I finally got my project done involving the interface of the "Mr Pecker Pulser" to the Yaesu FT-450D HF Transceiver.
The Yaesu uses the RJ-45 Modular Connector, so I interfaced to the rear of the FT-450D. This connector requires a 6 Pin Mini Din male plug.

To use the pulser, you must select Radio Menu  "D Type" to User-L or User-U
"Packet Mode"
The Mode Switch must be changed to "DATA" mode to use the Pulser. After tuning your Amplifier,  change Mode back to USB or LSB etc. The 5 K pot is for adjustment of the Pulser audio level to the FT-450D.







I find that using the Mr Pecker Pulser saved a lot of wear and tear on the amplifier tubes. I use them on all my amplifiers.
