Re: [RCSE] Re: TX RF output?]
What a novel and smart suggestion. Makes one wonder how many TX's out there have never experienced a tune-up... They don't have any moving parts. Older radios may have parts like descrete coils (sometimes with slugs) that can can change their size slightly over time (mechanical, maybe due to just moving the radio around) so its possible that the output spectrum could get misshapen (i.e. splash over to adjacent channels). Its even possible for crystals to age or get damaged. But in general what you buy should be what you'll use until the mechanical parts wear out. That's not to say that it wouldn't help to look at the output spectrum from time to time, but (IMO) suggesting to people that radios somehow require regular servicing like a car is an application of FUD. Martin Usher (time for the flameproof suit) PS. Receivers don't emit R/F -- actually they could but they shouldn't -- but if the transmitter is prone to drifting around then the receiver would be as well, they've got the same kinds of internals as the Tx.

[RCSE] Transmitter Stability
Martin raises a good point. I have to confess that I've recommended folks have their transmitters checked out every few years. But, that's based on general knowledge that I can't backup for this specific application. I don't have any hard data on the behavior of solid state equipment over time. Does anyone?

RE: [RCSE] Re: TX RF output?]
No flame, just fact. Radios/RF decks (modules) still have tuning coils and the like. Just open up your radio or module and look at all the little parts with wax on them, that's what gets adjusted. We, Horizon Hobby and JR service center tune about 30-40 radios a day.

Wow, solid state, haven't heard that in a while. The TX does take a lot of abuse. Getting dropped, knocked around. Antennas get pushed and pulled all the time. (As anyone with a Vision may have experienced). The electronics are not in a sealed environment. There is dust, dirt, humidity, lots of things that can eventually find there way to the right place. Running TX with the antenna down might produce some extra heat on the RF output electronics. All the materials in the transmitter can age which affects thier performance. Plus mechanical problems like switches and pots wearing out. Of course, given the types of comments on this topic, there are lots of folks out there who just keep running things until they break. SOme people check thier batteries all the time, others never check them. It's no fun loosing an airplane to equipment failure. You just have to decide how much time you want to spend preventing equipment failures. Anyway, it's almost spring. Time to start checking out your models that may have been sitting around for a while. RCSE-List facilities provided by Model Airplane News.

The current draw is low, so NiMH cells will work just as well as NiCd cells, and with the added capacity, will last longer. Some simple math suggests about eight hours for the 1650 mAh cells -- basically all day. Your slow wall-wart charger will work just fine, but with a pack that's 3x as large, a full charge will take 3x as long. A fast charger will work as well, as long as it can do NiMH properly (and nowadays, most can.) NiCd cells do last longer (i.e. more years, more cycles) in general, and will tolerate abuse better (i.e. fast charging, or leaving it on the slow charger for weeks at a time) but the difference isn't that large. NiCd cells also handle high current draw abuse and vibrational abuse (more of an issue in glow plane RX packs) but for a TX, neither one is a problem. You can also charge NiCd cells faster (2C or so vs 1C) but I'd rather just not have to charge at the field at all if I can avoid it, so ... NiMH cells do have a larger (2-3 times as large) self-discharge rate, so after a week or two they'll be more discharged than a NiCd pack, but if you charge the night before flying, you won't have any problem. And so I make NiMH packs for my TX's nowadays in most cases, especially for my computer TX's that draw a lot more current than the old non-computer ones. -- Doug McLaren, [EMAIL PROTECTED] `The only time you have too much fuel is when you're on fire.'

Re: [RCSE] Re: TX RF output?]
You might consider asking a repair depot about how many TX's come in that are indeed emanating into adjacent channels. Secondly, RX's have interfered with each other in dual installations causing a loss of range, which on some installations has been severe. Using isolation techniques, the problem has been solved consistantly... Martin Usher wrote: What a novel and smart suggestion.

Re: [RCSE] TX battery - NiCd or NiMH?
Arne, I would suggest replacing your OEM NiCd pack with a higher capacity NiMh pack. I did it a few years ago and have been delighted. I can just about do a complete 2-day contest with my JR 9303 on a single charge. I am using the 1650mAh Sanyo pack built by Steve Anthony at hangtimes.com. The NoBS packs from Hangtimes cost a little more, but you are getting a top-quality pack. Remember, it's not only about the cells. Pack construction is just as important. Everything depends on your TX. A few extra bucks for the very best is money well spent, in my book. http://hangtimes.com/txpacks.html I also have a TX pack from Batteries America based on the Sanyo HR3U Twicell 2300mAh cells. This works fine as well, but it is apparent when you look at both packs that the Hangtimes pack was built to a much higher standard.

Re: [RCSE] TX battery - NiCd or NiMH?
In a TX, NiMH offers superior performance given the relatively low current consumption. On the other hand, NiMH is inferior on the RX side when current demands are high when compared to NiCD.

