Today I was in attendance at the National Hamfest, and Yaesu have answered my question, they informed me the new TX/RX ID function is similar to CTCSS, works with networked (not Internet linked but radio linked) repeaters and is called System Fusion II, something I had seen advertised, I had also seen the new System Fusion II repeater, I also looked at the new online exams being rolled out and a look at the equipment used for ATV courtesy of BATC.
I picked up the Advanced book from the RSGB book stand and had a look at a smart phone DMR and various other bits and pieces useful to Amateur radio operators, unfortunately I wasn't able to get the handsfree mic for the car as this was unavailable, and other items such as a base antenna due to financial constraints.
Needless to say, the car chose the journey to develop another fault, initially detected as a developing oxygen sensor malfunction (on the sensor post-cat), however when I had chance to look under the car at the exhaust this revealed a massive leak in the exhaust system as the centre pipe (which includes the post-cat O2 sensor) had parted company with the catalytic converter, so my car sounds very much like an old motorcycle or tractor, and I will keep the car off the road until I can fix it unless I have to use it, ruling out October's 2-metre FMAC.
Otherwise I have had a good time at this year's National Hamfest and hope to do it all again next year.
