Noticed your Baofeng DM-5R warning, hopefully some other buyers took note.
Several friends here in Toronto were going to buy one on eBay and asked me to research the radio for them beforehand and right away I noticed it did not support Tier II operation. Contacted Baofeng Support and got a slightly blank answer. Moral of the story is to research the Radio (or any) thoroughly before you purchase one. More than likely this DM-5R Model is a radio meant for local Commercial communications only and not really Ham use, until they upgrade the whole radio.
Anyways, one friend purchased the Connect Systems CS-580 Model instead which comes with their own Connect Systems enhanced software. He is going to loan it to me later for testing purposes and I will put together a review for one and all. By the way it is really a BFDX-503 Model in disguise, even the BFDX name shows on its photo on the CS website. Well built too. Not too sure about the 30 minutes under water test though...
Amazon.ca has imported a few Zastone D900 DMR HTs quite reasonable here and a few firends bought them, still awaiting reviews from them. Great radio and specs, although no GPS feature. Not a bad entry-level radio to consider, the programming software is reasonable to figure out.
Personally, I will buy the Radioddity GD-55 with GPS which seems to be the best radio other than a high-end Motorola (Radio of Gods).
