R100 VHF FM Receiver
A premium quality receiver for demanding applications
| Our 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! Note: Our synthesized R301 Receiver has advantages for 2 meters or 220MHz bands. The frequency is set by dip switch and there is no need to wait for a crystal or pay for a crystal oven.

See what our customers say about these modules:The 440 and 220 transmitter and receiver boards we purchased from you years ago are still in operation today and have been working at 100% the whole time. They are totally reliable and even working under some harsh weather conditions. The crystal heaters we installed in one location on the receiver boards keeps the frequency rock solid. The downtown repeater site has two UHF receivers, one 220 receiver, the main 220 transmitter exciter board plus 10 watt amp - and they all perform flawlessly all the time. Even after years of use to this day, they have never stopped working or drifted off frequency. We are also using ID boards, timers boards and so forth on two remote receiver sites - and they are all as accurate as the day we installed them over ten years ago. Good engineering designs - good going! Thanks. ... Tom Mogan, AA6IP; Sacramento, CA |
