Hi Alex and group,

thanks for the post-processing and the reports and compliments for your good  receiving setup.

As a wrote before, i didn't  expect such results with my small antenna. Looks that the "cage" is able to increase the current at the feed point more than the antenna  having double height but without cage.

I will try to improve dimensions of the antenna for the next autumn in order to attempt 2way qso's (may be WSQ2 ?) .

73, Domenico iz7slz

Hello Graham, Group

I'm using audio from OPERA 1.4.5 to modulate my USB exciter setted to dial 136.000 kHz . So QRG seems ok. I got,  during last night, three decodes from SV8RV and many others from Markus DF6NM in OPDS32. Many thanks to these receiving stations.

Tx power out  is 50 W and antenna is very small: so these results are more than expected for this season.

I will stop activities for a week. Planned an holiday week with family in PA, OR. I will reactivate the trasmitter at the end of August.

73 and good holidays to all.

Domenico, iz7slz

Ok Domenico 

 

I don't  see  any  decodes  from  sv8rv-1   , with  coverage to  LA , would  of expected sv8  no problem ?

 

assume  qrg  is ok ?  latest  Opera   uses  1500  Hz audio for  all  bands  , that  makes  137.500   +/-   carrier ,  how are  you  keying  the  tx  ?

Yes Graham,

thanks for observing my spots.

from the end of July i'm QRV on 2200m with a small transmitter.

Antenna is  inverted-L. Vertical radiator is 8 meter long surrounded  by a "cage" of 6 wires all connected in parallel.

This fat antenna, requires a coil of about 2.5 mH.

So far i got some wspr-15 spots from SV,D,LA e since yesterday i'm trying OPERA with the hope  to be received at least from SV.

73 to all  group

Domenico, iz7slz
