[chirp_users] SainSonic AP510

[Kurt]

Yup,  I flashed it to the 10/2014 firmware and Chirp reads it fine.  Sooooooo, AP510 users, you flash to the 12152014 firmware and 
Chirp can no longer work with the device.  Will have to use the programming software provided with the firmware.  Nice thing
is the device can be flashed back and forth very easily so  one may play around with it and see what they like.

I picked up a second unit and it apparently had an ancient bit of firmware on it.   I didn't get the date but
Chirp would read a frequency off of it. I flashed to the 12152014 firmware and Chirp isn't able to read it.
So, it's a firmware issue.  Also the transmit delay can't be changed but that's a Sainsonic issue and not
Chirp.  I may try flashing to an older firmware.

Go to "Downloads" and click on "AP510 APRS Software"  . 
Rename to *.zip and unpack.  I virus scanned and it's O.K.                        KC9LDH

As mentioned in a private email, Kurt actually has firmware version
20141215. Thanks for tipping me off--this is a new version I haven't
tested, and it was not released through the same channels as previous
versions.

I flashed my AP510 with the new firmware and it woke up in a boot
loop. I was eventually able to get it to connect to the stock
programming software and load the default configuration. This tamed
it. This is a good indication that some significant internal
 changes
took place between versions.

I snooped the serial protocol a bit and found they modified the
command to put it into configuration mode. This is why Chirp is unable
to read your AP510. I have not looked much farther than this, however
I suspect they did not change the initialization on a whim, but to
prevent accidental programming with software intended for older
versions.

I will need to take a thorough look at the new protocol before
updating Chirp. Hopefully I can support both the new and old protocols
concurrently, unlike the stock software.
