STRYKER 955 ASYMOD?

the ASYMOD cost more than the radio. not worth it.
I totally agree. but I would still love to hear one on the air. Who's buying these things anyway? I have yet to hear any Astmod product in the two years I've been on the air. At least no one's mentioned that they were on one and guys who run 6 - 20 khz direct injected motormouth Maul Studio mic equalized equipment love talking about what they're using as they're always being asked. I haven't even discovered a YouTube video of one being video gaited.

The old versions sell cheap from time to time. A thrifty person can come up with the additional power supply voltages needed dirt cheap. Put it in a scrap 29 and tap the first IF with a cheap sdr for a very nice receiver.

A cursory search reveals it to be a copy.
Personally I would go to the original creator and support him.
Is the original motor mouth device available for less?
This isn't my thing anyway. I don't like loud people on the air :)

It is a copy. When I first went to mmm about buying one he had stopped producing them and had none to sell. When he went back into production his new single voltage board the price was cheaper than the asymod. I'd definitely get with John first.

My first modulator board was built by a friend while mmm stopped selling them for a while. The guy wasn't out to make money and just gave me the thing. I tried to pay or trade for it but he would not take anything for someone else's design.

To be honest I was amazed at what it was capable of. Me being me bought some of the asymod boards as cheap back-ups just in case. I also bought a stack of the opamps for a rainy day because you know how obsolete things can become impossible to find.

BTW. You don't have be loud of you run one of these. They just give you a wideband transmitter with a flat frequency response. How much modulation and how much bandwidth you use depends on how the board and your audio chain is adjusted.

I've been using a different transmitter the last few months but the boards work well in the right hands.
 
Cool. Thanks.

I guess my issue with this is that it does not seem very bandwidth friendly and would be prone to causing interference.
 
They're a blank slate, what you put on the air depends on what you put into the board. Just limit the bandwidth of the audio you feed it and that's the bandwidth you'll transmit.




PS: Sonar, have you tried just manually typing the address of the video you want to post into your post?
 
I've been intrigued by the whole asymod thing but I'm not completely educated as to the full benefit other than wider bandwidth. There's a guy local that runs one on a base and his station sounds great, but I've heard others that sound great too and without the asymod.

I guess I've not had the pockets deep enough to venture off into the asymod world yet.
 
ASYMOD is a contraction of two separate words, ASYmmetrical and MODulation. it doesn't make any sense that anyone would need to add anything to any am, fm or ssb transmitter to achieve "asymmetrical modulation" since the very nature of the human voice is already asymmetrical and non-sinusoidal.
