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. 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 Instruction Sheet   446 kB PDF file
This covers the P28VDG, P50VDG, P136VDG, P144VDG, P220VDG and P432VDG models.
Azden PCS-5000 Instruction Manual   6.7 MB PDF file
Azden PCS-7000H Schematic Diagram   3.6 MB PDF file
All of the 7000-series radios have nearly the same schematic. Obviously the TX and RX sections would have different component values. Supposedly the manuals had addendums to cover the various band differences.
John Bell Corp. AP4800 Manual   387 kB PDF file           Photo of the AP4800 board
B and D Enterprises 1P repeater controller manual   163 kB PDF file courtesy of KB3CEZ
CBS Labs Audimax III and IIIS automatic level control   920 kB PDF file Compliments of Larry Saletzki WA9VRH
CBS Labs Volumax model 400 automatic peak controller   349 kB PDF file Compliments of Larry Saletzki WA9VRH
Cetec-Vega Model 188 tunable PL encoder (includes schematic)   54 kB PDF file Courtesy of Mike 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 file
ChargeGuard CG-12D Instructions   210 kB PDF file courtesy of Mike WA6ILQ
ChargeGuard CG-X Instructions   387 kB PDF file   current model.
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.
Mark Three   1.2 MB PDF file   Equivalent to the Midland 13-500. The last page of the PDF is a full-size schematic diagram.
FM-76   1.5 MB PDF file   Equivalent to the Midland 13-509. The second page of the PDF is a full-size schematic diagram.
FM-88   1 MB PDF file   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.
CPI Communications Model 824 Autopatch manual   530 kB PDF file donated by Jay Damkoehler W4EBO
CSC CWID-50B, -50BR, and -51B CW ID units   456 kB PDF file donated by Eric Lemmon WB6FLY
Note that the original 16-pin TTL EPROM is no longer available, but you can make an adapter to allow use of the more readily available 27Cxxx series EPROMS. The manual walks you through what each bit is used for.
CSI - There are or were three different companies that used the initials CSI - one was Communication 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...

The first four of the Communication Systems Incorporated (CSI-Lynwood) files below were donated by Skipp May

Data Signal Inc. (DSI) became Game Country, Inc. and they still have some old manuals left.
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. To get the manual send a check along with your complete mailing address. Please let me know if you need further assistance.

The Drake TR-33C 2-meter portable transceiver   3.5 MB PDF file donated by Mike WA6ILQ
This is a single-crystal-per-channel design similar to that of the Motorola Metrum or MICOR. Note that the unit has a mess of of small coax stuffed into the bottom of the antenna pocket. It's a magic length - a quarter wave at 2m - so don't change it.
Emergency Beacon Corporation EBC-144 Jr. manual   879 kB PDF file
Bob WA1MIK scanned his own manual and cleaned it up significantly. It's still full of errors, but so were the radios.
HAL ID-1A Diode Matrix Programming   670 kB PDF file 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 file
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.
