Re: [RCSE] Memories of Dave Jones
I didn't know Dave THAT well either, but got a chance to talk to him a couple of times when he came over for the IMS show in Pasadena. Once (I think it was two or three years ago) we even had the honor of having him talk at a Torrey Pines Gulls club meeting during his stateside swing. In general, the entire monologue was entertaining and informative, but he brought the house down when he explained how he had to sometimes counsel US authors who wrote articles for QFI. Since TPG is a "hotbed" for hand launch glider activity and the IHLGF was but a few months away, he wanted us to all know that we had to be careful in phrasing articles. It seems that the phrase "hand toss" has a completely different connotation in the Queen's English.. He did it absolutely deadpan. There wasn't a dry eye in the house...

[RCSE] Fwd: Soccer field construction started today at Camp Maluhia
Aloha to all. To my surprise and dismay, construction has started on the soccer field at Camp Maluhia. I was talking to one of my buddies that work for Goodfellows and he said that they are going to start work on the field today. Goodfellows has already moved that irrigation line that was in the middle of the field today. Starting tomorrow, they will start filling in the area where we usually launch from and raise it about two feet. There will be semi-trucks going up and down Maluhia starting tomorrow to do this. They will be using the dirt that comes from the improvements that they will be making on Kahekili Hwy this weekend. The road to Kahakuloa will be blocked off tonight till Monday morning (from Camp Maluhia to past Kahakuloa town will be closed). As I mentioned earlier, my buddy said that there will be access to Maluhia, *but*, Goodfellows will be grading and filling the launch area for the soccer field. Is this the beginning of the end?

[RCSE] Radio Interference; (was General sailplane radio: FM or PCM?
Interference type versus signal detection type. There are two types of interference from channelling standpoint, co-channel and off-channel. Co-channel interference (1st) takes place when one or more additional Tx is operating on to a busy channel. Result is the reduction of signal quality marked by the ratio = (signal) to (noise + interference*). where (*) marks the variable. Quasi-co-channel interference (2nd) takes place when a mirror image of the wanted signal is reproduced by reflective object and find a way to the same Rx. It is called multipath fading. Same effect as above. Quasi-co-channel interference (3rd) takes place when metal to metal junction is rolling, sliding or make/break in operation or under vibration. It produce RF signal phase modulation. It share the same appearance as above. Two Tx co-channel in the extreme case produce a capture effect where the unwanted co-ch-Tx is taking over the authority of the Rx when the same Rx to Tx spacing is larger than 3~4X as far to the wanted Tx than it is to the 2nd Tx. When the Rx is equal distance to the two, none of the two Tx is in command. Some servo in a PPM system will bang from limit to limit. Off-channel interference (1st) takes place when one or more Tx is operating next to a busy channel with no specific channel relationship. Result is the reduction of signal quality marked by the ratio = (signal x B*) to (noise). where (*) marks the variable. B is the blocking factor, its effect is RF signal amplitude reduction. Off-channel interference (2nd) is like (A) but with specific channel relationship. (If desire channel is ch(c) and the off-channel are ch(a) and ch(b) such that c=2a-b; or c=2b-a' a and b are integers) The effect is taken as co-channel effect. Perceived Rx interference takes place when we are not aware of a normal servo operation may be subject to RF interference when the servo signal cable acts like an antenna and its electronics acts like a receiver under strong Tx signal at close proxmity. Servo twithcing when Tx is ON may be the symptom. Such causes may be verified by an experimental 5-cell battery, if symptom persists that proves that electronics inside servo under test has poor RF immunity, or is supporting co-channel the (3rd kind) interference. If problem goes away, maintain the 5-cell battery system. Interference priority in top down order: co-channel (1st kind) ;deadly and wide coverage off-channel Blocking ;deadly but 3meter coverage co-channel (3rd kind) ;dangerous but avoidable off-channel (2nd kind) ;dangerous when Tx are clustered co-channel (2nd kind) ;concern for low and far planes. Interference sources: co-band RC equipments co-field reflective objects on-board metal junctions servo under Tx radiation co-band non RC equipments off-band equipments. Conclusion: I can see two categories, Deadly and Not Deadly. Deadly: Any thing that is persistent and strong are those 1) stupid co-channel RC Tx and 2) those big boys paging station. No known technology in RC today can safe our planes from them. That include PCM, IPD etc... Not Deadly: Are event we can get away since those occurance are by chance (when they exist) and do not take place every stretch of air we fly through.

