It is undeniable that once a person reaches a certain stage in life there is a strong urge to recall the accomplishments of ones lifetime.  Martin L. Kaiser, Inc. has been around for 50 years and Marty Kaiser, a lot longer.  The format of this page is not set yet so let's see what happens.  Check in periodically for new additions.

The 3075 portable, battery operated, receiver system centered around a variety or receivers and transmitters.   One version was produced with a Regency multi channel crystal controlled receiver and included a matching, or several matching, crystal controlled transmitters.   Another 3075 system included a tunable Lafayette Radio MICRO-P50 or MICRO-P150 receiver and several transmitter such as the RT5, TT5 and BT50.  When Lafayette Radio discontinued the P50 and P150, I produced my own receivers known as the R-200PA/50 (shown in the picture) and R-200/150.  The right side of the metal sub chassis housed a variety of standard or long play cassette recorders.  The center console contained a mixer with provision for up to three microphones.  Switchable excitation voltage was available at each microphone jack to power external amplifiers and accessories.  There was also a 1/2 watt power amplifier and loudspeaker.   Six "C" cells powered the 3075 that was contained in a standard 3 1/2 inch American Tourister attache case. The 7079 did virtually anything that could be done with a microphone and/or recorder input/output.  Included were a two channel mixer that could mix any two of the six inputs, adjustable gain and selectable automatic gain control (AGC). Following the initial gain stages were an adjustable notch/peak filter and voice operated relay (VOR). The VOR had a short and long delay selector.   Outputs were available for a headset and tape recorder audio input and start/stop function." A 1/2 watt audio amplifier and speaker allowed general monitoring.  Six "D" cells powered the unit.  A standard 3 1/2 inch American Tourister carried the 7079 along with a selection of microphones, microphone preamplifiers and extension cables. The 7079X contains a 2049M electronic stethoscope with automatic gain control (AGC) combined with an adjustable notch/peak filter and 1/2 watt audio amplifier and loud speaker.  6 "D" cells powered the unit.  A standard 3 1/2 inch American Tourister housed the unit along with a large selection of microphones, microphone preamplifiers and extension cables This product was never fully accepted by the EOD/IEDD community... but at least I tried. The 7089 was an early attempt at a hostage negotiation system. It accepted two field telephone handsets or one complete telephone.  Included were a recorder audio output and on/off switch/VOR.  The handset, of course, did not requiring audio bypass circuitry but the telephone was modified for room monitoring.  Any combination of inputs could be selected. Six "D" cells powered the unit that was housed in a standard 5 1/2 inch American Tourister attache case.  The larger case provided sufficient room for the telephone headsets and telephone. Cable came in varying lengths and were wound on portable reels. The Mason A2 and A3, CEI RS-111 and Microtel countermeasure receivers were simply too expensive for most nonfederal customers. The 6060 was developed to provide a low priced alternative to these products. In spite of its simplicity it had some interesting features. A Sprague 610 Interference Locator was modified with a wide band I.F. to drive a Heathkit spectral display. The unit also included a sub-carrier demodulator. The most unique part was the 6060UHF high frequency down converter. It contained an adjustable 200 MHz comb generator and 5 GHz mixer that took the entire 5 GHz down to 200 MHz in 200 MHz chunks! The Texscan AL51 proved to be a ready replacement for the 6060. Some modifications were made in the hopes some potential customers would buy it from me. Its nomenclature was the 6060C. I supplied it with the antennas from the Sprague 610 and a 1079 audio power amplifier. The Texscan analyzer was later replaced by the Avcon PSA65C. In the early 70s I was asked by a State Police agency to produce my first hostage phone, the 7080. It used rotary dial telephones because at that time dial telephones would work both on dial and tone lines but touch-tone telephones would not work on dial lines. It came with a bunch of wire, connectors and clips to meet virtually every situation. The 7080 has been battle tested at many prison riot and hostage situations. The latest version still looks the same but it contains up-to-date technology. During the "hay days" of my business, people were bugging (pun) the heck out of me for a simple