Great Second Morning at Grayland
John and Guy,
Every time I take the Murata-filter-equipped E100 out to Grayland, its performance is amazing, just like John is experiencing. It not only cuts through domestic slop like a knife, but seems to boost up the S/N ratio even on DX stations in the clear. The CFJ455K5 filter makes a world of difference.
Congratulations again, John, on your outstanding Ultralight DX catches. It's kind of a puzzle why North Korea-657 hasn't showed up for you... that one usually comes in whenever CRI-963 is strong. But your long list of Chinese, Japanese and Koreans will be the standard of success, for Ultralight TP chasers this season. This is more fun than anybody ever expected :>)
73, Gary .

The conditions to Asia were much improved here this morning over yesterday's pedestrian showing, with the exception of North Korea, for some reason. I was at the dial at 1120 UTC (LSR=about 1320). It was pretty much all about China and Japan until exactly LSR, when the Asians faded some and the DUs came up. I pretty well skimmed the cream off Japan yesterday morning, but conditions were so much better this AM, that I received a number of second and even third level Japanese (5 and 10 kW) as well as much of the cream of China. Olympic coverage was widespread, being that our dawn coincides with prime time in East Asia and DU... and the games being located in China. The Olympics coverage made for some strange parallels, with 972 running some coverage // to KBS1 and even more unusual, several of the commercial networks in Japan were carrying the same Olympics JJ that NHK1 was carrying. Wow!
There were bunches of relogs from yesterday, though I tried to concentrate on new` stuff, naturally. The log shows 18 new Ultralight catches and one new country: Marshall Islands.

Most of the above are at least somewhat regular here at Grayland during the heart of the Fall Season (October) but I'm particularly pleased with the 1269-HBC Synchros, since there are only two: 1 kW and Obihiro at 5 kW. I'm also pleased with 1440 JOWF which was totally dominating 1440. Not unheard of here at Grayland, but pleasant all the same. Also
I tried the T615 Barefoot several times on signals that were particularly strong (972, 1566), even going outside once. No luck. Going TP Barefoot is REALLY difficult.
I'm sort of overjoyed , too, with 1179 and 1269. That Murata 5 kHz. is a wonder. I received those two by off-tuning one kHz.... e.g. when tuned to 1269, the station on 1270 was obliterating a barely audible HBC, but when tuned to 1268, HBC was in the clear. Very nice! A good filter plus 1 kHz. tuning resolution makes a heck of an ultralight.
I should note that I discovered a whole class of weak audio that the E100 can't touch. After dawn, in that happy half hour that only occurs at the coast, signal levels of all sort (including noise) drop away with daylight. At the coast, though, some DX hangs on or even returns for about 30 minutes. This morning, the DUs made their only appearance at and after dawn. There were about a dozen of them strong enough that I could at least ID the language; about half, I could follow the programming... all using the 313e. Only three of these very weak ones could be heard at all on the E100 + Wellbrook.
The Ultralight loggings of the last two mornings have been an embarrassment of riches.... about double the number that I'd hoped. I think that an awful lot of the success is due to an almost perfect match between the location (very low RF environment so overloading is not an issue and COASTAL) coupled with an excellent little radio that is being driven by a really serious major antenna. Another advantage that I'm enjoying is DXing at a site and season that I have done for 18 seasons and being particularly up to speed on the band due to the early appearance of Asians this summer at my home location. Finally, it is a distinct advantage to be able to DX several days in a row, unlike many of my NW colleagues who are not yet in the "post-employment years."
Speaking of days in a row ... I've two morning to add to my now 72 Ultralight TP loggings this season.

John, FYI, the Murata filter we love for the E100 is nominally 2.3 kHz, not 5 kHz. I am sure you know this...it was probably a slip o' the typing fingers.

In fact, it's a 2.4 kHz nominal filter (sez p05e9.pdf). This
one measured 2.9 kHz @ -6 dB:
Shape factor is about 1.4, not too shabby. It's not clear
from the catalog how many elements the CFJs actually have,
must be at least 9. Nice metal cased SSB filters in any case.
It was that plot you reference, by radio amateur KK6IL, that convinced me this filter is an excellent choice for upgrading my E100. A shape factor of 1.4 is *excellent* for a ceramic filter; this is more like the shape factor of the best of the expensive crystal filters such as INRAD models I have used, or the ICOM FL-44A.
The best crystal filter shape factors I know of are in the 1.3-1.4 range. However, top grade crystal filters are much too large to fit inside the E100, but the CFJ455K5 is *just* small enough to fit within the E100.
The CFJ455K5 is the same filter used as the narrow 2.4 filter in the larger Eton E1. Maybe that is why the E100 is so happy with this particular filter upgrade :^)
