Hello everyone,

I am trying to restore  HAL ST-6, but it’s not exactly like to pdf manual I have.

The motor connector at the back is a 8 pin tube socket, and the fuse holder at the front has been removed and replace with an inline fuse holder behind the front panel.  The panel hole now has a toggle switch (on-off-on) and it looks like a 3PDT.

When I turn the unit on the receive light is always on. The space light is on, even with no signal if the “new” toggle switch is in the middle or up position.  If I flip this switch down then the space light goes off and the mark light goes on.

The meter will peak to 0.6 on a 2125 (actually 2140) signal and will peak to 0.62 on a 2295  (actually 2320) signal.

The filters need adjustment, but at least they are 180 apart.

The wiring inside the switch looks original.

There is an additional board in the extra option slot.

I don’t know what this is doing.

In addition, when I am in standby and I peak a signal I don’t hear the relay activating.

Sound like multiple problems.

Any suggestions please.

Thanks, Fred Weksberg VE3WN / VE3PIE
