The CountyComm GP-5/SSB provides serious HF communications monitoring in a unique form factor and at a great price. The radio covers medium wave 520-1710 kHz shortwave 2300-30000 kHz and the FM band. Unlike most radios in this price category, the GP-5/SSB provides LSB and USB single sideband reception. It has a very unique Easy Tuning Mode (ETM). ETM does more the usual ATS. It scans all frequencies...
Bonito AntennaJet AAS300 Antenna splitter for 9kHz - 300MHz.
Bonito’s brand new active antenna signal splitter "AntennaJet AAS300" is splitting the signal from one antenna to 3 different receivers simultaneous. The AntennaJet has a wideband (>300MHz) and ultra low noise amplifier and can share one antenna up to 3 different receivers which can be tuned to fully different Frequencies, without...
Bonito AntennaJet ASM300 Antenna Switch and Mixer for 9kHz - 300MHz.
With the AntennaJet ASM 300, we add another component to our supplies of receiving equipment. It is USB-controlled and you can connect up to three different receiving antennas from 9 kHz - 300 MHz loss-free to one output socket.
Additionally, you can combine all three input channels according to your needs. They are then connected...
