Last Update May 26, 2008 |
From time to time we will announce and run special limited time promotions, list items that were built or purchased by us to be tested out on ATV, production samples, previous models, prototypes, over runs, surplus, etc.
Mary Ann gave me orders to stop being such a pack rat because it takes too long trying to find anything digging through piles of stuff - So please check back often.All prices include UPS surface shipping in the contiguous USA if the order totals $99 or more. for Specials or go direct to: Power Modules, Semiconductors and Parts, Crystals 
LB1000 Mini Color Camera with Mic......$79 Price Reduced by $20 Comes with lens you can set from 1" to infinity and regulated 12V wall plug power supply, but it can run for over 6 hours on one 9V alkaline battery. Make your own DC power cable with a 2.1 x 5.5 DC power plug - Radio Shack 274-1569 - to connect to a battery or other supply.
Pre-emphasis in the FM ATV transmitter along with corresponding de-emphasis in the receiver can more than double the distance or add a P unit for the same distance (6 dB) by lowering the noise floor in the receiver. Pre-emphasis and De-emphasis is standard in the USA for 1200 MHz FM ATV systems - CCIR 405-1. However, most board level imported FM ATV transmitters and receivers do not have this feature.
PEK Tx Pre-emphasis kit...$15 
GVM-1 Gunnplexer Video Modulator Board....$29
This is a board that has many other uses:
Gunnplexers make a great little microwave (10.4 gHz) ATV link or way to demo ATV and how directional antennas work, bouncing off metal objects, multipath, etc., in a more interesting visual way at ham clubs or ham class rooms. • • The boards are $29 if ordered individually, but for ham club or group projects, you can have them for $25 each if you buy 2 or more. 25 left. 
PA5 board..........$25 
TXTVb ATV Exciter/Modulator Board...$29 Make a low cost 70cm ATV RF Test Generator for tuning up receivers or antennas. Demonstrate ATV at a ham club, Scout Jamboree, Field Day, etc., with this unit - transmit in the building to a cable ready TV set. This board puts out about 10 mW and uses the same crystals as found in all our 420-450 MHz ATV transmitters - standard 70cm frequencies available from us. The board comes partially built (as shown in the photo) and with all 12 of the additional parts as a kit to complete the board. Assembly and tune up instructions using a DC Voltmeter are included - download and see the data sheet by clicking on the board photo above. Or, by using a different crystal and additional parts kit, you can drive a 2 meter in / higher band out Transverter like those available from Downeast Microwave, SSB and others, you can add the AM ATV mode with this board. The boards are stuffed and soldered with the exception of the inductors, parallel capacitors and 3 2N5770 transistors which we will include as a kit (specify 2 M or 70cm) with each board for use on 70cm with 10 mW or 2 meters to drive a transverter with 50-100 mW. 70cm crystals are $25 and use the same ones as found in all our transmitters. We have a limited supply of crystals for ATV on 1265.0 (1268 MHz Transverter) or 1289.25 MHz (1296 MHz Transverter) at $5, or you supply the crystal (order from ICM catalog #473370 - 2 meter F/2 and HC-50 holder) for the frequency you want to end up with after mixed in your Transverter. We made a bunch of these in 1995 for use in our TVX series of export TV transmitters for channels 3 to 13. But not much later Amprex and Philips stopped making the companion 10 watt power modules and no similar power modules are available - that ended that product line. Size is 4x2.25" - will fit in a Hammond 1590C or D die cast aluminum box - and takes 8 to 14Vdc at 40 mA. Use the FMA5-G for sound. TX33-1b 913.25 MHz 1W AM ATV Transmitter... $180 
This transmitter was used in our milk crate ATV repeater for public service work. But due to local interferance from other services, we switched our system over to the 23cm band. So this transmitter is available. It gave good video and audio over a 6 mile path between aid stations at a trail race and using half (3 ft boom) of a Directive Systems 3318LYARM Loop Yagi at both ends line of sight. Power Modules 
Click on part numbers for data sheet.200 mw max RF input, run on 13.8 Vdc Bandwidths are actually wider than listed.
25 mW in 18W out 68-88 MHz. Used in our TVX ch3-6 export TV transmitters includes TC PA bare board. Parts We have an excess of through hole parts that were purchased in large quantities before we started using surface mount parts: 
2N5770 small signal TO-92 NPN RF Transistor used in our crystal controlled transmitters and downconverters for the oscillator and multiplier stages. Up to 50 mw at 400 MHz.
Motorola MRF901 low noise UHF preamp transistor.............$5 ea., 23 in stock. 
Philips BLU98 RF transistor used in our TVG test generators, TXA5-33 and TXA5-23 transmitter multiplier stages. Capable of up to1/4 watt output on 23cm. Similar to Motorola MRF581. $2 ea - 100 in stock. 
2N/PN2907A small signal TO-92 PNP transistor. Used in our sync separator circuits and other products. Great general purpose PNP. 
IC's - DIP integrated circuits. 
2-8 pF ceramic trimmer cap - Sprague GKU6R000. Capacitors - disc ceramics, electolytics, etc. 
Inductor / RF choke, .25 each or $20 per 100 
Resistors - leaded 1/4 watt carbon film, bags of 100 or 200 ....$1/100 
Trim Pots - Thumbwheel carbon trim pots, Piher type PT15YB 
Crystals $5 ea: we have a variety of HC-25 plug in crystals used in our downconverters 
Bias-T Parts Kit............$15
Power your Antenna mounted preamp on the 400, 900 or 1200 MHz band through the coax with this bias T. Great for powering Downeast 23LNAWPQ or 33LNAWPQ antenna mounted preamp from the ham shack. Insertion loss was measured at less than 1 dB. Kit contains LMB cad plated - solderable - metal box with lid, 2 BNC chassis jacks, feedthru cap, 100 Ohm 1/4W resistor,.22 uH inductor and data sheet. |

You can easily add on by placing the transmitter PEK kit in the camera video line and receiver DEK kit in the video output line, and readjusting the video gain pots. See our
