RF receivers..

[Rogue]

Help.
Anyone know where i can get a hold of a handful of 446Mhz or 462Mhz RF
receivers.
Don't need to be able to receive voice. Just act as a switch really,
it's for a pet project i'm working on.
Any help on this would be muchly appreciated.

Regards
Peter P.

The inexpensive superregenerative ASK (i.e. AM) RF receiver modules ($5 from
Mouser) listed here...

http://davehouston.net/modules.htm

are tunable over a wide enough range that I suspect you could tune the
433.92MHz versions to the frequencies you need. Note that I haven't actually
tried this but have tuned others by ~50 MHz.

Using the soundcard setup shown here...

http://davehouston.net/learn.htm

you can rough tune by ear. The linear output on pin 3 can then be used for
final tuning.

If you need FSK (i.e. FM) these will not work. FSK pretty much requires
receivers designed for these frequencies or programmable modules that get
much more costly.

I'm curious - what pets transmit at these frequencies? ;-)

Don't you think it would be more fair to the OP if you at least tried it to see if your product works?

How many of the products that you sell or recommend have you actually tried?

I guess it's hard for bass to read with those beady little fish-eyes. The
page I referenced merely lists several vendors around the world where the RF
receiver and transmitter modules can be purchased. I do not sell them.

I have never sold anything online despite the frequent lies and
misrepresentations by Bass and his mud-wrestling tag team partner claiming
otherwise.

Having no need to tune a receiver to the frequencies listed by the OP (and
not having any pets that transmit at those frequencies) I have not tried
tuning one and, despite my helpful nature, I have no plans to buy the
transmitters in order to test whether the receiver can be tuned to match.

I was merely trying to point the OP to a possible $5 solution.

I guess it's hard for Mr. Houston to carry on a discussion without resorting to grade-school insults.

You sent readers to your website. Perhaps if you'd sent themn directly to the sellers' websites it would have been clearer.

Yes, we know. You tried to market a few things but failed. There was a CHA thread a couple of years ago with a detailed history of
your mistakes, missteps and miscreant behavior.

And how long before he trots out the failing health excuse, again...

You're no lilly-white virgin either so how about sticking to thread topics,
the lot of you!

I don't know. It was in response to his plea for assistance due to "failing health" that I sent a private email offering
assistance. I honestly tried to make peace with the guy. His response? He attacked me in the newsgroup claiming that I was trying
to steal his useless ideas. Needless to say, I have little patience with him and less sympathy than that at this point.

> You're no lilly-white virgin either...

Considering I have two grown sons I should say not. :^)