Re: [RCSE] Re: TX RF output?]
Actually without being as smart as some of you I can still disagree with this. Most radios do get out of alignment. I have been on the receiving end of splatter. A tuneup couldn't hurt. Receivers do emit RF. An ESL member has come up with a way of tracking a receiver based on its emission. He started with duplicating the Walston receiver using a Yasu and other Scanners. Then by playing around he noticed he didn't need a walston transmitter in the plane, that with many RX's he could actually see their output on scanners. While true not all receivers emit, most emit enough that he was able to pick them up. I received a couple of bumps at the nats, but I remember 2 guys being out of shift enough that they caused I think it was Daryl to go in.. about 6-7 years ago. When the scanners looked at their frequencies they were obviously off of their channel... enough to be a problem. Gotta run... my 2 cents.. probably all it is worth...

Re: [RCSE] TX battery - NiCd or NiMH?
True enough, Simon. But if you use large enough NiMh cells, there is more than enough ability to deliver the kinds of currents we need. I have always thought it was silly to see people using 4-cell AA or even AAA NiMh packs in big TD ships, then adding lead to balance. I always try to get as close as possible to the CG I want using batteries rather than lead. In the Pike Superior, for example, I use 4-cell packs of GP2200. WIth a JR R770 up front and maybe ~3/4 to 1 oz of lead taped to the side of the pack, you are usually right on the CG.

Re: [RCSE] TX battery - NiCd or NiMH?
Arne, Consider that the transmitter has very little pulse load requirements, that is, the current drain is relatively constant so cell resistance is a minor consideration. Therefore, the NiMH battery with its superior capacity at moderate current is a better choice. The only downside to NiMH is a higher self discharge rate. So figuring 2% per day, you loose a little over half capacity in a month. That is still three hours of run time left for a typical TX with a good safety margin. I was convinced a few years ago and it has been working out very well. Either way, you have run time for anything except a Level 5 slope attempt!

Re: [RCSE] TX battery - NiCd or NiMH?
Hi Jim, The most important specification to consider is the cell impedence. You might be surprised to discover that cell (larger) surface area in those bigger NiMH cells still does not make up for lower impedence within an even smaller NiCD cell. Add a larger (similar) NiCD cell and the lower impendence it offers and you can actually measure the available voltage difference at the servo when it is really needed...

Re: [RCSE] TX battery - NiCd or NiMH?
Yes, for sure NiMh cells generally have lower impedance. But we are talking about the GP2200 here. I routinely draw around 70-95 amps from these things in my 10 and 12-cell electrics. A TD plane, fitted with DS368s will draw a max of what, 5-6 amps? --Jim On Mar 8, 2006, at 6:13 PM, Simon Van Leeuwen wrote: Hi Jim, The most important specification to consider is the cell impedence. You might be surprised to discover that cell (larger) surface area in those bigger NiMH cells still does not make up for lower impedence within an even smaller NiCD cell. Add a larger (similar) NiCD cell and the lower impendence it offers and you can actually measure the available voltage difference at the servo when it is really needed...

Re: [RCSE] TX battery - NiCd or NiMH?
You bet Jim, great cells. In competition, the packs are first heated to ~50C to realize their full potential. It is at these temperatures and higher that they offer excellent voltage retention!

[RCSE] FS: Sharon 3.7m TD $875.00
I have a Yellow/Blue V-Tail Sharon 3.7m TD sailplane for sale. It has Volz servos throughout, RADS system installed on the ailerons. Hitec Super Slim 8 receiever, just pop in your crystal, program and go fly! It's that simple. This Sharon was purchased from Edgar Soaring Junkie a couple of years ago, I had a line catch on my first flight with it and I cracked the fuse and crinkled the very tip of the wings crinkled a bit, it was fully repaired and flown all season, I took 2nd in Sportsman at DVSS, 3rd Open at Gamblers Gala, top 20 at Vislalia 2004, it's a great flying ship and it's proven itself time after time. Pictures can be seen here: http://www.ferradasphotography.com/Sharon Asking $875.00 FIRM I can have this plane delivered to Davis or Fresno Classic if your seriously interested in buying it. __ Do You Yahoo!?

[RCSE] Re: TX RF output? and urban legends
the receiving end of splatter. This is mostly just that .splatter, not RF but conversation. OurRX's have ahuge problem...they are sooo selective they barely listen to their own frequencies, so the idea of them being bothered by some sort of close emission from a grey tuned TX, while 'possible' fact is the offending TX's emission would have to be aspowerful as your own TX's correct output so as to 'slur' your TX's frequency.. The reason for tuning your TX is so that YOUR RX can hear it, not to avoid someone else's RX from hearing it. However stories about getting shot down arereinforced by reports of off tune TX's makesthem more dramatic which equals 'real'. When in fact seldom is a 'shoot down' a shoot down, usually the cause is a faulty on board power connection...switch, or connector. Cases like the Nats problems are more likely due to on board antenna situations., or then there is the assumption that the pilots TX must be working just fine at the time of the glitches.Dirty antenna,a funkyrubber ducky install or it's sloppy BNC connector connectionor some other mechanical shortcomingcouldn't be :-) It is a lot easier and more fun to put the blame on the other and his probablyout of tune module, the mysterious 'them' are always the culprit.. The above is of course only a guess based on ..oh about a million hours of flying on sites all over the world, conversations with guys like Steiner and Marks on the subject, so take it all with a grain of, any way you want :-) Gordy Los Angles tonite
