Re: HX-40 & SX-140

 


3.885 and 7.290 are two good ones.
7.290 runs a "Lunchtime Forum Net" at about 1pm EDST
hosted by KC8ZUL.? 3.885 is pretty busy in the evenings,
depending where you are.

I had an HT-40(K), and it was pretty decent for Control
Carrier Mudulation -- Just don't drive it too hard.? With
a decent antenna, you'll do fine.? (Have a spare 6DQ5
around.? it's a "sweep tube," and doesn't like a lot of
continuous key-down poweer like AM.)

Subject: [HallicraftersRadios] HX-40 & SX-140

Hello everyone,

I am trying to get my HT-40 & SX-140 on the air.

I do have the T/R relay working.
This is just a coax relay switching between the? TX & RX antenna ports.
My SX-140 has had a so-239 installed to use instead of the antenna screws.

I have output with a crystal.

I can't get the HA-5? to work with it.
I am confused with the pictures in the manuals as how to hook up the key
line from the HA-5.
I see there is +12vdc on the key line and I am not sure how to make this
all work.

My goal is to use this mostly on AM.
I need to find out where some of the AM operation is and see if any of
the crystals I have may be close.

Thanks much for any help,

Dave KC3AM
