I have installed APRSDroid on a smart Phone (its a spare without a
SIM card), I need to read up on it's features, whether it will do
digipeating. For use on the bike I would do without the GPS receiver
if I could, otherwise where space and wiring is less of a concern I'm
OK with a GPS receiver.

Now that your long weekend is about over I should get my order in
for the MTT4BT.

I believe you can send GPS datz from an A droid device to the MTT4BT with an Android app like "Share GPS" (there probably are better ones) which will send the GPS data over BT. You just have to configure the port properly.
Note: Although you can get GPS data over a Text or KISS port, I think using the BT for GPS will prevent the MTT4BT from connecting to an APRS client over that connection. Byon would have to confirm.

during the summer it would reside most of the time on the bike.
Summers here are short, so it would be multi-purposed at other times.
The digipeating feature would likely be used, there is a single I-Node
in town, likely its the only one in the VE8 call area, and one
digipeater at the local high school. There is little coverage, but it
handles a weather station or two, and local APRS traffic.

I was wondering if the BT would carry GPS data from the phone to the
MTT4BT.

I would ask that you start with the features you want while cycling, rather than a broad question of what is the best installation. The best installation is one that servers your wants at your station - in this case on a bicycle.
For instance:a) If you only want to send postion reports while cycling, then a simple tracker like the MT-AIO would work just fine.
Built in GPS and RF transmitter with a TT3 based tracker.
No interface with a Android phone, EXCEPT where the phone is attached to APRS-IS
and the phone's APRS client receives from the APRS-IS system.
b) MTT4BT adds many features (RX, DIGI, BT to phone), but requires an external GPS. You can add a display and keyboard (probably little value on a bicycle).
With the BT interafce to the Android phone, you add all the capability of the APRS client of the phone. Most APRS clients prefer KISS interface and add a lot of features, but again difficult while bicycle mobile. There are terminal programs available that 'should allow' you to configure the MTT4BT through BT. They are typically less convenient than a computer - but mostly usable.
When I've used my MTT4 while riding, I just stick it in a fender bag with a 1/4 wave mag mount. Sometimes inside the same bag - at the far end, but usually the mag mount is on its own bracket. A small (1.4Ah Power Sonic) gell battery for power. I typically run it at 1 to 2 watts out, and turn off DIGI functions.

Hi from Yellowknife, NT,

I'm about to purchase a MTT4BT for portable use (powered by a lithium
battery). Initally I plan to install it on my (recumbent) bicycle. For
the bike minimal hardware (less space and weight) is the goal. If a
surplus Android phone is connected by bluetooth what I can I do through
it, configuration? APRS texts? In short, what is the most practical
hardware setup for a bicycle installation?

Thanks, Ron
