I've got two scanners, but
they're both blocked from 512-806MHZ. I didn't pick anything
up from 170-174MHZ from the mic, but didn't really expect to
since it is marked UHF.
I've got a handheld
transceiver, but it is only 144-148MHZ, so I cant test any
transmission ranges to the receiver.
Thanks for your
help so far, any else I could try?

Sorry for the delayed
response... I'm not sure what you or Anchor mean
conflicting, I thought I posted in the original
message these are 'incompatible'. I want to
know _how_ they are incompatible- eg what did Anchor
change, and can anything be done (by me) to make 'em
work. I own both and therefore can mod
both. I observe the mic appears to have a jtag
interface. I suspect the single rx/tx channel
combo where I can receive, it is simply hitting a
harmonic.
Thanks for the info about
the freqs, the receiver is s/n
H30000506. The mic is either s/n 0217376374 or
s/n C3003792.
I'll try to play with the mic
with my scanner and see what I can see, I don't know
why I didn't think of
that...

Mike more info on the
Anchor unit....you list conflicting models and wh
numbers....I know a tech in Anchor Audio and
called him......The eairlier series used Vhf
170MHZ freqs and the later units used 700 MHZ for
a very short time then they switched to 682 to 698
MHZ freqs. Sense our HAM radios or a scanner can
get to these freqs. you can scan them for the most
part. Triple check the model and also the serial
number is the key to nailing down what you
have.....next step is yours....Phil

[LakelandARC] Re: test equipment for rf

Thanks for responding Phil, here's the
info I have on the Anchor equipment;
The
receiver is integrated into a loudspeaker
MegaVox Pro model MEGA-6000U1. It is set to
wireless channel 9.
The transmitter is a
hand-held wireless microphone model WH-3000.
With the mic set to channel 4, with the
equipment in close physical range (~5-10 feet)I
can get the rx link lights to illuminate on the
receiver and it will demodulate audio as
expected. It doesn't lock onto the signal too
well and will lose the lock often depending on
mic orientation.
I cannot find any
meaningful documentation on the mfgrs site, but
a call to their support revealed these are not
intended to be compatible. I don't know if the
incompatibility is with the channel 'codes',
modulation technique, or carrier.
I
don't have physical access to the drive-in
equipment, but swear to myself every time I
visit the drive-in that I will bring up the
topic here, and finally I'm getting around to
it. If your equipment is at all portable, I'd
just like to give the signal a look-see to see
if anything jumps out as being mis-aligned. I've
simply never had a good experience trying to
tune their signal from various locations on the
property using a variety of FM receivers. I
figure if I have problems, everyone else
probably does too.

optoelectronics near field receiver that is used
on my bench. The lakeland drive in transmitter
that you want to see is probably a Ramsy
product. I install these and set them up also.
What is the model number and I can tell you your
next move on that also. Phil K4BHE

16 channel UHF mic from Anchor anchoraudio.com -
and a 16 channel uhf receiver from the same
company that are incompatible according to the
mfg. I suspect the carrier freq is shifted and
that's why they're 'incompatible'. There is a
single channel where they kinda work, but not
too good.

All I've got is a 60mhz DSO. I'm looking for a
spectrum analyzer or whatever you've got and
some RF know-how. Anybody wanna try to help
figure this out?

I'd really also like to look at the FM signal
for the lakeland drive-in. I suspect simple over
modulation, but would really like to look at the
signal.
