Most unsual DX-60 lashup ever...

Posted By: Bradley Stone (stonebs)

Above is a picture of my latest project.  After doing the transceiver thing, with a CE20A, mated to a SX-115, then the next transceiver project, a 10A mated to any Drake R4 series receiver, I had an idea.  Those transceiver projects have a lot of oscillators, and even the crystal oscillators can drift as they warm up, which requires re-zeroing the transmitter to the receiver from time to time.

So I thought, what if one had a very stable VFO, and generated the SSB signal on the operating frequency?  In very old days, that was done, but not with a stable VFO.  At our local Belton Hamfest last year, I found this very beautiful Collins 310B exciter, from 1948.  I think it was Collins’s first PTO for ham radio.  So I recapped it, turned it on, put a “Pot” on the screen of the 2E26 to lower the power output from 30 watts to about 2 watts, then converted the DX-60 to an AB1 amplifier, as was often done to facilitate the use of the SB-10.  And this, I use to drive the Collins 30L-1.  I’m getting about 300 watts out, and having a great time.  The Collins PTO is so stable that once warmed up, it does not move AT ALL during the course of the net.

   *** The .PDF file is downloadable below ***There are lots of mods for the Heathkit DX60 on the internet. These include audio and PTT mods. The PTT mods address an issue with the function switch and makes switching between RX and TX more flexible. The Function wafer switch on an unmodified DX60 switches the high voltage secondary of the power transformer when going from standby (receive) to transmi...  READ MORE

   ** The .PDF file is downloadable below ***One of the biggest short comings of the DX-60 is the function switch, and the need to switch the phone operation to Push-To-Talk (PTT), which should enhance the operation and save the function switch.
