Duane Mayberry ZS6DJM has posted an amateur radio video on YouTube showing his Spectrum Communications 70MHz transverter built in to the battery compartment of his Yaesu FT-897. I'm sure if he was making these commercially he would be killed in the initial rush. The last time I saw anything this neat it was a home built transverter in the battery compartment of a Yaesu FT-290. This design looks somewhat more accessible due to the use of a kit for the mod. It is a pity there are no more details of what was done to get it to fit. Thanks to Tim G4VXE for putting the video on his blog and to Dave G4AQK for tipping off Tim about it.
