However, that doesn't seem to be how this one works. Checking the prescaler chip from the photos, <http://img.yunqudao.com/UploadFolder/4f2543ab-bfc8-48f0-9aff-c49e51612b75/Default/40_6.jpg> I find a Fujitsu MB501L prescaler: <http://pdf1.alldatasheet.com/datasheet-pdf/view/61659/FUJITSU/MB501L/+4155-UwSHHTTVdRhCtYT+/datasheet.pdf> That's a 64/65 or 128/129 prescaler for a dual modulous synthesizer. I would guess(tm) that the eBay counter would use divide by 64 to get: 2400 / 64 = 37.5 MHz which is too low to utilize the full 60 MHz counter range. However, there's a problem. The MB501L prescaler is only rated to 1.1GHz. How they claim 2.4GHz will remain a mystery. If I had this counter (and a clean workbench), I would probe it to see what they're really doing. I couldn't find a schematic. There are some handheld counters that count to 60Mhz, and use a divide by 40 prescaler, which results in the proper frequency ranges: 2400 / 40 = 60 Mhz However, I can't find an example right now. The 40 is achieved with a divide by 4 followed by divide by 10, which I guess qualifies as a decade prescaler of sorts. As I recall, it was usually done with 2 ECL chips, which sucked plenty of power and were not cheap. Here's another way to use a prescaler: <http://www.startek-usa.com/FREQ%20CTRS.htm> The frequency ranges are: 50MHz, 800MHz, and 2800MHz which correspond to: /1 /16 and possibly /64 Sorry, but no schematic or block diagram found. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I couldn't find any such project. I suspect that it might have gone the same way as the various M328 component test meters being sold online. The original project was open source. It was then commercialized by various vendors with wildly varying pricing. Much of the stuff I've found was early versions of the board and firmware. Meanwhile, the project has done on to add features and improve the firmware, but the online stuff seems stuck with early revisions. This link includes some history: <http://www.instructables.com/id/AVR-Transistor-Tester/> I can't seem to find the original development site, which was in Germany. >and before the main counter, with the inputs paralleled.

If the amplifier is used to simply produce a square wave out of whatever it fed into the input, low gain might be a big problem. So will noise around 0v which is why a "threshold" adjustment is usually supplied. Getting such a simple amplifier to work from 0.1MHz to 2.4GHz is unlikely, which might explain the lack of sensitivity. >manual gain control.

May I suggest that you remove the input amp and setup something that give the prescaler a 50 ohm input. Then, design a broadband RF amplifier that has a chance of working over the frequency range. Something similar to a CATV or OTA TV/FM amplifier might be suitable. However, don't worry about getting a flat frequency response. Just take whatever you can get that produces enough drive to make the MB501L prescaler happy. A collection of communications freq range bandpass filters would be nice to prevent triggering on out of band junk. >The main counter is a PIC.

Yep, service monitors are a good thing to have an use, especially in the field or on mountain top radio site. It has everything that you might need to work on radios including a counter. All have TCXO or OCXO reference oscillators for accuracy. At home, I have a home made GPSDO for even more accuracy. However, there's a catch. All the stuff in the photos is from the 1980's which means that components are starting to fail. It's a continuous battle to keep these things running and usable. If you decide to invest in an older service monitor, be prepared to occasionally dive in and do some repairs. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

For the price, and considering the specifications, I just took a chance in the dark (literally), since I drove to a local WIFI at midnight and from my car, I bought it. I had a feeling it would be sold if I waited until today. I did find one of those discussion groups on the web, in which they were discussing it. Some guy bought one (on ebay) for around the same price I paid, and he was pleased with it, but did not know how to use a lot of the features and controls.

Google for Sanjian Studio (which is on the PCB) and you'll find an English translation of the manual.

Just curious, is the manual a series of images of pages or is the text selectable? I received a PDF document of an old PDP-11 listing from someone who wanted help typing it in. I realized when I clicked my cursor over the text it would select even though it was clearly created from images. Seems some software in the path (possibly my reader) was doing optical character recognition on the document. Most of it came through ok, but once in a while the slightly out of adjustment printer characters would be misread like a 9 for a 0, or a 0 for an O. Still, it saved a lot of time. Anyone else see scanned documents showing selectable text? -- Rick C |

Nice the way the download is packaged as a single ZIP file. The docs are in Chinese. I haven't tried Google translate on it yet. The new schematic is very difficult to read the text. I'm also having problems decoding the "forum description". It's readable imported into MS Word as Unicode-8. The photos of the PCB seem to be the old design, which lack the extra divider chips. This is going to be a challenge. >> take whatever you can get that produces enough drive to make the >> MB501L prescaler happy. >Yes, except it's meant to be (and mine are) and MB506. It also says MB506 on both the old and new schematics. <http://www.qsl.net/n9zia/900/mb506.pdf> That's odd because it's a divide by 128 or 256 that goes up to 1.6GHz. At 2400MHz, divide by 128 yields 18.75MHz. I originally thought that it would need to use all of the 60MHz counter frequency range, but now I'm not certain. The PIC used is apparently slow, and won't go that fast. 18.75MHz seems about right for the PIC16F628a where the data sheet says it quits at 20MHz. <http://ww1.microchip.com/downloads/en/devicedoc/40044f.pdf> The ForumDescription.txt file says that it's divide by 64 on the first page, but then claims that the low channel goes to 75MHz, and later claims that the prescaler is an MB501. Kinda looks like the ForumDescription.txt file is a mixture of the old and new designs. Looking at the new schematic, I see that one bipolar front end transistor was replaced by a dual gate mosfet. However, it doesn't look like the gates were tied together on the schematic. The original schematic is tiny, but after enlargement, I don't see a dot where the wires cross. Also, if you follow the signal path through the prescaler chip on both the old and new schematics, the higher frequency range input goes through the prescaler, into the DG MOSFET, and then to the PIC counter. If there is a sensitivity problem, it would only be on the lower frequency range input, which goes to the DG MOSFET directly. >Earlier schematics show two 4-bit counters before the PIC, >which by itself does not have a 60MHz counter. Probably correct, but I can't tell what those are. Also, I think you have it backwards. The older schematic shows no dividers, while the new schematic shows what I guess are dividers. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

