Drive level is critical to success; don't over drive it. Ignore the output power level (I can't
believe I just said that ;-) )
A suggestion from the fldigi setup procedure work a treat. Monitor the ALC level on your 706 and
wind up the drive of your TT3. Once you see the ALC start to increase, back the drive off until
there is no ALC.
In the lead up to a Simpson crossing in 2009, we went into Bendethra; where I got packets into ZL.
There are a lot of HF Igates scattered around Oz so you should be right; your antenna and it's
placement will have a big influence.
When I go away, I have a shadow (and "rear details" to make sure my PSKMail server behaves itself).
He reckons it is like watching me around town :-)
Drop me a mail off-list if you want photos of my setup.
