开云体育Isn't Ameritron (MFJ) offshoring
manufacturing?to China, or only to Mexico?
I noticed that Icom partly produces in China, their
simple stuff like speakers and microphones carry the "proudly made in the PRC"

SB-200 Hi-Speed Switching Modifications
Bob
Has anyone documented the changes required to install a hi-speed
switching mod in a Heathkit SB-200 including a schematic and component values? I have one I would like to modify but I would hate to have to re-invent the wheel. Thanks and Happy New Year. Bob W6VY |

Yes, why not reward all these lazy people with no chance for anything better. Send all the factory jobs to China because they will work so hard for peanuts. Send all our software jobs to India because everyone knows software people just make it look hard. Send all our heavy industry to?Korea because they will work for almost nothing.......next time you have a war we can gather sticks and stones. BTW I know a fair number of engineers who barely stumble through life. They can't do anything so they create red tape. Talk about stumble through life look at the beltway! No problem just raise the credit card limit. We can't afford SS we have wars to start. We can't afford education..... Happy New Year! ky4sp wrote:

Re: AL80-A
I beg to differ; half my family works at Wal-Mart. It beats flipping
hamburgers by quite a bit. Of course they realize that having "a job" in itself doesn't guarantee that you will have a nice house, car and pocketful of $$ for the weekend. The fact is that many entry-level jobs simply are not worth the current minimum wage, if that. The middle class cannot afford to continue to support an ever-growing number of people who feel that merely managing to stumble though the day at work should make them a comfortable living.

My feeling has always been that Unions are for people who can't cut it on their own. I never needed someone else to fight my battles for me. GL, 73 ### Oh give us all a break ! With homes around here skyrocketing in price [>400 K $ ] the joke is.. most peoples homes are making more money per year than the owners. You can't survive on $8.00. Heck u can't survive on double that these days. Now u need both spouses working a 40 hr week to gets by... and both making huge bux. Ever worked for a non union jerk run outfit ? Those co's appear to charge the same for the end product... screw all their employeee's with crummy wages and no benefits.... then pocket the difference. in the future. I hear $8 an hour buys a lot of amplifiers. Bet you would love to join a union if you were making that big $8. I hear cutting grass is a good business to get into. How about flipping burgers? a while ago. We use to use them for rush jobs and they were cheap.I drive buy this little machine shop that went out of business Now we have to go far away and wait weeks ### It wasn't.. it was a dumb move on their part.. that benefitsexplain how smart that was. nobody. businesses than we can count by demanding more wages and benefits than the employer could stand, all with no regard for anyone but themselves. That's why I shop at Wal-Mart and admire them for standing up to Union pressure. ### That's almost laughable. By shopping at Walmart [btw IS the world's biggest jerk run non union outfit on the planet bar none], you are just screwing urself in the long run. My daughter worked there for a few months.... she was glad to get the hell out. applied by more American businesses, there would be a lot more of them still in operation. The basic strategy followed by the major manufacturing companies was "Give the unions whatever they want no matter how unreasonable it may be and keep the lines running. We will just pass the additional cost along to the buyers." money. ### Yes... and the way they do it.. is to buy bulk.. off shore... then if that isn't bad enough... then screw their employees over... and pocket the difference. "out sourcing" is nothing more than "contracting out". Just saw a documentary whereby the IRS was sending 500,000 tax returns to India.. to be processed. It worked so good that the following year they electronically shipped millions of em over. Then it went on to say that 22 state gov'ts now ship loads of stuff to India to be proccessed.. all sorts of standard gov't forms. They said within 5 yrs ALL US tax returns will be processed overseas. ## I predicted this years ago... and was dead on. This high speed electronic transfer of data... for fed/state paper work... including everything from tax returns to mortgages...to motor vehicle registration etc, etc.... amounts to the mother of one big world wide .. 'electronic sweat shop'... with no end in site. ## The latest is getting MRI's.. and CT's done in NA... then shipped overseas... where some underpaid Dr. will analyze it for u....dirt cheap.. then forward his finding's back. ## all as Walmart has done is jumped the gun. Now that nobody else can compete... they just follow suit... and buy off shore as well. ### CNN reported last year that the fed trade and commerce wasn't even keeping records of job losses to overseas. Now they are talking about making it a mandatory requirement. And these same jerk run outfits and co's want tax breaks, tax incentives, special treatment etc. ## saw another CBC documentary where they took hidden camera's into guadamala and costa rica... where expensive ladies clothes were made.... then shipped to 5th ave stores in NYC. The reporters had done some dumpster diving just outside the factory's... and found the paper work... depicting the exact break down cost to make each ladies blouse..... worked out to 2 cents a minute for labour... and they gave em 11 minutes to make each one ! The shipping cost were far more than the labour cost. And these items sold for as much as $180.00 US funds at Sach's on 5th ave. ## The living conditions of these worker's was 3 steps below deplorable. Unless you are willing to work for the same $1.20 per hour.... and the gov't allows co's to "outsource" overseas.... the union issue isn't even relevent here. Don't want to work for slave labour rates?? Fine.. we'll just..."out source" ur manufacturing job then. ### The same documentry depicted typ wage in China at 17 cents... per day ! Hundreds of workers were brought in from the country side... and had been working for several months.. and still hadn't been paid. With a Communist gov't running the show... and a load of serious fire power to back em up... stuff like unions and human rights just went out the window. Of course the smart guys in Hong Kong showed em exactly how to do it too..since they are all in the same bed together. I'm half expecting Hsu to come and blast us all. Perhaps he can tell us who he voted for in the last election LOL. ### I'll go out on a limb and say.... in 10 years... u are finished...toast. The middle class will be completely gone.... and there won't be enough of the upper class to pay for all this mess. ## someday... somebody will have to tune in.. and just say... if it ain't made here... u can't sell it here. Notice NO TV's have been made in Japan since 1987. Once India seems to expensive... China will be the next place to "do business". Once China is deemed too expensive... the workload will just pass on to the next 3rd world country... and the cycle keeps on going. ### Wanna work for Bill Gates ?? He pays a whopping $5 grand per year....... in India. Of course you have to be fully trained.. and have all the appropriate University degree's. If you don't like it after a while.... you can always just cross the street... and process Income tax returns..for the IRS. And people wonder why the crime and divorce rates keep going up.

