Message-ID: <20031222002619.CZVD11001.tomts28-srv.bellnexxia.net@smtp.bellnexxia.net> MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 7bit Hi: I have a few 7AH and 17AH SLA Batteries that are not holding much charge. I thought that I'd take a look at the fluid levels. I popped off the plastic cover, then removed the 6 rubber plugs. All the batteries appeared 'dry'. Even when I tilted them, I couldn't see any fluid. I then added distilled water to just over the plates. There didn't seem to be much space above the plates, and, sure enough, when they were charging for a while, they leaked out. Fortunately, I had them sitting on a plastic shoe tray. Also, I found that you have to secure the plugs with the plastic cover plate, taped down. Those little plugs do pop quite far! Apparently, these batteries do NOT contain much water. SO, my question is "Is it worthwhile to 'top up' these batteries, and 'How Much' distilled water should I use?" If I weigh the battery at the start, can I use the Printed Spec's and then add water to bring the total weight up to the Spec's? Or is there another way? Or should I quit before I splash acid all over things ? 72 Mike VE3EQP.....> ------------------------------ Date: Sun, 21 Dec 2003 19:36:42 -0500 From: "Brian Murrey" To: "QRP-L" Subject: [163521] Homebrewer #2 Message-ID: <004f01c3c823$ac507370$02fea8c0@bjmw2k> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Anyone know if Homebrewer #2 has shipped yet?

I'm looking for a guide or book covering basic circuit design, from the ground up, with practical design projects and examples. The ARRL Handbook, which I have, is a good source of information, but not as structured as I'd like, and not very much focused on basic design. Looking at the ARRL Website, I saw "The Electronics of Radio" (http://www.arrl.org/catalog/erad/. Can anyone recommend or disreccommend this book, or suggest anything else, either in print or online? I'm really looking for something that would be used in a class kind of setting, as opposed to just a reference book. Anyone have experience with this kind of thing?

I read it nearly every day in the archives and have learned a lot from it over the last year. Over the holidays I'll be putting together a PAC-12 antenna kit, with coils for 40, 30, 20, and 15 to match my K1. (My portable antenna farm will then be fully populated, with the PAC-12 vertical, a Norcal doublet, and a modified W3EDP inverted L, plus an N0SXX Mountain Topper II as a second vertical.) I've already built two homebrew H-stands for the PAC-12, a lightweight one made out of three sections from a heavy yardstick, and a heavy one made from 1/4" x 1" aluminum bar. (The antenna is supported on a 4" stainless steel carriage bolt with both of these stands, and they break down for transport.) I'm thinking about how to build a lightweight capacity hat for the PAC-12--any suggestions are welcome. Also, thanks to Richard Meiss for recommending the Sears underseat tool box as a carrier--it is perfect for the PAC-12 and is only $5. (One could fit a KX-1 in there, too, but I haven't taken that plunge yet.) Otherwise I'll be puttering around the shack and shop--installing a new chip for the Z-11, finishing up a PSKMeter for a ham buddy, reading selections from the 2004 ARRL Handbook I got as a present, etc., etc. I hope I'll catch some of you on the air while I'm off work, too.

Both used six 8' radials (made from ribbon cable) that came with the kit and the results were good (using my MFJ-259). I turned out the 20-meter coil, but the best VSWR I could get was about 2.2:1 over approximately 30 KHz. When I added four 16' radials the VSWR dropped to 1.9 over approximately the same range. The 40-meter version was centered on 7030 KHz and according to spec (approximately 100 KHz at less than 2:1). The 10-meter version was very pbroad banded -- less than 2:1 across 90% of the band as one would figure from an 8-foot vertical with six 8-foot radials. By the way, if you have a mind to, it shortens nicely to be used on the 6-meter band. Also, a question on the coils: I ended up with a 40-meter coil of 49 turns (26 uH) and a 20-meter coil of 15 turns (5.7 uH). Measurements taken over moist ground (it had rained the night before). James recommends 58 and 18 turns respectively/ I understand the concept of YMMV but I wanted to ensure I wasn't wandering off path. Great (and convenient) kit. 72 and thanks in advance.

Outside the tube floats a doughnut containing magnets that trip the reeds one by one. Super reliable. Dirt simple like me. Of course the resistor chain wires (2) are brought out through the top of the tank thru a fitting.

I noticed the same and considered removing a few turns.... until I discovered that all I had to do to adjust to resonance was to shorten or lengthen the the collapsable whip.

Anyone have experience with I have a copy of The Electronics of Radio and it has been useful for me, but I got way-laid with getting into it because of my lack of a NorCal 40A kit and at the time my lack of test equipment to actually follow along with the labs as laid out in it.

