EICO 720 Transmitter.......Anyone ever use one of these??????

[WF2U]

Hi Rob,

Good Boatanchor haul!

As to the Eico 720 transmitter: You definitely "need something in between
the Mic  and the Transmitter... " ! This something is the Eico 730
Modulator, which is much scarcer than the transmitter itself!  Otherwise
you'll have to either build a modulator or find a PA amplifier of the
appropriate output power rating and a matching transformer from the output
to the required modulator impedance into the RF PA tube.

Good luck,

Hi Guys:

   Yesterday I was fortunate enough to pick up a few more Boatanchors for
the collection.....Another RACAL RA-17 with ISB Converter, and an EICO 720
Transmitter. The Transmitter is in Nice Condition both Physically and
Electrically...a Real Cool Looking little Rig!!
I do not have the Manual for this yet.....so don't know much about
it...except that it's supposed to be 90 Watts CW and AM????
Has anyone out there got one of these...or have you ever used one??? I
would appreciate any comments on the Rig either Good Bad or Ugly!!

Is it possible to hook a Microphone directly to the Rig??? I see there is a
Plug on the Back of the Transmitter that says "Modulator"......Do I need
something in between the Mic  and the Transmitter...or can a Mic just be
wired to that plug and away we go???

Any info, advice, comments pertaining the Eico 720 Transmitter are
greatly appreciated!
