Re: [AMRadio] MCM Electronics digital multimeter for $2.99
I think you mean it as a resolution of .001 volts. Accuracy is indicated as ±(1.5% + 2digits), which is still pretty accurate. Although unlike larger DMM's I doubt it has internal adjustment to recalibrate, so stability of that accuracy is really undefined. For our ham work it's a good deal at the three dollar price though. 73 Don N9OO Pat Bunn wrote: > And since it's digital - its accurate to .001 volts. > > Probaly as good as my $350.00 Fluke > > > > - Original Message - > From: "ken" > To: "Discussion of AM Radio in the Amateur Service" > > Sent: Wednesday, September 23, 2009 4:47 PM > Subject: Re: [AMRadio] MCM Electronics digital multimeter for $2.99 > > > >> did you mean $10.49 ? >> >> >> - Original Message - >> From: >> To: >> Cc: >> Sent: Wednesday, September 23, 2009 4:32 PM >> Subject: [AMRadio] MCM Electronics digital multimeter for $2.99 >> >> >> >>> MCM Electronics has a cute digital multimeter for $2.99 >>> >>> http://www.mcmelectronics.com/product/72-7940 >>> >>> >>> Steve WD8DAS >>> >>> sbjohns...@aol.com >>> http://www.wd8das.net/ >>> - >>> Radio is your best entertainment value. >>> - >>> >>> >>> >>> >>> >>> >>> __ >>> Our Main Website: http://www.amfone.net >>> AMRadio mailing list >>> Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ >>> List Rules (must read!): http://w5ami.net/amradiofaq.html >>> List Home: http://mailman.qth.net/mailman/listinfo/amradio >>> Post: AMRadio@mailman.qth.net >>> To unsubscribe, send an email to amradio-requ...@mailman.qth.net with >>> the word unsubscribe in the message body. >>> >>> This list hosted by: http://www.qsl.net >>> Please help support this email list: http://www.qsl.net/donate.html >>> >> __ >> Our Main Website: http://www.amfone.net >> AMRadio mailing list >> Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ >> List Rules (must read!): http://w5ami.net/amradiofaq.html >> List Home: http://mailman.qth.net/mailman/listinfo/amradio >> Post: AMRadio@mailman.qth.net >> To unsubscribe, send an email to amradio-requ...@mailman.qth.net with >> the word unsubscribe in the message body. >> >> This list hosted by: http://www.qsl.net >> Please help support this email list: http://www.qsl.net/donate.html >> > > __ > Our Main Website: http://www.amfone.net > AMRadio mailing list > Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ > List Rules (must read!): http://w5ami.net/amradiofaq.html > List Home: http://mailman.qth.net/mailman/listinfo/amradio > Post: AMRadio@mailman.qth.net > To unsubscribe, send an email to amradio-requ...@mailman.qth.net with > the word unsubscribe in the message body. > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > > __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] Receiver Noise Reduction Devices
Hi Mike, Is it coming in via the power line? If yes, the 1025 or 1026 won't help. If you have a battery operated receiver and you still hear the noise then it's radiated noise and in that case the 1025 or 1026 should be able to remove such noise. 73 Don N9OO Mike Duke, K5XU wrote: I'm looking for a way to reduce a received noise which is being back-fed into a nearby powerline from something inside a house about a block away. I've been working with my power company, and we are in agreement that it is coming from the owner's side of the meter. This noise is killing all but the strongest signals on 160 and 80 meters, and is almost as bad on the lower half of 40. The noise sounds like a strong white noise on 80 and 40, and more like an electric motor on 160 and the AM bc band. Will a device such as the MFJ 1025 or 1026 reduce this noise enough to be worth spending the money for it, or should I just prey for lightning in the next block?

