A number of subchannels are defined across a wide band, and then the specific subchannel used for any short sequence of data bits to be sent is selected, if I remember correctly, by ORing a Walsh code sequence with a pseudorandom noise sequence. The transmitter and receiver "know" what the Walsh code bit should be, and also know the seed for the pseudorandom bit sequence. Therefore, the receiver "knows" in which subchannel your data bits should appear. The next subset of data bits will appear in a different subchannel based on the Walsh code and pseudorandom bits expected at that time. If you are some other receiver, and you do not know my Walsh and pseudorandom code seed, you do not know in which subchannels to look (kinda like 'whack a mole'). so all you receive is noise (probably white noise, but I'm not sure about the statistics) Anyway, that's how I remember it - might be wrong in some particulars, but that's the basic story. Hence, the selected subcarrier DOES hop across the wide band used for your (and everybody else's) messages. But my bits are mine, yours are yours, (and there's security and no interference). It's just that Hedy used a player piano roll to select the subcarrier rather than a pseudorandom sequence.

Lamarr's approach was certainly brilliant, Antheil's implementation a little less so; in any case the USN dismissed it as impractical. That's not a bad idea given how hard it was for RCA and the Army Air Force and USN to develop TV-guided missiles, and how hard it would be for a submarine to know where to guide a torpedo in real time when it's trying to avoid detection.

My versions have several connectors and switches on the rear cover, along with matching transformers and choke internally so that they can be used on any radio that requires an external speaker. My R-390 drives the E3 spkr; the F4 is driven by the AR-88.? As for this Bluetooth model, I suspect that they just gutted it and installed an OTC Bluetooth spkr.

During research for my dissertation I found that the earliest reference to "high fidelity" was in 1930. At the time it was an aspiration, not an accomplishment. RCA began promoting "high fidelity" sound for consumers in 1938, I think, though members can correct me, after Harry Olson and the Camden acoustics lab made some significant improvements on RCA Victor's high-end consumer amplifiers and speakers. Of course that wasn't as good as the high fidelity sound systems assembled by audiophiles starting in 1947, and one could easily argue that the aspiration of "high fidelity" continues apace today.

I grafted-in a hockey puck Bluetooth speaker bought on line for $9 shipping included. It was creepy to see this rusted horn playing away with no apparent connection to anything. Of course it sounded too good. With way too much bass. The solution is to tailor the audio in your MP3 files. Then it can sound as good as a perfectly adjusted Model M horn. I say M horn because I've never had one of the pot metal AK horns where you could still adjust the driver even if you are lucky enough to have one of the few that still have good coils. Putting the Bluetooth receiver under the sheet metal base of course radically cuts the reception pattern. For grins and giggles I have done most of the work on making a mold that will allow casting of a urethane resin base that is pretty RF transparent. Maybe that will get done before the spring but I have some radio projects with much higher priority to clear first.

This is probably the single, most important, improvement in the TWT. ?It reduced size, reduced mass and greatly improved efficiency, all in one fell swoop. IIRC, a 10 watt TWT of the early 1950's vintage needed about 40 pounds of copper and iron to produce the magnetic field needed to keep the electron beam focused and prevent it from hitting the helix inside the TWT envelope. ?Not to mention the additional power supply also needed to power that solenoid.Jim From: Alex Magoun To: njarc at mailman.qth.net Sent: Tuesday, November 24, 2015 10:50 AM Subject: [NJARC] Vacuum tube of the future is just around the corner >From IEEE Spectrum, a nice article on traveling wave tube (aka "twit") innovations:?http://bit.ly/1IdUP3m.
