Terrell wrote: The Daring Dufas wrote: Hey Mike, I worked out at The Kwajalein Missile Range back in 87 and 88, there was a lot of telemetry going on there, did you happen to be working in the telemetry field at the time? It's now The Ronald Reagan Ballistic Missile Defense Test Site, I think I know why it was renamed. There was some pretty cool stuff going on there back in the late 80's and I'll bet there is some even cooler stuff going on there now. And speaking of cool, there was a good sized sat dish with a cryo cooled LNA or LNB right near my living quarters. I loved it out in the islands. No, I was in that field in the late '90s and early '00s, until my health failed. Did you use any equipment from Microdyne? They were still supplying parts& upgrades for the 1100 series they built during that era. The 1200 series was still in production, along with the 700/1620 series, and the 1400 series. I worked on the launch of their RCB2000/DR2000 series to move it from prototype to production ready. I wasn't working on any of the missile systems, I was working for a contractor building facilities. The only electronic systems I worked on were the office phone system, the two way radios, any control problems, access control, Halon fire suppression system, of course, any of the guys having a problem with a TV, VCR or tape player asked for my help. I had to rebuild the voltage regulator for the 20kw gen set on our crew boat. I took it to the TV repair shop there on the island and found an FET from a TV that worked in the regulator and had the generator back up and running. The gen set ran a compressor for the air starters on the twin 12 cylinder supercharged Detroit Diesel engines. The smart ass captain liked to start those monsters when I was down in the engine room checking things out. I kept ear plugs handy, especially whenever I had to go to any of the power plants. I loved it out there and would have stayed if I hadn't been transferred to a 20 man housing unit that had 19 smokers living in it. That's like sharing a four bay room in Army barracks with three slobs. Luckily, most of my time after basic I had a one man room. It only took 15 minutes a week to keep it clean enough to pass all inspections. It was funny, at Ft. Rucker. I was an E2, but in a slot for an E5, so I managed to get the key for the assigned one man room. It was a real mess, and took about two weeks to clean all the old floor wax off the floor, baseboards and even the walls. A month later we were visited by a bunch of generals from Washington. One asked my captain who's room they were in, then said it was the cleanest he'd seen on the whole trip. When he found out it belonged to an E2 he got mad, then laughed and said, Anyone who spends enough time to keep his quarters that neat could keep the room. I barely spent 15 minutes a week. Luckily, he didn't see the coil of coax hanging outside my window. I worked in the Weathervision system, which included 17 Cable TV systems. The man that maintained the civilian cable TV on base gave me permission to run a drop to my room in the barracks when he caught me repairing the damaged drop to our dayroom. He figured that if I had cable, I would keep the two paid drops working for him. A friend of mine studied electrical engineering at Auburn back in the 1960's and lived in a dorm with a bunch of other typical college boys of the era, no coed in ancient times. The big thing at the time was the big AM station in the state playing pop music all day. When my friend wanted to sleep or study, he would switch on his low power AM transmitter he had hooked to the dorm's rain gutters and silence all the radios in the dorm. When he grew up, he wound up being in charge of the communications division of a major utility company. Later, I worked at a military TV station, before leaving the service. Years later I was an engineer at a UHF TV station with a 5 MW EIRP signal on a 1749 foot tower near the east coast of Central Florida. If you could get close enough to the antenna, you could cook hot dogs, in about a tenth of a second. I've tried to explain to a lot of folks that an AM station tower IS the antenna and it sits on insulators. I remember a couple of idiots climbing the TV towers around here. RF is so much fun to play with. 8-) One of the tower crew found the hairline crack in our waveguide the hard way. He leaned back against it and had a 12 inch long RF burn across his ass and lower back. There was about 190 KW of UHF RF (Ch 55) flowing inside that brass duct. It only took a few seconds before he felt it. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |

I preferred the B&L I had on my bench at Microdyne. Also, I liked the 'Multicore .015" rework solder. Surface mount isn't going away for small parts. A look at the Digikey or Mouser catalogs over the years will show that the availability of leaded parts is dropping every year. The same, with components using real solder without tin whisker problems. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |

And nobody sees a basic problem with design philosophy here? Control circuits for an HVAC system need to be closer to an anvil, than to avionics, to meet design lifespan if nothing else. Sigh. It would be great if HVAC electronics were built to Avionics standards. For one thing, Avionics is 100% exempt from lead free solder. For another, equipment design is always at the 'Mission Critical' level. Avionics are built for long life, with little or no maintenance. It is usually there for the life of the aircraft, unless that series undergoes an across the board redesign. Of course, it would double or triple the retail costs of the controller. One thing I've seen in a lot of failed programmable thermostats is that they use slide switches that are installed before the boards are cleaned. Then the board cleaner washes out all of the contact lubricant. And they need to be field-repairable. If it can't be at component level, there needs to be an industry standard for board interfaces and mounting, so that the unit cost of boards can be low enough to repair at board-swap level. (Yeah, I know, there are always plenty of standards to choose from.) How do you propose to do that? If you make an interface to handle any possibility, you add a lot of costs. Surface Mount is actually easier to repair, if you know what you are doing and less susceptible to board damage if you know how to solder. If you are a hack at electronics, then all bets are off. I know nothing about HVAC beyond 'no worky - pick up phone'. But I have worked in computers at the field support interface for 20-some years, and have run into similar issues. Engineers in that field violate KISS principle on a regular basis as well, and component level repair vanished years ago. Strange, because I still repair some motherboards. A lot of failures are bad low ESR electrolytics, or cracked ROHS solder joints. Until I ended up 100% disabled, I repaired 68340 based embedded controllers at the Microdyne factory. I also tested and repaired all of the boards in our dual receiver DSP based RCB-2000 telemetry products. Contrary to popular belief, having schematics isn't always a help. OTOH, having the datasheets for the ICs is. A lot of techs have no idea why some things are done. For instance, I see people bitch about 'Those morons put the electrolytics too damn close to the CPU! Why can't the *******s put them on a corner of the motherboard, away from the heat?" Well, they carry a high ripple current, so they are self heating. The CPU us a high current, low voltage device, so the regulator has to be close to the load. Long traces would radiate a lot of EMI. A lot of power would be wasted heating the copper traces, and the inductance would screw up the regulation. Buy a ESR meter and test the electrolytics on those boards. A little ripple can cause all kinds of problems. 30 years ago I was doing bulk repairs on 'Linear' brand garage door opener controls. Every one of them needed new electrolytics. They were always mounted in hot locations, and powered 24/7. Similar to the environment in HVAC systems. One thing that makes it hard to repair those boards is that the techs don't use logical troubleshooting methods. They use hunches, or just shotgun a board till it starts working, or they destroy it with sloppy soldering or installing parts wrong. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |

