[TowerTalk] Comtek ABC switch Box.

John.



A:  yes Jim Miller  a great guy,,, sad at his passing. When I had my 160 ACB-4 installed @ 90 ft on the 155 ft tower   I wanted to re install  it at a lower level  talked to Jim and  I made a new set of ¾ wave length RG11 cables and Jim again was going to CT to visit stopped  by and  encouraged my climb and helped lower the  wires  for re installations of the new   feedlines. RIP my friend ☹





B: the picture/link you sent  looks like   the new  bought one  ,  except there is NO fiberglass tape  at all ( wires  are black/white)  has  no top Zip tie band,  other I had did to keep the toroid’s  from stressing the solder joints,    no wire relief  clamp  and no sticker label  It  also has  clear RTV on the windings on top of just ONE  toroid to hold wire in place



My other three owned ACB     (ABC just sounded better  !)        All  my other  previous units had the total  toroidal  fully  wound with fiberglass tape   !



Thanks for the link

Do you mean ACB-4 switch?

If the relays are missing their covers it sounds like the previous owner
also had issues. It a good idea to look inside at things when purchasing, I
have been burned too on used items that looked mint on the outside. Internet
photos just show tape around the torrid (does yours look like this?):

assist, the previous Comtek owner is a silent key.

Over the years I have owned  ABC 160 ABC 80 and ABC 40 meter  4 Sq switch
box...  My 80 meter  box  took a lightning hit last summer.
I picked up a used on  one of the Ham reselling sites...
Getting ready for CQWW-CW I installed it and to my surprise... it's not
working
as it should.. Examining the unit and wringing out the truth table  the
relays
are  A-OK.
There missing there covers and  the  torrids  are wound  on them but there
is
NO  fiberglass tape and there held in place with   a bead of RTV across the
top.

Again the DXeng  site says there  wound on fiberglass tape    my old unit
has
the tape

A good deal my be not so GOOD !
