2.0 PDF on site
I changed the url from the 1.9 docs on Radio Shack's website to 2.0 and I got an updated 2.0 PDF:
https://www.radioshack.com/graphics/uc/rsk/Support/ProductManuals/2000106_0197_V20.pdf
Changes in 2.0:
• Pressing the ATT key during scanning while on a CONV object causes the object
to be stored to EEPROM immediately. This eliminates the possibility of the ATT
status change being lost due to a Priority check.
• Changed 154-156MHz range to accommodate Marine channels
• Added duplicate checking to conventional channels created via PGM NEW CONV
It looks to me like Radio Shack is staying a version behind the GRE models. Also note the 2.0 PDF is dated from June 2011. So they sat on this one for a while. The above changes also match the PSR-500/600 2.0 firmware changes.
Looking at the changes in the new PSR-500/600 GRE 2.1 firmware:
• Fixed Marine, VHF, and UHF search frequencies
It doesn't look like these fixes are in the 2.0 firmware just released for the Radio Shack version. Given the 2.1 fix above, I assume there are "Marine, VHF, and UHF search frequencies" issues with this "new" 2.0 version.
I suppose when/if GRE releases a version 2.2 firmware, Radio Shack may provide us the 2.1 firmware (which they may already have received from GRE).
I wish Radio Shack wouldn't sit on firmware revisions that fix bugs.
