Again, I have found that one can recover from lockups and generally flaky
behavior in D700s by using the "VFO Reset" function. In the menu system,
select "Radio, Aux, Reset, VFO Reset" . You DON'T lose anything stored in
frequency memories or in PM memories, but it does re-initialize the
processor. Just do the VFO reset and then load a PM to restore normal
operation in just seconds. I've done it many many times to recover from
laptop-crash-induced or USB<-->serial-dongle-induced lockups on the Interstate
at 70 MPH!
Another 700 bug (is there any end to them????) I have observed that creates
hyper-jumps is switching to standalone "APRS" operation after several hours
(and hundreds of miles) of operation in "PACKET" mode with a computer.
(Running with UIview mobile, the radio's internal beaconing is disabled; posits
are formatted and set to the radio by UIview itself.)
Apparently the D700 caches the last GPS value transmitted during standalone
operation. When you exit the computer/Packet mode, the first beacon in APRS
mode will the location where APRS mode was previously stopped; i.e. hundreds of
miles behind you! Cycling the radio off and then back on (or reloading a
PM) clears this, but it will create a hyper-jump on findu. On the other hand,
APRS.fi, with it's rejection of outlandish posits, is unaffected by this bug.
