Title: Heathkit Daystom HA-10 Liner amplifier Relay mod
Post by: CE 3 LQH on June 04, 2005, 11:11:26 AM
Ok the HA-10 linear I have aquired has the tranciever relay mod in it.  I am trying to use it with an HW-101 which is actually the rig that was supposidly used with the amplifier.  I tried hooking it up but no luck in energizing the relays.  here are the contact wireing to the best of my observations:

Contacts 1,2,3, and 4 are shorted together
Contacts 5,6 are both connected to RF output from tubes (Biggest coax)
Contacts 7, and 8 are connected together to go to RF input of the Tubes
Contacts 9 and 10 go to RF output PL-258
Contacts 11 and 12 are Rf input form transceiver
Contact 13 looks grounded through some diodes and capacitors but not sure
Contact 14 is sent to other sides of diodes and capacitors of contact 13


It doesnt seem to be the same as the mods I found online so I would like to know if this was modded right or something!

You can get the users manual at my yahoo site i put up for the hard to find manuals for the rigs i have that I somehow found!
