Thanks to Richard Hagen LUNAR now has a 100 channel Rocket Hunter radio locater receiver and a directional antenna. This unit will greatly improve your chances of finding a lost rocket, assuming, of course, that you have installed a compatible radio transmitter. The unit we now have is a Rocket Hunter RHR-100. The unit is in the LUNAR trailer and you will need a fresh 9V battery to make it work (we don't store the unit with a bettery installed.)
This unit receives a signal from any transmitter in the 219 Mhz band. To use this receiver, you must obtain and mount a transmitter in your rocket. Transmitters are no longer available from Rocket Hunter and Communication Specialists Inc. as they are both out of business. Transmitters are available from marshallradio.com in several variations. They range in price from $200.00 to $450.00 and are available in a couple of different sizes. These are falconry radios but should work with our receiver.
When you buy a transmitter, be sure to choose a 219Mhz model to work with our receiver then choose an available channel (see below). Anyone purshasing a transmitter should let the webmaster know so it can be added to the table below. The frequency will be clearly marked on the transmitter (219.XYZ). To use the receiver with your transmitter, set the receiver to the same frequency as your transmitter. On the reciever, the X value is set with the first thumb switch, the Y value with the second and the Z value with the TUNE knob.
