Plectron transistor radios were manufactured for wide-band radio systems that were in use prior to 2013. However, because of the design of the radios, they continue to function well on narrow-band systems. All of my refurbished radios (VHF/UHF) and any (VHF/UHF) radio that is in the shop for any reason will get the narrow-band audio modification as a part of the engineering updates (no charge).
I can also install a full narrow-band receiver kit which includes narrow-band filters for those who are experiencing adjacent channel interference. The cost is $40.00 which includes the filter kit, installation, and receiver alignment. After installation the radio is then a full narrow-band receiver.
Feel free to contact me if you have any questions about using your Plectrons on a narrow-band radio channel.
