March's transmitter hunt will be on the 12th and starts at our new North Starting point, 101 Cheyenne at 2pm, mileages will be taken at 1:30pm. Assistance is on any HARC network repeater….like H2 (Apex) repeater 449.925 (-) pl 131.8Hz .
SA-818 Carrier Boards
SA818CB-DL
The SA818CB-DLVer2 carrier board makes using the NiceRF.com SA-818 walkie-talkie radio module easy to incorporate into your project builds adding two-way radio capabilities.
The SA818CB-DLVer2 VHF or UHF radio modules function with an on-board 47-53 ohm resistor dummy load.
The SA818CB-UHF Ver 3 boards are for use with UHF radio modules employing an external antenna.
SMD/SMT Low-pass filters are pre-installed on Rev3 and higher boards.
Using a low pass filter installed on the board reduces the (F2) 900MHz spurious emissions to approximately -60 db from the operating 440MHz frequency.
Assembly instructions, schematics, photos, mounting hardware, all components supplied for model ordered.
DUTY CYCLE: The SA-818 can be used in a high duty cycle environment in the low-power mode only.
Adequate cooling and intermittent transmit key down must be observed for operation of the SA-818 module in the 1 watt setting without damage to the device.
** High duty cycle use, such as connected to a repeater Allstar node, has shown failures because of the extended duty cycles and the need for adequate cooling.
SA818CB-DL Ver 2K Kit $20.00 plus shipping (Does not include SA-818)
SA818CB-UHF Ver 3K Kit $25.00 plus shipping (Does not include SA-818)
SA818CB-UHF Ver 3 $45.00 plus shipping (Includes SA-818, programmed, assembled, tested and 24 hour burn-in)
Shipping & handling to the lower 48 states is $7.00, any other locations will be calculated and verified prior to shipping.
SA818CB-UHF Ver4 boards may be shipped on orders for SA818CB-UHF Ver 3. depending on Ver 3 stock.
Electrically Ver.4 boards are the same as Ver.3, the difference is an updated low-pass filter on the transmitter output.