Re: [AMRadio] USPS Changes May 14
Hi Bry, I do a great deal of Priority Mail shipments. The nice thing is the USPS allows me to do everything on the web and even schedule for the mail carrier to pick it up when they deliver the mail. All the Priority mail boxes are sent to me "free of charge" (packs of 25 boxes) also via web order. So with all the down sides, especially those I read about the overseas Global Priority mail, the USPS has made something very easy for the shipper. Note, that anyone can use these services. So it's been a long time since I've stood in those lines. Now I just need to do some research on what direction I'll be going with my international shipments. 73 Don N9OO Bry Carling wrote: USPS has been going to hell in a handbasket for some time now. They just get worse and worse. I tell them they should bui;d another post office nerar us so we won't have to CONSTANTLY wait in line for 30-35 minutes. They ignore me. I would pay 50 cents for a stamp, but really they are so messed up it is pathetic. Thank God for FEDEX! As you know I ship a lot, so it is interesting to me the changes that USPS is putting in May 14. Rate increases on everything of course--that's standard. But their parcel post service is actually changing quite a bit. Foreign surface mail shipping has been eliminated. It's all air mail as of May 14th. That should really cut down on the number of boatanchors crossing the pond. Global priority mail is now limited to 3 ounces. That kills the best way to ship small parts, mics and accessories overseas inexpensively. Parcel Post--ALL packages now have to be measured and are charged more as size goes up--not just weight. That should certainly drive a lot of shiping into UPS/FedEx camp. There's many other small changes. If you ship a lot, you probably ought to visit USPS.COM and check it out. 73, Don Merz, N3RHT __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body. __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body. __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

Re: [AMRadio] Experience with Ocean State Electronics (PICS)
Hi Mark thanks for the nice reply, and those from the many others as well. John KB6SCO did point out the notice they recently added to the website under "Contact" that indicate they had a major crash of their database computer and are working to restore and catch up. It does indicate a "family" business in the notice so your right it's probably a one man deal most of the time. Since I received an order confirmation email the site notice indicates I will be getting my stuff eventually. Still it was a bit unprofessional to basically shut down the email and they could have broadcasted their problems on the phone voice message instead of just saying "We are Closed today". If they attacked the notification of the computer crash and catch up via several avenues it would mean a great deal less people trying to call them and wasting more of their valuable catch up time. I completely missed the notices as they don't appear on their main webpage and were probably added after my last check of the site to confirm the email address and phone number. Yes the golden days of radio stores is just about all gone. Here in Kenosha, Wisconsin we still have Chester Electronics which has been around for a long time. They occupy an old grocery store. Chester's still have old TV parts from the 50's and 60's hanging in display. All those old sand coated power resistors and twin-lead antenna items - it's a real hoot to pass by those! I've been able to find those last minute BA parts like wire wound resistors and caps too. You just ask them and they disappear into the back and come out with the part in most cases. They also have the newer NEC semiconductor substitutes all along one wall. Those have come in so useful when I repair some recent vintage electronics equipment. I noticed now they have a store in Florida. I did notice the "ol-man" wasn't around the store in the past couple of years so my guess is he's still playing store keeper down in FLA. Most of the sales guys that were at the store when I moved here 19 years ago are still there behind the counter. I think many of them are family or extended family. Almost all the radio stores I visited in my youth in Milwaukee are now gone. The only one remaining is AES which isn't much fun for the BA collector. If I hit AES it's but once per year maximum. Thanks again about the insight on the Ocean State operations. I hope they do well enough to continue for a long time to come. I sure wish they'd bring back the SW-3 coil forms. Man I should have bought a bunch of those from them when they had'em. 73 Don N9OO W1EOF wrote: Any of our RI area BA'ers have contact with them? I do. I went down and visited them... I think it was about 16 months ago. It's a very small place. Not really setup for walk-in business. I rang a doorbell on the side of the building. After a few minutes a guy came to the door and said "come on in." I told him what I wanted and he went and got it. Lots of aisles with shelves to the ceiling. It's pretty much most of the building in the pictures. Stuff stacked up EVERYWHERE. A very busy packing bench. Piles of boxes ready for the UPS guy. Looks like a one man band to me. He was polite, but not very friendly. I'm guessing he didn't want to encouarge me to come down and hang-around the place. (*) He came back out and had some MPF-102, a few other things but the cast LMB box was "on back order." I don't think there was a back order exactly. I think it's just he cannot afford to have everything in the catalog in stock. There has been complaints with this operation since I can remember. I've heard lots of complaints about late shipments, but never someone getting ripped off. I acna guess he has two problems: 1. It's a one man operation so he gets behind at times. (small) 2. He is running things on a shoestring and has cash=flow problems (large) Been there. The more successful you are, the bigger the cash flow problem. It's a tough one. In my opinion charging peoples credit cards and then not shipping is unacceptable. Not answering emails or the phone makes matters much much worse. I'll bet it's because he does not have a good answer for you. You will get your parts when he gets his money and then he can order his parts. So I'd say be patient.
