test equipment for rf analysis

[Mike]

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.

> Mike...good morning.....I can help you with both.....I need to know the channel code on both pieces.....this will tell us everything we need to know about the pieces then we will know the next move....I have a 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.

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.
