Hello friends,

Thanks for your reports.

I have downloaded in Dropbox two pics of my small and ugly cage antenna and its capacitive hat.
Diameter of the cage is 2 m and lenght of horizotal wires is 8 m.  Impedance measured with rigexpert  is abt 45 -j2900 Ohm. This reactance value is also calculated by mmGal inverted-L simulation putting 2 meter as diameter for the vertical wire.
This is the same antenna that i'm using in MF with 0,450 mH variometer. In LF a second coil of 2.5 mH is added.

For Graham: sorry for confusing regarding sw version, i meant that i'm using  the latest. 

I will reactivate the transmitter as soon i come back from one week  holiday.

73 to all.
Domenico, iz7slz

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
