Technical Information and Modifications for
Other Manufacturer's Equipment
Compiled by Mike Morris WA6ILQ
Maintained by Robert Meister WA1MIK
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|
|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|

|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|
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 http://www.radiowrench.com.

Here's the corrected chapter 4, programming information that has both sides of the page scanned. 6.4 MB PDF file.
|CSI 32 / Super 32 command list One 511 kB ZIP file containing two GIF files|
|CSI 32 / Super 32 command list (a two-page PDF file) 570 kB PDF file|
Data Signal Inc. (DSI) became Game Country, Inc. and they still have some old manuals left.
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.

Wansen S-350-5 Switching Power Supply Load
Test 35 kB PDF file by Eric Lemmon WB6FLY
This generic, inexpensive 350 watt, 5 Volt, 70 Amp unit is marketed as an LED lighting power supply. It was purchased by Bob WA1MIK who sent it to Eric WB6FLY for load testing. Read his Megawatt S-350-12 article above as this supply is nearly identical inside and out.
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.
