Jack,

I understand the limitations of operating motorbike mobile! I operated 
bike mobile for several years in the late 1980s. While I only was ever 
equipped for VHF and UHF mobile, I understand the problems with space, 
physical robustness, interference suppression and power budget. Back 
then, equipping a helmet for sound was something of a challenge as well. 
I used a dual-band hand-held (Yaesu FT-727R) strapped to the tank, a 
separate SLA battery, and a homebrew pack-rack mounted 1/2 wave end-fed 
vertical antenna. I'd love to follow you into HF mobiling, but need 
forst to get my bike back on the road (1985 Honda FT-400).

You might be interested in trying PSK31 and MFSK16 on your PDA -

This interesting new software operates both PSK31 and MFSK16, and I have 
no doubt that more modes will follow when OK1IAK works out how to do it. 
The software is based on a porting of gMFSK from LINUX, and so there is 
plenty of opportunity for new modes to be added.

While there is other radio software for PDAs, such as a packet program, 
I don't know of any other HF digital mode software.

I'm envious of your bike!

73,