My electrician buddy sez theye all use these new greenleehole saws instead of the greenleen punches. I had a look at a complete set down at home depot... in the green box of course.... they will cut steel, AL, anything. ## I also broke down.. and bought a complete set of ne greenlee punches from 1" up to I think 2.6".. I have all the small ones allready... like 1/2" 5/8" 3/4". The greelee punches these days all have bigger draw studs... since all new punches are of the "slug buster" variety... so have 2 x extra cutters on em to split the slug clean in 1/2. TIP:.... instead of busting ur gut using the supplied greenlee mega wrench.... use an air driven impact wrench instead. The hammering action works great.... way better. ### At work...all our green lees' use a hydraulic ram/ fluid set up.... which cost HUGE bux in their catalog.. as in hundreds. An impact wrench... either air or electric is the way to go. I too once had a need to whack clean 4" holes. So I punched "small" pilot holes for the draw studs... and borrowed the 4" greenlee and hydraulic ram. ## These days... I just use a Bosch jig saw... with the correct narrrow blade [think it was a T-225]. Bosh makes two kinds of jig saws.... mine is lower profile.. more like a long sausage.. lower to the table. The secret is the speed control.... u gotta slow it right down. I cut perfect 3.1" diam holes in 3/8" thick 6061-T- 6 aluminium plate... for my bearing plates for the tower... used with Rohn TB-4 bearing's. You can cut up to 3/4" thick AL with those Bosh blades... and pretty hard thinner steel too. I chopped perfect 6" diam holes in the top of a steel cab.... for the hot air exhaust on a 3x3 amp. ### Where the green lee punches come in handy is for small diam holes from 1/2" up to 2.5" diam. Anything bigger, use a jig saw. I have NOT tried these new far out green lee hole saws all the electrical guys are ranting about. You gotta run the RPM WAY down on those..esp a 4-6" diam hole saw on steel/al. A 4" hole saw has a 12" circumference... and all 12" is cutting and in contact with the metal. I think the 6" ones spec'ed a rpm of under 85 rpm. ## I use A-9 cutting fluid on AL.... regardles of either zirconium drill bits.. greenlee punches. etc. And the other glop.. cutting fluid... for cutting steel. ### greenlee also makes a combo drill/tap.. all on the same shaft.. so u can now drill and tap... all in one quick shot. The new greenlee taps are available in the mouser catalog. ### IMO.. greenlee has almost priced itself out of existence. A set of punches .. and 3 x draw studs plus box.. plus wrench was almost $400.00 here In Canada... and the complete set of hole saw's is abt $190.00 . ## U watch...next trick will be greenlee will relocate to china. My vetical/horizontal metal band saw... [sorta like a portaband saw on steroids] made by delta... was made in the USA... and my delta 12" heavy duty disc grinder was made in ...china ! So delta products are now no longer made in the usa either. .. go figure. company, et al, and being a radio tha was made in America happens when China comes to thepowerplants and they decide to### There was also a consolidation between gould, exide, et all for CO batteries in telco's... forget the name of the new fangled battery co. [flooded 525lb wet cells 2550 A hour types] In the last few yrs... we have had one dud after another. Install 24 of em... and 3 are bad.... replace just those 3....and 2 of those 3 are bad. Last week.... an entire string of 24 lasted just one hr [2550 Ahr types..] windstorm had knocked out the power... and diesel gen set wouldn't auto start.... batteries shoulda lasted 6-7 hrs. They all have this fine white crap on all the positive plates. The sealed gel cell type are internally arcing. yrs go u just installed em... and they ran for 20-30 yrs. These days.... it's install em... then they are either