Yes, Laurence, I notized it=2E

hoping your new loop will work well=2E

Happy new year all=2E

Uwe - I ha= d a spoiler carrier up in 8270=2E02 to confirm rx stability for a while=

You'll see the screen bloom=2E I inte= nd to put up a separate active loop for 8=2E2kHz when the weather is mo= re tolerable and mod the input match to the original m0bmu amp/filter=2E=

My limitation are a noisy over head p= ower line some 200m away which I cant mitigate with the present tools=2E=

Anyone ID the carrier/mod on 29=2E7kH= z? Ive not put the df loop on it yet butit gets stronger at my dusk and= fluttery due to solar stuff during the daytime=2E=2E=2E

&nbs= p;

Strong carrier again Uwe,

I could not decode anything=2E The following carrier
measure= d 18=2E4 dB in one hour integration and the signal
calculator

http://abelian=2Eorg/ebnaut/calc=2Ephp?s= ndb=3D18=2E4&snbws=3D&snmps=3D3600&code=3D8K19&sp=3D10&= amp;crc=3D16&nc=3D2

says that should give Eb/N0 of about= 8dB=2E When I run the
carrier into the decoder it comes out well
vtraw -oa dj8wx=2E151229b=2Evt |
ebnaut -d -p8K19A -r240 -S10 -= PS -N2 -v -c1

initial reference phase 76=2E9 amplitude 2=2E991e-= 03
prep [ 0 0 0 0 0]
found rank 0 ber 2=2E4457e-01 Eb/N0 8=2E9 M = -1=2E063431501e-01 [**]
ps [ 0 0 0 0 0]
carrier phase: 7=2E5
c= arrier Eb/N0: 7=2E8
carrier S/N: 18=2E39 dB in 271=2E7 uHz
elapse= d 5

which agrees with the signal calculator=2E

With that = strong signal, the message should have been an easy decode=2E

So= , something is wrong with the modulation or bit clock=2E
If you tell= me the message, I can analyse the signal=2E

I have been checkin= g for your long carriers in very narrow bandwidth
at Forest VA (dist= ance 6667=2E7 km) but so far no sign of anything=2E
