Another newbie DX60 Question

(1/1)

N9NEO:
I have to put ptt into a friend's DX60.  I did Bob's -K4TAX  audio mods and have gotten very nice reports using D104.

From what I can tell from schematic of function switch, I need to key B+   So looks to me like I can just put NO relay contact in series with B+.  DX60 just stays in AM position and relay does it all.  He is using outboard HG-10B vfo as well which runs off of 300v B+.

I also have to key TR relay and some kind of receiver mute.  And he also needs a contact close for his Keenwood leanyar.  

What's the game plan for this sorta thing?  One big relay with lots of poles or relay a drives relay b and so forth?

And I don't understand why vfo is keyed on these old boatanchors.  Won't it drift for a few seconds after ptt while it warms up?

Hi N9NEO,
  The DX-60 is one of the most "easy" transmitters to incorporate
  PTT.
  You do not even need to "dig into" the xmtr as I have done PTT
  on mine using an "external" relay box with a couple 12vdc relays
  which are "activated" by my D-104 microphone.
  the relays simply switch the ant from rcvr to xmtr, and I also
  have a set of contacts "in series" with the normally closed key
  jack on the front of the transmitter which just "keys" or "unkeys"
  the xmtr.--You dont even need to get into the rig to mess with
  the B+, and this "scheme" works great.
  If you want, --I will mail you a small print , if ur address is ok
  on QRZ.com.
                                     73`s, Rene, K1MVP :-P    
   
   P.S., depending on how many "functions" u want,--such as rcvr
           muting, etc, etc, u just can add an additional 12vdc relay
           in the "external" PTT relay box es away u go.

Rene,

Ok, that would be good. I might have a question or two about install.  I know DX60 is easy rig, but been away from radio long time.
