The Astra series probably has the same system but was easily overlooked unless you were a Murphy dealer and knew all the Murphy tricks. John.

Hello John,
Yes, the Astra series used the same VHF radio tuning set up - there were three little “switches” involved.
I certainly agree that the MAZDA CRTs fitted didn't last long, unfortunately.
I sometimes wonder - if Murphy Radio had continued as an independent company - what the next chassis after the Astra (presumably a fully dual standard one) would have been like.
