anyone interested in running CQUAM? have a Delta ASE-2 Stereo Gen Available

here is a link to the manufacturers website for the ASE2 it is still in production and supported.

Why would you need a stereo exciter for a Rangemaster?

was something i was toying with. interfacing a cquam exciter to a rangemaster. you are still limited to 100mW and 3 meter antenna even when running am stereo so i wanted to run the cquam into a rangemaster and keith had told me how to do it.

i have two be ax10 exciters (these are PLL) and dont need the delta ase2 (which is crystal)

I have a Sony SRF-A100 AM stereo receiver,
which many consider to be the best AM
stereo receiver ever made from that era.
(The early 1980s.) I understand that Sony
still makes a similar AM stereo portable of some
kind, but you have to order it directly
from Japan.

My SRF-A100 works fine, but is in very poor cosmetic
condition. It has no front panel. I plan to
try to fix it up, but that's on the back
burner. I would never part with the radio,
even though it's appearance is so poor.

I do not have the money to invest to
transmit that old AM stereo system, but
I can dream, can't I?

By the way, if you go to YouTube. and type
in "AM Stereo" you will find some recordings
of some stations that used this mode in the
past. The quality varies from pretty bad to good.
I was amazed when I listened to an old recording
of WOWO in Fort Wayne, Indiana. The person
who made the recording was almost 500 miles
away and it sounded pretty good.

Another recording that sounded good was from
a station in Tokyo, Japan on 1242 KHz (?)
They were playing hits from the U.S., but
talking in Japanese.

It was a great time back then to listen to AM
radio in stereo. It sounded pretty good, but
now it's mostly gone. I believe there are two
stations here in Connecticut that may still be
using that system. This is probably because
nobody changed the old transmitters and
the associated wiring. I know of one station
that is still playing music. I'll have to check
it tomorrow. I can only hear it during the day.
Maybe they are still transmitting stereo with
this old system.

Well duh..obviously pro gear is built for pro results. But do not readily dismiss the performance of the C-Cuff or ASMAX. Both of those are excellent alternatives for Part 15 and considerably less expensive for Part 15 use.

I find it quite ironic one would spend thousands of dollars on front end gear only to end up being limited by a mere 100mW limit on the tail end.

Might sound impressive....but really considering the limitations on 15.219 installations...as one member asked....is it really worth it?

Nope.

Perhaps one day someone with a fat front end will be able to get a license and put that expensive pro gear to real use.

What was that saying..."too much box for the job". I think this fits nicely with using professional exciters etc for Part 15. Lets hope the field inspectors who come to inspect your rangemaster modified with this pro exciter driving it consider your certified rangemaster as altered and outside of the certification. 😛

All C-QUAMers will love this quote

I’ve always said – if you want to see surprising new life in the AM band, s**t-can the stupid irrelevant NRSC pre-emphasis filter and allow stations to run to 15 kHz during daylight hours and 10 kHz nighttime. Mandate C-QUAM in all receiver and receiver devices.

It will sound better than HD, be more robust, and cause far fewer problems. Plus it wouldn’t obsolete a single radio out there, while making a whole bunch of them sound a whole bunch better.