duds... or partial duds... or a few duds. We send em to the "battery dr" who rebuilds em.....then bills the manufacturer... under warranty. I have seen all sorts of bizzare stuff lately... white crap on the posts... posts half twisted where they enter the cells... green sulphide crap on the posts, etc. Their quality has gone from bullet proof... to some real manufacturing problems. These newer steel cased types.. forget what they are called... maintenance free... are packed with what amounts to steel wool soaked in acid. They started arcing internally.... and several strings had to be junked. ### For a real ;aff... check out battery connector's on chevy trucks... and also small ford cars. Instead of the usual heavy duty lead cased clamp assy... that pinches the batt post.... they all now resemble a paper thin hose clamp assy. The one on my wife's ford.. burnt right clean in 1/2 ! Had enough slack to install old style connectors... which will last forever. ## I notice that GIGAVAC brand vac relays.. made in china hi pot test to double what a jenning's does... and is way better built. The Gigavac eq of a Jenning's RJ-2C.... has threaded cylinders.. and silver plated machine screws on all 3 x RF connections [spdt]... a lot easier.. and a snap to connect wide strap to.... instead of trying to solder 8 ga wire on the inside of the cylinder. ### Gigavac, imo... builds a way better mouse trap. Of course...Gigavac is made up entriely of EX Kilovac R+D employees.... after TYCO bought out Kilovac... and booted out the CEO.... and entire R+D dept. Pissed off employees started Gigavac... and the plant is in china.. [brand new facility] . Story is... Jennings USED to have 80% of the vac relay market cornered...esp defibrilator's. ...and Kilovac had the other 20%. Kilovac managed to turn it around after years of hard work... and numbers reversed... with Kilovac having 80% market share. Then along comes Tyco... gobbling up co's right and left... and still building the exact same old stuff... no R+D dept any more. I hope Gigavac does well for themselves. ### Now all we need is to get somebody to build 7-16 din chassis connector's with the flat bladed back ends to em... that take transverse machine screw threads..and mating screws. This is great for terminating strap. TRU connector co makes em for LC connectors'... but not 7-16 Dins.... which seems'...silly. I mentioned it to em... and they wanted $2500 cash up front... + a min order of 1000 x chassis mount dins ! With an attitude like this.... it's no wonder co's are going belly up. They can't inovate their way out of a paper bag... even when u engineer it for em..... or they build defective sub standard stuff.. which costs em a fortune in under warranty costs. ### Rohn once made defective free standing cell tube towers... the typ 90-110' type. A few snapped off.... they ALL had to be removed ..and shipped back.. and replaced. These were working sites with traffic on em. And now u know why Rohn went belly up. That.. and making stuff like 45 g sections.. with holes drilled wrong.. where sections splice together. ## Can anybody actually build anything right anymore ?? Triton couldn't even build a 3-500Z... and gave up. [ they wanted $220.00 per tube too] later... and HNY Jim VE7RF

These ceramic doorknob caps of course are rated at 1 ,10, 30 mhz.... and the higher the freq.. the higher the RF rating..... which is just the exact opposite of a mica cap. Good... cuz the RF current through a plate block cap on high bands is just unreal..... due to the tube's anode to Grid C on a typ metal triode. This tube stray C, of course makes up most of the total C1 tune C.... and the plate block cap is between those two points..... trbl is... the plate block cap is on the wrong side of the tube's anode to grid C..... and plate block cap has a ton of RF current through it on high bands.
