Below are are manuals for equipment from other manufacturers that don't have their own pages at this site. When we have enough from one manufacturer we will create a page for them... like the manuals from AEA, Alinco, Bird, Cushman, Helper, Instrument Flight Research (IFR), Ritron, Radio Shack Tektronix, and Zetron which used to be here but are now on their own pages. Test equipment companies are listed under "Test Equipment" on the main index page.

Donations of manual files for this page are gratefully accepted.

Advanced Receiver Research (ARR) Preamp Instrcution Sheet 446 KB PDF
This covers the P28VDG, P50VDG, P136VDG, P144VDG, P220VDG and P432VDG models.

There doesn't seem to be any one place where all the Azden amateur radio manuals are kept. If anyone has a large collection and wants to contribute them I'll create an Azdan page at this web site. Until then you will just have to do a Google search for whaever you need. A while back I had to find a PCS-5000 manual, so here it is: Azden PCS5000 Instruction Manual 5.09 MB PDF

Cetec-Vega Model 188 tunable PL encoder (includes schematic) 54 KB PDF Courtesy of WA6ILQ
While most modern tone encoders have a DIP switch to select specific tones this one has a 15-turn trimpot (or 20, depending on the production run), and the circuit is easily duplicated on a perfboard. Cetec-Vega no longer makes it (in fact, Cetec-Vega is no more), so build one and have fun!

Channel Master five-band monitor antenna, model 5094A Monitenna Manual 45 kB PDF courtesy of A. Nony Mous

Charge Guard CG-12D Instructions 210 KB PDF courtesy of Mike WA6ILQ
This is a handy box that you wire between your car battery and your mobile radio(s) or other equipment (MDTs, scanners, laptop chargers, etc) to help prevent dead batteries or equipment damage from out-of-range voltages.
The CG-12D draws 15 milliamps idle, and can switch 30 amps. The unit's voltage source is directly from the car battery and the switched output drives the radio(s) and other equipment directly. It is wired to the ignition switch and when that lead goes high it turns the equipment on, and when it goes low (i.e. you turn off the ignition) it starts a timer. When that time period expires it will automatically turn off the DC power. The time duration is programmable for 15 minutes, and then in steps from 1 to 15 hours. The box also has two voltage detectors to protect the load, the first shuts the radio off if the battery voltage drops below a threshold (default voltage is 11 volts). The second is a high voltage detector that shuts off the radio(s) if the voltage rises above a threshold (default is 18 volts).
The CG-12 is an older model that is discontinued but frequently shows up on ebay and are worth considering for any mobile installation. Search for Charge Guard" or for "ChargeGuard".
The company is a division of Havis, Inc. and can be found at http://chargeguard.havis.com.

Clegg Communications Corporation was run by Ed Clegg, W8LOY, from the 1960s until he died in September of 2001 at age 80. Clegg was one of the early and most popular amateur VHF radio manufacturers and importers. His designs included the Zeus transmitter and companion Interceptor receiver, the Clegg 99er 6-meter rig and the AV-144 All Bander receiving converter. There were actually two versions of the AV-144 allbander, one a small stand alone box and the other was contained in the speaker cabinet for the Interceptor receiver. The last American made radios that Ed produced were the FM-21 (his first 220 radio), a crystal controlled mobile that used one crystal per channel with a mixing scheme similar to what Motorola did much later with the MODAR Triton marine radio which evolved into the Metrum II amateur radio. Eds last 2m design was the FM-DX, a 45 watt synthesized radio in the days when most other 2 meter ham gear was 10 or 25 watts.
It was never clear if the Mark 3, FM-27 and FM-28 were designed by Ed, by the Midland staff engineers, or by Unidens staff engineers but the units were made by Uniden and imported under both the Clegg and Midland names.
One trait of the imported radios he sold is that Ed never shipped a unit in a factory sealed carton, and he was proud of that. Each and every boxed radio was opened, tested and resealed prior to shipment and the test data was included with each individual unit. This was because they were made by Uniden and imported by Midland under an OEM agreement, and Ed believed in 100% Quality Control. He was NOT going to sell something under his name that didn't meet specs.
The FM-76 (Midland 13-509) was also sold by B&K, the test equipment people, as a Cobra 200, the only piece of ham gear that they every marketed.
The FM-28 (the same as the Midland 13-510) was sold as the Uniden 2080 in Japan and possibly in the UK as well.
The FM-88 was actually the same as the Midland 13-510A, and is capable of operating from 143.000-148.995 to take in MARS and CAP frequencies where the FM-28 / 13-510 was limited to 144.000-147.995 MHz.
Mark Three 1.2 MB PDF. Equivalent to the Midland 13-500. The last page of the PDF is a full-size schematic diagram.
FM-76 1.5 MB PDF. Equivalent to the Midland 13-509. The second page of the PDF is a full-size schematic diagram.
FM-88 1 MB PDF. Equivalent to the Midland 13-510A (the 2m version of the Midland 13-513 220 radio).
Ed never marketed the synthesized 220 radios.
The FM-28 and FM-88 had a factory installed scanner option (FM-28S or FM-88S) that was very rare. The scanner was actually made by CES as their 800-ML product.