I don't see that much surface mount on the majority of HVAC control boards. I haven't seen the latest supercalafragilistic uber-efficient HVAC system control boards but the simple ones are mostly single or dual layer with components having leads soldered through holes. I don't have customers who can afford that really high end stuff for their homes. even the 13SEER condensers and heat pumps that I install have mother boards in them, as do the gas furnaces I install. Lots of surface mount stuff, double layer boards, optical latching relay instead of a contactor, serial controlled, etc. Is there a particular brand you install? Me and GB have been installing Goodman and to tell the truth, I haven't bothered examining the darned circuit boards on the newer stuff we install. We have a buddy who's a Standard dealer and he charges a pant-load for his gear and $100/hr. I don't do anywhere near the volume of HVAC work you do so I'd have to defer to your experience. Hell, I was so tired when I got in today, I couldn't stand up for long and had to postpone fixing a leak on a very old Carrier heat pump. I know that sucker has no surface mount devices on its control board, it's older than the girls chase. 8-) I install the Rheem "Prestege" -JEZ series almost exclusively for both A/C and heat pump condensers. My entry level systems use a 13SEER condenser, but with the correct coil and air handler/furnace combination, the system is rated 14SEER or better. My "premium" systems are 16+SEER, 2 stage, serial controlled systems. FWIW, I have not installed an R22 system in 5 years, only R410a. Me and my homey works fo mostly po folks dat doan has a lots O money. We found a new 3 ton R22 heat pump condensing unit at Johnstone this Spring to replace an old unit for a customer who's air handler and evaporator were in good shape. This Summer, we replaced an old R22 system for a friend with a new R410a system and we darn near toasted to death. It was in the middle of the hottest Summer we've had in a long time with temps in the 100°+ range for many days without end. I didn't have to pee for 8 hours, it all came out of thousands of tiny holes in my skin. 8-) TDD |

Go real easy on the sodas tho... they will dehydrate you faster. Back in 89, I was working in a plant under construction in The City of Industry (some of you know where that is) and the temperature was 105° and the humidity was nonexistent. I was bone dry, even my underarms were dry. The breeze blowing in from the desert felt like a hair dryer. And here people have been wondering why Ive been doing work around my homestead from dark till dawn.....

Ouch, that's a lot of water. And fluids. After chugging two liters of

Stormin Mormon wrote: I'm glad you had the water available. Is it possible you were dehydrated before you began the day? No. I started early in the day, when it wasn't too bad out. I had the cooler I carried when I spent the day at a flea market, which included the refilled two liter bottles that were kept in my freezer. There was also a 10 pound bag of ice and a two liter bottle of Diet Mt. Dew. I drank all ow them, and used my tee shirt in the ice water to lower my body temperature.

Isn't that the way. Even after real life dentistry, they won't write a
Rx. I've had different dentists, some will write, others will not. -- Christopher A. Young Learn more about Jesus www.lds.org .. "aemeijers" wrote in message ...

I'd hate to think what would happen to a tech who drank only Mt. Dew.
That could make for a poor night sleep. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Michael A. Terrell" wrote in message ... Stormin Mormon wrote: Ouch, that's a lot of water.

So why wouldn't they give you any meds? It was an emergency, and the moron Lt. he was replacing was too sorry to restock the clinic at the small Army base in Alaska. There was nothing to prep me for surgery and nothing to prescribe for pain killer afterwards. The fronts of two teeth broke and fell out while eating lunch in the mess hall on a friday, and I had to wait three days for the clinic to open which was only open on Tuesdays & Thursdays. The alternative was a two hour ride on an army bus to Fairbanks on a mostly gravel road that was painful to ride when you were well. I came close to killing the idiot Lt. when he suggested waiting another day for a ride in a helicopter, which was rougher than the damn bus ride. So, I sat there as the Cpt. used what looked like a large Scratch Awl and some pliers to break apart the roots and remove them one at a time. What was left of the crowns crumbled as soon as he tried to pull either tooth. He kept stopping and asking if I wanted him to continue. I would nod, and try to say yes. As far as pain killers after dental surgery, I didn't start having the prescriptions filled until a few years ago. I've had eight teeth cut out in the morning, and went on to work a full eight hour shift later that day. It wasn't till I became Diabetic that I had to give in. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |
