RX-FEL
The RX-FEL is a RF protector and limiter for your radio receiver or SDR. Installed between the RX antenna and the receiver, it will limited any RF signal and will avoid to damage the receiver because strong signals.
The RX-FEL is a device that will protect the receiver front end from high level signals when operating in the proximity to other transmitters which could damage it. Situations such as multi op contesting, SO2R or Field Day.
- Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz)
- VSWR < 1.06:1 (reception)
-
TRX-FEL
The TRX-FEL (Transceiver Front End Limiter) is a RF protector and limiter for your radio transceiver. Installed between the antenna or amplifier and the transceiver, it requires to be connected the PTT signal from the radio. By default (reception) it will limited any RF signal and will avoid to damage the receiver in the proximity to other transmitters. When the PTT is activated by the radio, the Front End Limiter will be by-passed.
This model is highly recommended in multi operator contesting, SO2R or Field Day.
Specifications in RX (FrontEnd activated)
- Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz)
- VSWR < 1.06:1 Range 1.8-29Mhz
Specifications in TX or ByPass (FrontEnd disabled)
- Insertion lost better than 0.04dB in HF (1.8Mhz - 50Mhz)
- VSWR < 1.05:1 Range 1.8-29Mhz
- Max power 150W

6xBFP-FEL
The FEL is a PCB board where you can assemble the components to build a 6x receiver antenna switch, 6x bandpass filters from 10 to 160m and a limiter to protect the receiver.
It was designed by Imanol EC2DX, Jose Ramon EA7KW, Juanma EA5RS & Pablo EA4TX and since 2017 we are using this 6xBPF-FEL at out contest stations.

AS2x2
ANTENNA SWITCH 2x2
The antenna Switch AS2x2 is a 2 Input Ports into 2 Outputs Ports, usefull for a contest station where you have a Main Radio (RUN) and a Multiplier Station (Inband) at the same band. In this way, the RUN station uses the main antenna(s) while the Inband station is looking for new multipliers or QSOs and uses an RX antenna located far from the main antenna. As soon as the Inband station passes to TX, the switch AS2x2 inverts the antennas, passing the Inband station to use the Main antenna while the RUN does not run out of antenna put to use the antenna of RX.
The AS2x2 can be connected between the RUN Radio and the Linear Amplifier (in case a Amplifier is used) and between the Inband Radio and the RX antenna. As soon as the Inband Radio activates the PTT the AS2x2 will exchange the outputs, so the Inband will use the Linear Amplifier and the RX antenna will be assigned into the RUN Radio.
The AS2x2 can be used combined with the Interlock 5R so in this case, the Interlock 5R will control automatically the antenna switching.