But if it's pressurized and the pressure may change, a DP measurement is typically used, taken from the top and the bottom of the vessel. Subtracting the top pressure from the bottom pressure gives the head, which is proportional to level. Assuming of course, constant fluid density which may also imply reasonably constant temperature. The device for doing this is typically called a "level transmitter" or "DP transmitter" and has an output of 4 to 20 milliamps for a certain span of DP, which is adjustable. A factor that goes into the calibration is whether the tubing going to the top of the tank is "wet" (full of fluid) or dry. This scheme can work for corrosive fluids if the transmitter and tubing are of the right material, typically stainless. But maybe some type of plastic would be compatible for the sensing lines (tubing). Sometimes with corrosive fluids, I'll also see a diaphragm isolator, which is in-line in the tubing. It has the bad stuff on one side of the diaphragm and typically glycerin on the other side. Pressure is the same on both sides so the transmitter doesn't see the bad stuff. One scheme I've seen for really corrosive stuff (sulphuric acid) is a "bubbler tube". Only works for vented (open) vessels though. A tube goes through the top to near the bottom of the tank. An air supply is connected to a tee at the top, and a valve is adjusted so that bubbles just barely come out the bottom when the tank is full. In this condition, the pressure being supplied is equal to the head of fluid, which is proportional to the level. A gauge connected to the other port of the tee is used to read that pressure and may be calibrated in level units. I've also seen some ultrasonics, which bounce a signal off the top of the fluid, I think, in the manner of sonar. The weirdest scheme I've seen is for reactor vessel level measurement, which was mandated by the NRC after the Three Mile Island accident. A probe goes in through the top (head) and down through the core. It contains differential thermocouples, which are actually two thermocouples in series, which the junctions spaced by several inches. The polarity is such that the voltages cancel to zero when the temperatures are equal. Oh yeah, the probe also contains a heater. So in an event when level is dropping, the upper junction will be uncovered first and the differential T/C will show and output because steam is a much poorer heat transfer medium than water. A microprocessor is keeping track of all this and sets a flag when it detects the condition. OK, I guess I've told everyone much more than they wanted to know. Or as Bubba said in Forrest Gump, "OK, that's all I know about shrimp." 72--Nick, WA5BDU -----Original Message----- Hi All, Thanks for the BW. Does anyone here have any experience measuring tank levels remotely? This is a corrosive fluid under about 40ish psi. 73, Ron, KU7Y ------------------------------ Date: Mon, 22 Dec 2003 06:15:50 -0800 (PST) From: Lloyd Lachow To: "Li'l Piggies" , a low-energy group Subject: [163554] what part to use?

From what I can gather in the "old days" from looking at my old ARRL Handbooks, a lot of ops used big double knife switches. They were effectivly big DPDT switches with the feeders from the antler connected to the center lugs and then the other set connected to the rig and to a ground respectively. However these were _inside_ the shack. I think you are looking for a totally "outdoor solution" tho... Cheapest route I would think would be to use a set of Anderson Power Pole connectors spaced appropriately on a small piece of plexiglass. Use some small nylon ties to anchor them down onto the plexiglass. I would go that route as it is pretty inexpensive. Not sure how weatherproof that would be, I guess you could tape it up. 72 es oo Dennis - WB0WAO EN84ij Iosco County, Michigan MultiPig+ #3 - K2 #3555 DSW-II-20 - SW-40+ - SW-30+ RM-20 - RM-40 FPQRP #-347 FISTS #9299 Charter Member - Michigan DX Association www.wb0wao.com :=) _________________________________________________________________ It s our best dial-up Internet access offer: 6 months @$9.95/month.

Under the eves of the house on my porch deck I have a large railroad lightning arrestor (don't ask me where I got this; I don't remember) that has dual discharge points, so each leg of the copper open-wire line is protected with a spark gap. However, the 5-way jack is mounted a few inches away and mates with a jack bar that has two banana sockets mounted on it. My feeder has a halyard connected to it as well, so when I'm not on the air I simply reach up, unplug the jack bar, and let the feeders swing far away from the house, where they touch the ground. When I want to operate, I haul in the swinging loose feedline using the halyard, then snap the dual banana plug into the banana socket assembly (which is mounted on a strip of FR-4 glass epoxy board), and away I go! The plating on the banana jacks and plugs seems really good, as this has been up there for years and there's no apparent corrosion or even discoloration of the separable components.

One of the categories which has enjoyed an increased participation over the last few years has been the QRP category. The members of the QRP-Canada mailing list have sponsored the QRP plaques for this category for the last 5 years and have just raised the funds for the next 5 years. The plaque goes to the Single Operator who operates on all bands and combines SSB & CW for the highest score. A number of e-mails have been posted on QRP-Canada promoting a desire to recognize additional QRP categories. Therefore, QRP-Canada, starting with this year's Canada Day contest, will run a contest in "parallel" with the RAC Summer & Winter events. All you have to do is operate in the RAC Summer & Winter contests, as you normally would. When each contest is over, just submit a Summary Sheet (example below) within 30 days of the contest ending to: Bruce Rattray (VE5RC+VE5QRP) 128 Durham Drive Regina, SK. S4S 4Z2 Canada ...or e-mail to rattray@accesscomm.ca After the scores have been checked, an announcement of the winners in each category will appear on the QRP-Canada mailing list and also in the TCA magazine.

