I recommend to refrain from installing it until after the PAT board is installed, and the Teflon coax has been installed onto the SMA connector. Once the chassis is prepped to accept the SMA connector. During drilling, it's handy to have a friend vacuum the loose aluminum shavings, to prevent them from accumulating inside the radio. Ensure the planned location for the connector and hardware, will clear the circuit board, and any protrusions that are inside the chassis. However, before you mark the spot to drill the hole.
I found a convenient spot on the FTDX-1200 near one of the rear corners of the chassis. Next, I recommend that the chassis is carefully drilled, and prepared to receive the rear mounted SMA connector. All connections are made on the component side of the transceiver's main board.įirst, remove both halves of the cabinet and set them aside. The last connections are the two ends of a length of Teflon coax between the PAT board and a rear mounted SMA socket. The installation is straight forward, and only requires a wire to be soldered between the PAT board to one leg of a relay, a wire soldered to a test point to provide DC power to the PAT board during receive, and a convenient ground connection to the PAT. Unlike the FTDX-9000, it is not necessary to remove any circuit boards or dissemble the radio beyond removing the cabinet. The addition of an IF out jack on the FTDX-1200 is not too difficult. I recommend the PAT board for reasons set forth in this article published in RadCom. Directly tapping the IF, offers no protection or constant signal from the IF chain in your expensive transceiver.
Several individuals on the web, have directly tapped the IF on the FTDX-1200, without using the PAT board.

The installation kit contains all the parts necessary to install the PAT board into the transceiver. I highly recommend ordering the assembled version, and also an installation kit from Dave, G4HUP. If someone is not accustomed to working with small surface mount components. The correct G4HUP PAT board to purchase for the 1200 installation is the model PAT50M ( G4HUP PAT board). Similar to a FTDX-9000 I previously modified, the FTDX-1200 does not come from Yaesu with a factory installed IF out jack.īoth the FTDX-9000 and the FTDX-1200 share the same IF frequency of 40.455 MHz. A key building block to achieve a working IF based SDR Panadapter. Recently, I've been contacted by several individuals regarding my installation of an IF out connection for a Yaesu FTDX-1200, utilizing the G4HUP PAT board.
