Allen & DIane... very nice DXing. There is one problem, that is not apparently your fault. The 1360 kHz Log for WTIC is really 1360 WDRC Hartford, CT. Checking your time/date this may be due to a

Scott et al; I have always thought the root cause of birdies and other artifacts like described formerly were due to poor shielding/grounding forming a loop circuit. I would like to add that in some

I've been advised KDIS - 1110 will be OFF tonight (Monday 22 November) from approximately 10pm-midnight PST, for engineering work.

Holy WOW, Allen and Dianne, that's a pretty impressive log! It's really amazing what these little receivers can do when they're set away from big cities, with all their attendant RF. I didn't know

Hello All, Asian results here this morning were not muchbetter than those experienced inland by Richard and Bill, and probably not up toNigel's level. The dreary results have been pretty common

This is getting ever more fascinating! I think all the suggestions to date are relevant, possibly to different degrees in different receiver configurations, AGC evidently being the common

If the radio uses LEDs for the dial light, they give off RF noise. Does it last just as long as the dial light is activated after tuning? Just a thought.-FARMERIK

Hello to All, As previously mentioned, here are the logs of the stations heard during our Mini-Dxpedition effort at Old Perlican,Newfoundland Nov 20 -21. Old Perlican is situated 102 miles from St.

Hi everybody, Unusually good reception to the north on Sunday. After logging two new WI stations it hit me. I pulled out my WI station maps and started going up the dial picking off a good number of

Last evening I was surprised to catch a new station. What's surprising about it is that it was on the same freq as one of our semi-lcl pests, KNSS, Wichita, on 1330. Logged this on my Eton E-100

It is unlikely this problem involves the Si4734 AGC. There is no threshold used in the AGC processing of the IF signal. The time constants are very fast and the only artifacts of AGC I've heard are

Very few, weak TP signals observed here this morning. Listening with the Tecsun PL-310 & 7.5-inch loopstick, at 1203-1322 UTC, I only heard weak carriers on 594, 648, 774, 828 & 972 kHz. The

I wrote the correct calls in my logbook...just hit a "K" instead of "J" when I posted. Yawn! :) Tim, KD8GZ

These observations taken together do seem to suggest that the chuffing (I, too, use the term "pumping") is audible AGC response, either triggered by seepage from other circuitry, such as the

Greetings to All, This past weekend Dianne and I traveled to Old Perlican, Newfoundland where we not only attended a family function Sunday, but also took to the dials in a mini Dxpedition with the

Hello All, It's great that Nigel noticed some exciting Asian signals this morning,which certainly was a better result than the west coast seemed toexperience. Thanks also to Nick for his comment

Ah, that chuffing! I call it pumping, but whatever you call it, my understanding is that signals that fade in and out below a certain SNR threshold (10 dB?) cause the AGC to pulse on and off. I

Im stabbing in the dark, Kevin, but I wonder why the backlight would cause this - of course, there will be some 5sec timing circuitry which could be the culprit. This, or other processing, could also

My recollection was it was indeed an AGC problem, but I'm certaily not an expert on the circuitry. IIRC there's a threshold level of the AGC that causes problems with weaker signals. Hopefully someone

Hi Michael/all: I think the chuffing refers to the chuffing sound of the "hash" created by the backlight of the display? On mine, it "chuffs" for about 5 seconds every time the backlight comes on
