    Yaesu FTX-1 MARS Modification

    I know this is an old post but I just seen that GMRS can be enabled by replacing a chip when doing the MARS Mod. This was said to be available by Gigaparts and won’t void the warranty? Anyone know the chip?

    RCI 2995DX power issue

    On another note it has the R2 adjustment for the “fire starter” and was wondering if that is what’s set wrong causing the issue with the amp board?

    RCI 2995DX power issue

    Well I found the issue it was the voltage regulator, tested good with cheap Chinese tester but when bench tested with power supply no good.

    RCI 2995DX power issue

    Unfortune Unfortunately it’s the 4 R5 transistor's that I believe may be IRF520’s also? It was putting out 7 watts dead key and 23 watts modulated with the amp keying 2 wires disconnected. Something went wrong?

    RCI 2995DX power issue

    OK to make sure it wasn’t in the amplifier I totally removed and connected one of the coaxes from bottom side to main board. I just wanted to make sure the amp wasn’t in the chain at all. Still same results as I assumed but it does make it easier to move around now.