I also had the pleasure of working Seab last night at 0425z during a short break from NFL Football. Snagged him just after his QSO with Guy VA2SVP/qrp in Ste-Croix. Glad he was able to copy my fist as I was using my miniture Whiterook MK-22 straight key. Luv dat key.

For QRP there is little to worry about current-carrying capacity, but for 1.5 KW I would be concerned with ladderline since the peak current is sqrt(SWR) times the matched current.

It seems to run 20 watts cw or ssb without heating up at all with the big heat sink on the back. It SUPPOSEDLY does PSK-31 but I'm not into that so have no information on how it does there. The qsk is classic tentec! With a twist as you can set the VOX delay and that also gives you delay in QSK ! Large contest signals will bother the radio even with the ATTEN cut in. PBT works on moving the qrm off the station you are listening to with the DSP filter set to 200 Hz. Seems effective. NB is NOT NR and seems do NOTHING other than cause distortion from nearby loud signals, now it might work if you had ignition noise but I don't have that here in the home station. The display is big and easy to read. The last 0 stays on uselessly all the time and is annoying but I suppose you could put something over it like one of those black sticky thing over the cut out on big 6" paper floppies in the dark ages. The 6 Kc audio on the BBC sound absolutely stunning into a LARGE 12 " speaker and there is plenty of audio drive. The ANALOG meter is a nice retro change. No menus to panic old timers. Just push and hold buttons. SSB reports have not been stunning but the only guy I talk to on SSB is almost stone deaf so his reports are TOTALLY UNRELIABLE :-) ............. you say no 100 watt rig but ................ The IC-746PRO on sale for $1329 some places and $1400 others with a free power supply and shipping is a option to look at. For a few more dollars you get a whole lot more radio. Bigger though but it does have DSP NR that works and also AUTO NOTCH on SSB , built in ATU and 32 BIT DSP which works a whole lot better than the 16 BIT DSP in the ARGO ! My argo has the $50 temperature compensator. So $875 for agro, plus $125 for a switching power supply and another $149 for a AUTO ATU and you have $1150 so for $250 more you get a lot more radio. Oh, the 2010 thing is just an upgraded QRP PLUS black box and the thing has rotten qsk with a CLACKY RELAY , a buddy got one and you must put in delay or it drives you nuts and the 706 / 703 have poor keying also with there clacky relay. The argo and 746 have quiet and fast genuine QSK if that is a big thing for you ? So , there you have my ramblings .............. look up all the reviews in QST :-) they tell it like it is !

Let me add a bit more to the selection criteria. I'll have little time to play radio for the foreseeable future. After being laid off earlier this year, I worked a succession of jobs, that has evolved to 40 hours/wk at a local hardware store; building/fixing rigs; at home production work for a small electronics firm; and in Jan I will start teaching an Algebra class at the local CC. 50-70 hour work weeks are the norm. [Very] little time for radio games. When I find some spare time, I seem to chose riding my bicycle first, radio 2nd. So, I want to scale down the shack [considerably] and free up some cash. At best I'll work a few QRP contests per year, and have the odd PSK rag chew with some friends. My [idealistic] goal is one radio to handle it all--CW/PSK/SWL and AM-BCB. The reality may be 3: A GE SuperRadio for AM/FM; My DSW-II/20m for TTF/HB contests; and the "TBD" for PSK/CW... general use. 73, Rod N0RC ...being ridden hard, and put to bed wet!... :-) **Happy Holidays** ----- Original Message ----- From: "Rod N0RC" To: "Low Power Amateur Radio Discussion" Sent: Monday, December 22, 2003 10:50 AM Subject: newer simpler rig for me, but which one? > Folks, > > Now that I sold some gear, and have some deals pending on the rest, it's > time to settle on the new rig.

After reading your post, I fired up the IC-703 on 14060 CW and worked John, K7UP, in Las Cruces, New Mexico. East/west condx don't seem so good on 20 today (though, W1AW was 20 over here a while ago)but John & I still managed a nice 10-minute chat. I looked thru my log and discovered that the last time I had used the '703 was 26 October...VE6, VP5, V31, VO1, CM8, KP3, FY5, 8P1 etc. In semi QSK, the IC-703's keying is 'ok' I guess, but its full QSK is not even in the same ballpark as any Ten-Tec rig. 'Nowadays', I mostly use the '703 as a signal monitor but it's good to know that the transmitter still works after I replaced the driver transistor back in early August. Knowing what I now know about the IC-703, I would definitely buy one again. Have made many contacts on CW, RTTY, PSK31 and (ugh), even sideband with the '703 :0). Still haven't tried AM or FM. I use the InRad 400 Hz filter for receiving the digital modes BTW. Good luck in reaching your decision! 73.
