[Dx4win] Icom 7800 VFO readings not working with DX4Win 7.0702

[Larry Gauthier (K8UT)]

A new user of DX4Win, W8TE, is trying to get his new CI-V cable [the popular 
one from eBay] working properly with the latest rev of DX4Win. His 7800 is 
firmware rev v210, and he's running the CI-V setting at 4800 baud with the 
transceive setting = "off". He has the Contest Mode set for "$$" so his 
Notes field should contain the 7800 frequency - when it works properly. 
About 30% of his QSOs record the right freq, but the other 70% show the 
frequency as "471,417". If he opens DX4Win's ">Radio > Set Frequency" 
window, he can see it jumping between accurately reading the VFO and this 
weird "471,417" number. (He upgraded from DX4Win 7.05 to 7.06 to 7.07... all 
of which showed similar results). Other features of the CI-V interface, like 
jumping to a double-clicked packet spot with the correct frequency and mode, 
are working correctly.

His contesting software, N1MM, always reads the VFO correctly.

Is there anyone out there with a v210 7800 who can shed some light on this 
for us?
