I recently purchased a second-hand Tokyo 144 MHz 35 watt FM mode amplifier through a VK3 private sale. The amplifier will make a nice addition to compliment my QRP SOTA rig Yaesu FT-817 on 2m. Input to the amplifier will be via a short length of coax from the FT-817 front BNC socket.
Tested the amplifier with a low power carrier input on FM and CW. The amplifier operates as expected, all switches and relays have an audible presence.
If anyone reading this post has a manual/circuit diagram for the HL-35V amplifier I’m looking for a copy 😉 Tokyo dropped its internet presence sometime ago, meaning User Manuals are not freely available online. 😧👎
15 June 2016 update. Special thanks to John in Port Macquarie for a copy of the Digitor D-2510 user manual and circuit diagram, which is known by some to be the same as the HL-35V. 😉
