657 unID (KRE?), barely audible unintelligible audio >>
Every veteran TP-DXer knows that even when 657 is highly audible, it's still likely to be highly unintelligent.