It shows a sensitivity graph for the high frequency range with the following comment from Pg 12: It is noted that the UHF channel allows measurements up to about 450 MHz. This path comprises a divide by 64 stage claimed to be able to operate to 2.4GHz according to the published specifications. It is therefore surprising that the sensitivity fell as quickly as it did. Looking at the schematic and layout, my never humble opinion is that the designer didn't know anything about RF design and layout. The schematic shown on Pg 13 is quite different from either the old or new versions of the design that I previously mentioned. Instead of the extra divide by 4 packages, it has a 2nd DG MOSFET in front of the PIC counter. It also lists the prescaler as an MB506 which is divide by 128/256, not 64. It also shows that the gates of the DG MOSFET are NOT tied together. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
oldschool@tubes.com: May 28 03:44PM -0400 What is the difference between a BASS Guitar Amp and a STANDARD guitar amp, as far as the circuitry? I am assuming the speakers are made to better handle the bass frequencies, but are the circuits any different? I am asking this, because awhile back, I bought a generic Bass Guitar amp for a price I could not refuse. It's a small soild state amp, with about a 30W output.(or is ist 50W, websites seem to vary). Has an 8" speaker in it. I mainly bought it to be used to test other equipment in my shop. Anyhow, I'm impressed by it's sound quality. It does a fine job of reproducing both bass, and the high frequencies. It's only mono, but it has a nice clean sound and can get quite loud. It's just some off brand device, called "Gorilla". (model GB-30). (some worthless links do pop up on google). Made in 87. Over the years I have played around with many guitar amps, and repaired numerous tube amps, but this is the first "Bass Amp" I have touched. When I bought it, I actually thought I'd have to change some capacitors in order to get the high freqs, but this amp reproduces the highs as well as the bass. I have yet to find a schematic or manual for it, but it works, so I dont really need a schematic at the moment. (But I like to have one for everything I own). [If anyone sees one, pls let me know] Then again, I always thought that the "Fender Twin Reverb" amps had TWO reverb tanks. They dont! Just one..... "Twin" is just the name of those models, and there have been many variations in that model over the years, and it has always been a big seller with good reputation. https://en.wikipedia.org/wiki/Fender_Twin |

I think this was in the mid 1980's when CDROM drives had just been introduced. I installed a 1X or 2X CDROM drive (with a CD caddy) in her machine. I had left her office and made a stop at a local shopping center for an ice cream fix. My pager went off and I returned her call immediately, suspecting that I had done something wrong. She asked me "how do I extract the CD disc"? After some initial confusion, I determined that one of the standard procedures were going to work. It took me about 10 minutes to figure out the problem. She didn't understand the purpose of the CD caddy and had inserted the CD in the only available slot. No, it wasn't into the floppy disk drive, but into the space BETWEEN the 5.25" floppy drive and the new CDROM drive. I couldn't resist laughing, which turned out to be a huge mistake. I finished my ice cream, drove back to her office, disassembled the machine, and extracted the CDROM. I don't recall if I was still chuckling, but I probably was. She was very quiet and looked rather irate. The next day, I was informed by the bookkeeper that I should send them a closing invoice, and that it would best if I would not contact their office in the future. Oops. She apparently did not take kindly to my laughing, which suggested that I thought she was clueless. Lesson learned. I no longer laugh at my customers mistakes, lack of ability, failures to learn, stupid actions, lack of technical abilities, etc. More of the same: <http://members.cruzio.com/~jeffl/nooze/support.txt> -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

The situation caught me off guard and I wasn't prepared. I also assumed that she couldn't hear me laugh in the pay phone booth. I was wrong. At some point in the future, I ended up with an identical CDROM drive with the caddy thing. By that time, they were totally obsolete and nobody wanted them. I kept one on the shelf as a reminder to keep my big mouth shut. Incidentally, the original 1X CDROM drive cost me about $150 in 1985(?). The only data CD that we had available was something like "World Statistics" which cost about $100. Times and prices have changed somewhat. >blond joke, but normally, blonds have a sense of humor and can laugh at >things like this. So, I guess you just met a plain asshole with no >brains.... Nope. Like most small towns, Santa Cruz CA is ruled by a few families. She was the matriarch of one of those influential families. To them, I was a mere "tradesman", who should not be tolerated, and are considered disposable. I lost quite a bit of potential future business from well paying clients that day.
