Rob,
The Eico 720 requires the Eico 730 Modulator for AM, and it will work better
if you also have the Eico 722 VFO. I my station I also use the Eico 717
electronic
keyer for CW work. I have the 723 transmitter and a separate 730 modulator
for it.

The manuals are available for all of the Eico ham equipment at the "Bama"
site.
I have several pictures of the other equipment at:

You will definitely need a modulator to run AM with the unit. I also advise
not to
turn it on without a jumper between pins 4 and 6 on the rear octal socket.

The rigs are good low power AM/CW station equipment, and provide for
switching
115 VAC to drive a TR-relay out of the rear socket also. LP CW is great fun.

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 the Eico 720 Transmitter are
greatly appreciated!