CSI - There are or were three different companies that used the initials CSI - one was Communications Systems Incorporated (CSI) Company in Lynwood, Washington which is long out of business. That CSI was a manufacturer of commercial two-way radio PL/CG/tone/CTCSS/DPL/Digital-sub-tone panels (community repeater/shared repeater tone panels) . These blue-gray color CSI-32 plain and CSI Super-32 Repeater Tone Panels are not to be confused with similar products made by Connect Systems Inc. originally in Torrance (now in Ventura) in Southern California - the two companies despite the identical monikers are not and were not related in any way. Nor are they related to a third "CSI", Communications Specialists Inc. (also known as Com-Spec), the makers of the popular subaudible tone encoders and decoders, which is in the city of Orange, in Southern California. Communications Specialists Inc. (Com-Spec) and Connect Systems have their own pages at this web site.

The first file listed below contains the basic (standard) CSI 32 Repeater Tone Panel Controller manual (photo of the unit). The second file contains the CSI Super 32 Repeater Tone Panel(Controller) manual. The last two files contain the two pages of programming commands from the basic (standard) CSI 32 Tone Panel Controller Manual; the zip file contains two GIF files, and the pdf is a two page image file.
If anyone has photos of the Super 32 panel we'd appreciate an email...

They wrote:
We did go by the name Data Signal quite a few years ago. We got out of that business when cell phones took off and eliminated about 80 % of our product line. Fortunately, we do still have some of the old product manuals available. As an example, we have a CWID 70-DC version that you can purchase for $10.00. It has all the information that you need. Schematics, theory, installation and so on. One thing you do need to know is that coding of the PROM is no longer possible by us. If you need to change the code, then you will have to go elsewhere.

Grundig Yacht Boy 400PE 842 KB PDF Donated by A. Nony Mous
This is a really nice little portable short wave receiver. I used to keep one in my repeater site toolbox in a Seagrams Crown Royal blue cloth bag inside a canvas bag. It was my hilltop entertainment while I worked on the repeater equipment. It's amazing how well it receives when the antenna is a tower guy wire... (our HF remote used two of the four tower guy wires as an inverted V antenna). BTW, the external power input is 9vDC, tip positive.

HAL ID-1A Diode Matrix Programming 670 KB PDF donated by Greg Beat W9GB
This is not the complete ID-1A manual, just the chapter on programming the diode matrix. Note that the original 1N270 germanium diodes are hard to find, since they are no longer actively manufactured. The Central Semiconductor CDSH270 is a Silicon Schottky diode specifically designed to replace Germanium diodes manufactured with 1950s technology like the 1N270, 1N277, etc. with 1990s technology. Advantages of this new technology are lower forward voltage, lower leakage, faster switching speed, and a more robust package. Mouser part # 610-CDSH270 was a reliable source for this diode in 2008 at about 25 cents each. The HAL ID-1000 uses a DIFFERENT Diode Matrix format, so this manual excerpt is not helpful for that newer CW ID model.

Waters Hybrid Couplers model 3001 and 3002 563 KB PDF courtesy of A. Nony Mous
The Waters phone patches were the Rolls Royce grade units of the 1960s-1970s and are still prized today. The 3002 had an additional audio leveling amplifier that worked quite well. The physical design was interesting as well - the unit could sit horizontally on top of a radio, or vertically next to it. The front panel was reversible for either mode.

The 3002 had an additional audio leveling amplifier that worked quite well. The physical design was interesting as well - the unit could sit horizontally on top of a radio, or vertically next to it. The front panel was reversible for either mode.
