Many thanks, Jim, for clarifying the fact that the RESET directions in the Baofeng manual are incorrect. My usual presumption is that the manufacturer knows best, and so I consulted the manual. But when the procedure did not work with the [FM] button as described in the manual, I had the nagging feeling that I saw some similar directions somewhere involving the [MENU] button. But I was not sure whether that was in reference to some other piece of equipment or for doing some other type of operation, and I recall having the impression that that was something I should be careful about, and, based on experience, I figured it was a good idea to be cautious and to not go pressing buttons in "button-happy" fashion without more-definite knowledge on the matter.
Anyway, I realized that I had a miklor.com-alleged
"no-issues" Windows-XP-specific driver installed on my Dell D800 laptop running Windows XP. So I tried using CHIRP on the D800 and it seemed to work fine, without any error messages.
So I installed the driver that
miklor.com suggested for Win 7 on my Dell XPS. And then CHIRP worked fine on my Dell XPS (with Win 7) as well. So the problem is resolved. Hooray!
But it appears at least few items of info need to be corrected and/or clarified on the
miklor.com web site in this connection.
One is that the lack of a yellow triangle with exclamation mark next the device indication in the device manager does not mean that a good cable driver is installed for the device, contrary to a statement in the
miklor.com directions.
Another is the
strong suggestion that the error message "
Radio did not ack programming mode" is likely to be a hardware problem (provided the plug is plugged in to the radio and the radio is turned on). A natural presumption seemed to be that, due to miklor.com hardware suggestions and due
to the erratic/haphazard then finally permanent nature of the problem, the problem was an intermittent hardware problem and not a driver issue. But it tuns out, surprisingly, especially regarding the intermittency, that that presumption is not a good one.
I'll plan to contact the miklor.com people about those items.
