Hello all, I am having a problem that has me stumped. I am trying to upgrade a working system. Now: 2 Rangelan IIs talking over 8.1 miles line of sight plus...
... Not quite sure what could be wrong. Could be another network confusing the cards? Interference of some kind?...

According to what you tell as its seem to me that one card can not raech another one. Reason why is like that can be : Loss on one side is biger then other,...
I have a new RF sense circuit for controlling transmit/receive states on a remotely mounted amplifier. It's based around the AD8314 Analog Devices logarithmic...

Mpx, You have been busy again. I am working on an FM video TX for 915MHz and need to build a stripline coupler for the synth to sniff the RF. Previous...
... I both experimented and guessed. The coupling ratio for my application is really not critical, the coupling stripline is approx. 1/8th wavelength long and...
Intentionally jamming is a violation of FCC regs. As long as you don't care about the FCC confiscating your equipment and carting you off to jail, effective...
... For some quick ideas try 2.4 GHz cordless phones or wireless cameras / VCR extenders. Radio Shack has these for around $100. For the ultimate jammer try...

Hi! I am designing a wireless network to cover part of the city I live in: Helsinki, Finland. I find your 1-watt amplifier circuit very interesting and have...

... No, the amplifier needs the RF signal from the wireless LAN card to switch between transmit and receive. The 1 watt amplifier is overkill in most cases....

... You shouldn't need seperate antennas for transmit and receive if that is what you are getting at, unless maybe you are referring to an access point. A...
Apologies for sending a virus - it seems that InnocuLAN isn't good at
detecting them. So much for latest signatures. It auto opens, so turn off
the preview....
not that I recommend it, microwave magnetrons transmit in the same frequency range as 802.11b, don't cook yourself...

I'd been meaning to mention that. An older, worn magnetron would be of reasonably low (~3-400W) output. with a little bit of waveguide, and perhaps a...
... I heard about some people awhile ago that put an old microwave oven with a long extension cord and a hacked directional antenna on a little pull wagon and...
... Ahh.. you want a repeater. This should be possible as you describe. Be sure to isolate the antennas though otherwise the transmit side will blank out the...
New to the list and have a few questions. I have a 8 mile link that is bordering on being unstable. 90% of the time the link has about 7-9dB margin, but...

Sorry to be a sourpuss about this subject but I find the idea of an exposed source of more than a couple of watts of 2.4GHz rather scary. As a little...
... This is false, water molecules resonate at much higher frequencies, 60 GHz+ Microwave ovens use 2.45 GHz because the FCC had allocated that band for Part...
