Jay, Domenico, LF

now it's raining and the antenna current it's quite unstable.

Anyway, tonite I'll try another TX session with a new Spectrum Lab configuration.

In particular, I'd simply use the aux out as "quadrature output for I/Q modulator" instead external HDSDR program and without VAC:

The image rejection optimization isn't possible by software but it's already quite good.

So:

QRG: 137546.2 Hz

Coding 8K19A

CRC 15

3 sec./sym

7 characters

Duration: 30 min.

Every 30 min., 1st on 2200z, last on 0700z

Many thanks.

All the best

No decodes as you were outside of my receive range.

LF,

my previous  transmission's announcement was wrong.

Since i have run an obsolete setup file, the transmissions succeeded but on 137540.0 Hz  (instead of 137545.2 Hz) with 6

char, 3 s, 8K19A, CRC16.

I hope that receiving attempts can be done anyway. Sorry for the trouble.

I will send now, via daytime propagation, an 'hope' message on 137540 Hz, 38 characters 0.5 s/sym 8K19A, CRC16

at 10:30, 11:30, 12:30, 13:30.

Finger crossed also for that situation !
