I replaced the old EPROM (JDVF from 1992) with the latest JQGA from 1996 a few weeks ago.
The radio have behaved OK and I have not found any issues with this software version.
Audio improvement on higher bands.
Bought the EPROM on ebay from Gordon in California US. Exelent service and EPROM was in my hand only 5 days after purchace on ebay.
