[Lowfer] Wms is back on

Tue Apr 21 10:13:25 EDT 2009

I kept it off longer than I intended, while playing with my SDR. 
I see about 3hz total shift from daylight to dark. I am using a simple
 circuit with a 6.0mhz
microprocessor xtal. I used fixed npo caps in the osc-circuit , so without
 a trimmer I would
have to change caps to a smaller value to raise freq to the target 187.5.
 Off by myself this drift 
is tolerated. I have the Norcal DDS and I have been looking at the
 Pongrance dds which is a bit 
cheaper, I think Charles (CV) has one of those. Next transmitter willl be
 a two part with DDS inside
controled environment and final out at the tower with the b+ duplexed out
 the cable. I would like to
move to the watering hole but I am not sure the loading coil will tune
 down to 185.3. I removed some
turns to optimise the coil for 187.5. Like Scarlett O'Hara I'll worry
 about that tomorrow.
Yesterday I rearrainged the shack so I can get three computers on the
 desk. I have to use two with the SDR
one for controll and one for ARGO. The other is for ARGO with my TS50.
I did not see WEB past this week. I was hoping for some copy so I could
 check the desense from my beacon. No luck with
CV either. Last year I was copying WEB up till the first of May. Bill said
 in an email a few days ago his antcurrent is down
about 25%. Mine is up about 10% or more with the wet weather we have been
 having.
I did hear HI hifer beacon Monday at 0830local time(1730utc) first hifer
 I've heard since Jan. I copied HI audibly about
439. I wonder if MP, GA NC and others are still on?
If the underground critters will leave my power cable alone I should be
 able to keep the beacon on this summer. It will
be interesting to see how the propagation is.
Thanks for the report

Paul,  

Thanks for putting WMS back on the air. Picked it up in NE IL about  
0745Z at 187.4915 kHz and by 0830Z it had drifted down to 187.49153 kHz.  
Don't think the very slow drift was on this end because later, when the  
watering hole at 185.3 kHz was tuned in, MP was steady. Probably an  
oscillator just settling in after being off. Logged a new NDB source,  
ATA in Atlanta, TX on 347 kHz, earlier in the evening so expected to be  
able to copy WEB also, but didn't. Didn't copy CV either, but that was  
perhaps too near local sunrise anyway.  

73,  
Garry, K3SIW, EN52ta, Elgin, IL
