Alberta TPs for 7 November 2018  View Printable Version 
Thursday, November 08 2018

IRCA
Definitely no goldmine out on the prairie. Still no sign of any
Asians, with just a few DUs coming in. I noted 612, 774, 792, 828, 891,
1026, 1116, and 1548 with audio around 1400 this morning.

73,

BOG question  View Printable Version

Nick -


Hoping I remember all the details correctly as I don't have time right now to re-read things....


Luis has put this data on the web before and claimed "resonance". Someone then educated him that current peaks and resonance are not synonyms,


My recollection is that the subject of current peaks was well covered and analyzed by Beverage in his 1923 AIEE paper.


I see no reference to Beverage's work so assume Luis did not explore that area. I saw no numbers to serve as a basis for "resonance" - some L and C values would be helpful.


But we stray from the original question : how much loss is there in a non-terminated BOG / Beverage? Some have compared "over the shoulder" versus normal wires, including John Bryant. Assuming I recall correctly, he found that over the shoulder had some feasibility as the loss was some 5 to 10 dB.

My experience today was similar to Nick's. A bit of a recovery, but
nothing spectacular. Reception was limited to the usual crowd, most of
them a bit below normal.

But, for the most part, it wasn't really hopping here, I'm afraid, at

for the first time here only a month ago, so that wasn't bad, but it
was "extreme minimalist DX" with a careful null of 650 and some
imaginative listening...pretty clear though with JOAK in one ear and
JOIG in the other.

We'll see what the files deliver. The first go round didn't seem to
have any Chinese, and there were a couple yesterday.

best wishes,

With


4.5 terabytes of hard drive space on my laptop now I decided to just let
SDR recording continue uninterrupted through the night.

Spot checks a few times through the night showed a wealth of TPs up and
down the band. When I stopped recording at 1645 UTC (nearly two hours
past


local SR), a handful of Chinese and Korean signals were still providing
weak but clear audio.

So... what a turnaround from the previous two mornings. I'll be
interested


to know others impressions of DX on Nov. 7th, as I face an SDR DXer's
dilemma of how to approach over 11 hours of productive DX recordings!

Hi Guy,

I'm glad that your TP-DX propagation improved greatly at Cape Lookout on the Oregon coast!

<<< So... what a turnaround from the previous two mornings. I'll be interested
to know others impressions of DX on Nov. 7th, >>>

First, a disclaimer. Propagation in Poipu, Hawaii routinely delivers a gold mine of exceptional DX daily, to the point where a DXers quickly starts to develop a spoiled attitude of entitlement. Northwest DXers who typically chase DX on local ocean beaches should definitely avoid this area, if they wish to continue feeling satisfied with the propagation and results at such venues.

Anyway, in answer to your question, 702-BBC in Oman apparently made a return appearance with Arabic around 1615, and 918-RNK (Cambodia) once again hit an S9 level with music shortly before its 1700 sign off. The 675/711 VoV parallel was easy to notice, but 675's S7 signal let up long enough around 1630 to let in a new foreign language UnID (with everything from Oman to Japan possibly in play). The Chinese propagation blasters on 783 and 909 both signed off suddenly around 1605 for no apparent reason, but I recorded S9 sign off messages from both of them. The ABC DU's were around at S9 on 612, 630, 702, 774 and others with the goofy call in talk guy, but fortunately he could be completely nulled just by turning the FSL away from him-- in which case the Asian TP's would typically rush in with powerful signals at S7-S9 levels. Anyway, Guy, you asked :-)