Re: [RCSE] PCM, IPD, Fast Radios,,,,, slow thumbs
Tossing out bad data equals to update rate reduction, the effect is time delay. As the function suggest, as long as there are enough bad pulse the update rate keep reducing, when the interference duration last long enough, the result can be interpretate as lock up. But the good thing is soon as the interference is removed there is an instant return of full update rate. Karlton, am I right about that.

One wonders how many frames go by before the microprocessor gets the information to the encoder. Has anyone detected a delay? Could we have some more technical input on this? I always got a kick out of this pulse response thing, as there is no way a human could detect an ms delay in servo response in any of our radios. You can't see it with your eye but more realistically, you can't affect the minute proportional surface changes with your thumbs (unless maybe if you have the dexterity of a card mechanic or magician). As we approach 40 our thumgs move in graduations closer to 1/8" segements than one-hundredth of inches. The originator of the 'speed' post won't take the care to insure that there is no linkage slop that would eat up the 'response' speed advantage. Lets touch on some reality, the slowest radio system made today is faster in all its functions than your thumbs. So spend as little on the radio as you can, take the money you save and use it to sign up for a card dealing or magic school where you will learn excercises and drills that will speed up your your thumb and finger precision and coordination.

Re: [RCSE] Radio reception, ideas relevant to the PCM, IPD, thing?
A gadget like that differentiate between pusle out or not from the Rx. Tx ON, then pulse ON, Tx OFF then no pulse. What that is telling us is the PPM Rx have a function not so popular to the RC fans is the "mute" function. Every noticed in the old days TV tune to an empty channel will flood the speaker with white noise? as oppose to TV today only give us a blue screen and speaker mute for empty channel? A mute function do exist in our PPM Rx either intentionally by the original designer or un intentionally coloned in by some electronic artists of another vendor. By such function the noise of an empty channel is gated off from reaching the de-multiplexer, a function that turn pulse position back to channel specific signal fan out to each servo. A properly designed muting function also posses a good threshold preset plus adequate hysteresis to prevent premature muting and spurious muting in/out oscillation under low input signal condition. In a sense, muting function can be view as the "lock up" function in a PCM system. What I am trying to get at is that a good designed muting function in PPM system should be one that when interference sharp enough, all servo channel output are cut off immediately thereby holding the original servo position and by luck glide through the interference zone. On the other hand, however, a poorly implemented muting function (or scheme) can cause the spurious in/out muting under interference or at weak signals that can lead to wild servo movement. I trust IPD can represent such muting but execute the desire through our intellegen stored in code inside the Rx. The result should be better and not worse. Karlton, am I right about that?

Just wanted to add an interesting note to the discussion on radio performance/interference etc. All the talk over modes of transmission and reception are a bit over my head, but I had an interesting experience flying with my pal Richard last night that might be of interest to those generally concerned with RC transmission/reception. We were flying Richard's Handlaunch and it started to ring exactly like a cell phone. He explained to me that it had on board an alarm designed to begin sounding whenever the TX is turned off, as an aid in finding the plane were it to come down out of sight or in tall grass or whatever. Of course this same alarm happily goes off any time that the TX is not in communication with the RX, regardless of the reason, so it basically functions as an audio glitch alarm. I found it really interesting to have. We flew the plane, trading TX between us for maybe 30 minutes, and the thing maybe went off briefly 3 or 4 times. The short glitches never caused much problem. But it was really informative to learn when and where interruptions were occasionally occuring. Everyone who flies at our local hill gets some glitching, and there are various unconfirmed theories as to where and why and which occurrences are just turbulence and not radio related etc. etc.. Having the alarm was very clarifying. I'm not sure what it is called, but its about 5g, and sold by Thermal Gromit Works, and perhaps others as well. Maybe Richard will fill us all in if he reads this. As long as you are downwind of the glider, it seems as if the sound carries pretty well, but I'm guessing it probably wouldn't be useful for indicating glitching at truly speck height.