telephone line test. The LTS-4 answered most of their concerns. It measure line voltage and loop current and line audio. Didn't sell that many but it worked and looked neat. Talk about an old timer. This Lafayette hybrid (tubes and transistors) receiver filled the temporary gap between fully tube and fully transistor receivers. It had very good sensitivity and a wide-band I.F. Shown with it are the BT50 body transmitter (50mW), RT5 room transmitter (5mW) and TT5 telephone transmitter (5mW). During the "hay days" of the business I produced thousands of the little units. They were self-excited (no crystal) but stayed close to their 42MHz frequency once installed. The intelligence community did everything in its power to keep me from manufacturing and selling a nonlinear junction detector. Shown is the 4059 that operated in the 250 MHz to 410 MHz range. I built several different models... the 4049U, the 4059H and the 4059V. All three were designed to find the semiconductors in the suspect device. I also produced the 4059L which was unique in that it didn't find the microphone but the signal propegated down the wire until it found the input trasmitter of the audio amplifier. .  Eventually I brought in a British NLJD manufactured by CSD (they went belly up) named the DIVINER (FCC ID# IJCDIVINER). It has excellent sensitivity and worked very well. As with my units, I was totally unsuccessful with attempts to market my products. Shown here are the RR40CN pocket receiver and a 100mW, 500mW and 1W companion transmitter. The receiver pushed the state-of-the-art limits on sensitivity... better than .05uV. Its I.F. band width was 2Khz and in those days, the lower the better. They were fully transistorized but current hogs. The SCAN23 had its place in time. During the U.S. Capitol grounds riots of the early 70s hand held Citizen Band (CB) transceivers were the communicators of choice for the so called "left." There were so many radios on the air at one time that all 23 of the CB frequencies were usually occupied.  The Capitol Police came to me and asked if I could build a device that would indicate transmitter operation on all frequencies all at once. Scanners were out of the question. Thus, the SCAN23 was born. It simultaneously indicated all frequency usage instantly. The unit contained a broadband receiver covering all channels and individual filters which, when activated, would turn on a light for that channel. The police could then watch the light panel and a "leftist" to see which light came on when he or she lifted their transceiver to talk. That channel could then be monitored and "neutralized." A portable CB transceiver was included in the package should the Capitol Police wish to do just that. The UUA-1 (Utility Audio Amplifier-1) came out of the Intelligence Material Development and Supply Office (IMDSO) at Fort Holabird, Maryland. During the mid 60s it was the state of the art... albeit relatively crude. It contained a few transistors and transformers. I probably produced a few hundred. Then came its replacement, my 1059. Once my 1059 caught on, it was good-bye UAA-1.

Developed New Missile Beam Area Man In Strategic Role Two new United States defense systems which can detect, intercept and destroy enemy missiles far out in space, have been revealed by President Johnson.  One of the systems, a radar-like beam, which bends around the earth's surface, and upon which the new missile-destroying system depends, was developed under the direction of a 29-year-old Pennington man, Martin Kaiser, of 418 Hale Street. The President said: "We now have developed and tested two systems with the ability to intercept and destroy armed satellites circling the earth in space. I can tell you today that these systems are in place, they are operationally ready and they are on the alert to protect this nation and the free world. Kaiser said he worked for Radio Corporation of America Laboratories in Dutch Neck when, in 1962, an RCA engineer discovered the principle of the bending beam.  Kaiser was appointed field manager and engineer for the project, known as CAMEBRIDGE, at an RCA Lab in Burlington, Mass. After three months, at the end of 1962, all equipment was taken to Barbados, West Indies, and Kaiser managed the work until June, 1963. The young scientist hails from Wilkes Barre, Pa. He is presently at Rider College, studying for a degree in management, which he hopes to attain in June, 1965. Johnson revealed the new "over-the-horizon and thus detect hostile missile launches within seconds. "This means more time to prepare for our retaliatory strike and more time to decide - prudence and reason - the scope of our retaliatory strike" he said.
