224.560 Repeater

This is Not done Yet

Tower Job We Did On Saturday 08-25-2007 And Picture's

I Have Always Wanted To Put A 220 Mhz Repeater On The Air For A Long Time And I Have Always Told Everyone That When I Do Put One On The Air That It Was Going To Be Very High Profile System

Many Years Ago I Started To Put One Together But I Did Not Have The Time To Do It With Working 2 Jobs And Now I Have To Much Time On My Hands And Here Is What I Have come Up With

The Repeater Is On 224.560 With A Minus Offset With A Pl Of 186.2

I Am Going To Put Up 2 More Receivers Up For This System And I Am Going For The Time Going To Us 3 Difrent PL s For This Until I get Another Voter Then Things Will Change

I Have Built Up A Hamtronics Transmiter And Its Putting out 2 Watts Of Power

The Exciter Is available for various vhf bands, and the TA451 uhf Exciter are tough, commercial-grade, low power transmitters which answer the need for the most demanding applications. They can be used as stand-alone units or as drivers for our class-C power amplifiers. They are ideal for voice operation in repeaters and voice links. Used with our data modulators, they make handy links for computer-controlled equipment and reliable telemetry links in place of expensive phone lines. Over the years, our commercial customers have told us amazing stories of all the applications in which our exciters and receivers have performed in the most demanding environments! Uses such as flying drone airplanes for the military, telemetry in rockets, audio & tv links for security systems, controlling city water supplies, research on wildlife migration, listening to whale sounds, doing remote broadcasts of sporting events, and reporting on traffic conditions from helicopters. Some of our enterprising oem customers have purchased our units to save their customers trouble and money by combining our transmitters and receivers with digital equipment they make. This equipment then was used for security systems, monitoring freezing temperatures in orchards, checking milk production in dairy herds, reducing manpower required for traffic signaling in highway construction, detecting leaks in water mains. The list goes on and on. You can rely on our transmitter and receiver modules for your project, too! If you have any questions, give our engineering department a call. We'll be glad to work with you and suggest cost effective solutions.

I Have Built Up A Hamtronics Receiver

R100 vhf receiver is our traditional crystal controlled receiver. It was designed for demanding applications, such as repeaters, audio and data links, packet radio, and remote control. The R100 has a positive-acting, wide-range squelch circuit and additional output terminals for low-level squelched audio and discriminator audio as well as COS. And it is now easier to assemble and align. The R100 retains all of the popular features Hamtronics® receivers have been noted for. It uses triple-tuned circuits in the front end and excellent crystal and ceramic filters in the i-f with steep skirts for close channel spacing or repeater operation. The i-f selectivity, for instance, is down over 100dB at ±12 kHz away from the carrier, which is 4050 dB better than most transceivers. Low noise fet's in the front end provide good overload resistance and 0.2µV sensitivity. You won't need a preamp with this receiver! Able to hear weak signals, resistant to intermod, desense, and adjacent channel interference, easy to interface. Isn't that what you need for your demanding applications? Whether you select a kit or a factory wired and tested model, you will be glad you did!

SECURICOR 220 MHZ AMPLIFIER

220 – 224 MHz Linear Amplifiers And Matching 110 VAC Power Supply Manufactured In 1999 The Power Supply Is 28 Volts For The Amplifier For 160 Watts Out Put

The amplifier is approximate 7” high x 6” wide x 9” deep box designed to slide into a larger rack housing the power supply and other equipment. It has a large heat sink, internal fan and two front panel LED’s – red for power on/off and lights when the power supply is turned on and green for transmit/receive and lights when +5 VDC is externally applied to activate the bias circuit and turn the amplifier on. Rear panel jacks are “SK1”, a SMA output (no connection required) which appears to be low level feedback or ALC to the system transmitter, “SK2 PA Drive” is the SMA amplifier drive input and“SK3 TX OUT” is the “N” amplifier output. The “D” type 9 pin connector, “SK4 PA CONNS” requires + 5 VDC applied to the second pin from the top of the left side 4 pin row (or to the stripped yellow wire of the pig tail on the supplied matching plug) to turn on the bias and amplifier to transmit and light the front panel green LED. None of the other 8 pins on this jack require connection to use the amplifier nor are any “ground” for the +5VDC which must be connect elsewhere (or use the shield on the supplied connector pig tail). The bottom “PL1 DC POWER IN” jack provides the required + 28 VDC and +14 VDC through the supplied matching power cable from the jack marked “SK2” on the power supply. The 110 VAC switching power supply is contained in an approximate 7” high x 3 1/2” wide x 13” deep box with front panel on/off switch, red on/off LED indicator, and internal fan. The rear panel has 4 output jacks marked “SK1”, “SK2”, “SK3, and “SK4”. The amplifier power cable connects to jack “SK2”with the three other jacks supply 14 & 28VDC to other system units and can be used with the included matching cable to power whatever you have that requires 14 or 28 VDC. The power supply housing contain three separate “floating” Lambda supplies, one 24 – 27 VDC @ 17 amps and two paralleled 12 – 15 VDC @ 2 amps each. The PL1-4 & SK2 pin connections are as follows: Pin 1 (Blue wire) – ground, Pin 2 (Green wire) - +14 VDC, & Pin 3 - +27 VDC. Amplifier Input/Output Power Input to the 2N3866 first stage should probably be limited to 20 dBm This was tested at 500mW input with 160W output!

I Have Alot Of Time In This Amp To Get It Working . Its Been Running Full Time For 11 Months Now And Today Is 09-10-07
