-====== Yaesu FT-450D ======
+Relocated to [[radios:ft-450d|radios:ft-450d]]
-m to 6m with ATU capable of matching 3:1, 100W. RS232 CAT control. 6 pin mini DIN data port. Easily modified for RF or IF output to an SDR using a HupRF board.
-===== Usage with NinoTNC =====
-The Yaesu FT-450D works well with the NinoTNC but requires some audio isolation between the TNC and the radio in some circumstances. This can manifest as wideband noise on transmit. Discussion was had [[https://discord.com/channels/715554730323083274/1204840691142889562|here]].
-Full isolation (including PTT) does not appear to be required - simply cut the ground and TX audio lines in your radio-TNC cable and insert an audio transformer between them. Ensure there is a ground path for the PTT line - in my case, using a Pi with a 12V-5V DC-DC converter, it was sufficient to ensure that the negative side of the input and the output of the DC-DC converter were common.

-Previously there was an article here involving a full isolation circuit with relay powered by DC brought out from the TNC, but this has proven to not be necessary.
