ELAD ASW-2 is an automatic Rx/Tx switch that normally connect the antenna to RX output. When it senses RF power on RTX input (max. 100W), the antenna is connected to RTX input and the RX output (input of your receiver) is connected to ground to protect your receiver. Instead of using RF sense to switch antenna, a control line input lets your key/keyer or PTT line switch the antenna. Works on all modes : CW, AM, SSB, FM and digital modes. Individually tested up to VHF. Audio switch control is available for both the audio receiver and the audio transceiver. The ASW-2 is compatible with any receiver and any HF transceiver or HF transmitter.

  • Gas discharge protectionon on the ANTENNA connector.
  • DC–160MHz frequency range.
  • Power supply : 13.8VDC, 200mA.
  • Maximum RTX input power : 100W.
  • RF sense threshold : < 10mW (1.8MHz–30MHz tested).
  • Ontime : < 20ms. Release time : adjustable from 150ms to 3s.
  • Insertion loss : < 0.2dB @144MHz (0.15dB typical).
  • RX/TX and audio switch made with relays.
  • RX path isolated and grounded with additional relay during transmission to improve ANTENNA/RX isolation.
  • RX isolation : see RF Specifications and Typical Performance Characteristics in the User Manual.
  • Audio switch for CW operation allowing real time sidetone from transceiver (no SDR latency).
  • Audio switch made by pure contact allowing the use for other purposes (delayed PTT chain, aux PTT, bias injection).
  • Default ANTENNA-RTX connection when not powered to avoid transceiver damage.
