What is the difference between the SDRSwitch and the RXin/RXout Switch offered by SDRSwitch.com?
The SDRSwitch was designed for those who want the minimum insertion losses and already know that their SDR RX will be their receiver of choice for their station. Someone who knows that an SDR RX along with SDR Console is far more than a pretty panadapter.
The RXin/RXout switch allows you the option of receiving on both your transmitting radio as well as your SDR receiver. This does however come at a cost. The insertion of a 2 way splitter will add a minimum of a 3dB loss to your receive signal. Obviously 3dB is a huge loss of signal and why most serious operators do not decide to go with the dual RX. That said, on VHF, this can be negated by installing an LNA in line which not only sets your initial noise floor but will give you so much gain that the 3dB will not be missed.
SDRSwitch.com provide both the SDRSwitch and the RXin/RXout switch in two frequency ranges. The 0-70MHz products are aimed at those who want low losses on HF, 6M and 4M but do not require the superior relays and figures provided by the 0-450MHz products. You can compare the S21 figures on the individual product pages to decide which you feel will be most useful in your shack.
