Tried changing some things to try and get Alinco programming software to break.
Prolific serial driver 126.96.36.199 works best. This is confirmed on the web on quite a few sites, for other cables and sofrware.
An earlier (V2.0 from 2005) also worked.
Driver V3.3 appeared to be OK in Device Manager but gave a Port Error.
Driver V3.4 installed but Device Manager said it could not start.
I had 3 different versions of the programming software installed, but only 2 worked. Both of these were from 2010, the oldest (2009) version gave an error message when trying to read (not Port Error), this could have been a mismatch of firmware or different regional model.

After over 4 years, I've still not quite figured out the PC programming of my Alinco DJ-G7 handheld.
Usually the software refuses to do anything except display a "port error" message. But I'm not sure whether this is a 100% hardware fault as the error message is different when the radio is switched off.
At the moment I've got it working well enough to do a complete read. Here are some things I've worked out:
The baud rate of the COM port does NOT need changing to 57600.
My cable has 2.8V on the ring of the 2.5mm jack plug (it's not an original Alinco cable).
The cable can be connected before the radio is turned on.
Then the radio can be turned on before starting the software.
My programming software is V1.3.3 (the splash screen says 1.4).
I'm using the 32-bit version of Windows 8.
USB to serial driver is Prolific V188.8.131.52 (date 31/07/2007). Windows 8 tries to install a newer driver.
If the software says it is no longer responding when reading all memories (after about 23%), leave it to carry on, it takes a long time but will complete (after a Port Error!).
I'm not sure whether it works at all with 64-bit versions of Windows, I tried recently with Windows 8 64-bit and I couldn't get it to work at all.
Now to try and break it.

FT-817 doing WSPR, using a very basic audio cable (3.5mm jack plug cable and Cat 5 cables cut up and twisted together with a 100K resistor in the middle). The receive audio comes out of the 6-pin Mini DIN connector.

Moved the end of my wire antenna today and shortened it a bit, still resonant at 8MHz. Untied it from old washing line post and moved to a fence post as the old post has metal bar in it (old post in photo).
Expected a bigger shift in frequency, maybe something else nearby affecting it.
Might be about 2db better on 20m locally now.
