MicroSD card for easy programming of channels.APRS (Automatic Packet Reporting System).C4FM Digital Voice capability, and access to internet gateways.True dual band allowing simultaneous reception and transmission.
This offered more features than the radio it replaced: I chose another Yaesu transceiver for the replacement, and went with the FTM-300DE. I’ll repair the FT-7800E in due course, as I need a dedicated radio in my shack to park on the local FM repeater channels.
#SIMULTANEOUS DUAL BAND RECEIVER RADIO 2M UPGRADE#
Due to lack of time and the small surface mount nature of these parts, I decided the easiest fix was to upgrade the radio to a newer model. Studying the circuit diagram, I found there are a few semiconductors in the transmitted audio signal path which control gain and it seems one of these might have become faulty. Even swapping the microphone didn’t help. Cleaning all of the plugs and sockets on the connecting cables would usually fix things, but sadly not this time.
Mobile radios can sometimes suffer, given the harsh conditions of mobile radios in terms of vibration and extremes of temperature. That is until a few months ago, when I started to get reports from other stations that my transmitted audio was weak intermittently… It’s lived in a few different vehicles, performed really well and been easy to operate on the go. I’ve had great service from my trusty Yaesu FT-7800E transceiver for around 15 years.
