ACCESSORIES

A28 TUNING TOOL.

Rugged aluminum & brass tool with square tip for tall red and blue coils in our crystal controlled exciters and receivers. These slugs are relatively new, and you may not have a tool for them. $6.00      Note:  Some products use coils with a hex slot, and we do not presently have a tool to offer; however, standard hex tuning tools are appropriate.

A5 RCA PLUG.

Premium type plug with right angle cable clamp for termination of shields. Designed specifically for rf use with RG­174/u and similar cables. $2.00

A6 Coax Cable.

RG-174/u MIL grade coaxial cable.   This is the thin style cable used for short runs from pc board to rear panel of a cabinet and similar applications.  2 ft/$2.00 or 10ft/$5.00 

A7 Whip Antenna. 

Rubberized whip antenna, made for aircraft band, but useful for other vhf bands for receiving.  Size 20.5" long.  Can mount on any BNC style jack.  $10.00

A18 Feedthrough Filter.

Pi-section low-pass filter, combining feed through capacitor and ferrite bead in one package. Far better than plain feed through capacitor for decoupling rf from lines going in/out of rf tight boxes for repeaters, etc. 50dB minimum attenuation from 100-1000 MHz. With 8-32 nut and lock washer. $5.50

A40 115Vac-12Vdc Adapter.

Plugs into wall outlet and provides 12Vdc filtered (but not regulated) at up to 200 mA. These are suitable to power our receiver modules or any 12Vdc equipment which has on-board voltage regulator and requiring less than 200 mA current. Cable with pigtails can be soldered to a connector or directly to a module to be powered. (Ship wt. 1 lb.) $10.00

A95 Solid State Relay.

Relay to use with R122 Receiver, TD-2 DTMF Controller, and other applications.  Switches 115Vac up to 10Amp.  Input 5-24Vdc @7mA.  Requires heatsinking to switch over 5Amp continuously; so we provide some heatsink compound with it to use under base of relay to provide good heatsinking to a metal cabinet.   $29.50.

A96 Slug-tuned Coils.

5 each 2-1/2 turn and 6-1/2 turn coil as used in our kits. 
6-1/2 turn blue coil good for frequencies up to 100 MHz.  2-1/2 turn red coil good for frequencies up to 300 MHz. Stock up for future projects.  Also source of spare tuning slugs for other coils.  Use with A28 alignment tool.  Sorry, shields are not available.   ....$3.00
