SDR Transceiver and Receiver Switch Antenna Sharer TR Switch Box with Gas Discharge Protection 160MHz
Questions and Answers
The details sections says 100W output, but that's not possible with a power supply of 13.8V/200mA. Can anyone shed light on this?
It is 100W THROUGHPUT. 100W from transceiver out into the adapter and same 100W out to the antenna. Power supply (12V 200mA) only for internal circuitry (relay, switch, whatever is inside) 100W means you can not use with linear amplifier (500W-1kW)
The Specification is DC-160mhz. My unit will NOT perform above 50mhz -VERY high SWR.?

arrived on time and worked well. The only thing would be a schematic diagram should be enclosed.

Very good product. Works properly. Very good finish. Took a while, but arrived correctly. Packaging could be better. Product could be better packaged.

I Ordered 2 of them one directly from China and the other in the USA, I would like to say that the China Package arrived very well and is working properly, now the Packaged shipped from California arrived all crushed box and hole in box as well., I have not tried it out yet, but they need to pack better.

Seems solidly built. Bought it to create a panadapter with my Icom 718, Raspberry Pi and RTL-SDR. I give it 5 stars. it's nothing fancy but works as intended, so what more can you ask for.

arrived in about a week I moved the internal jumper to share the antenna. The device works perfectly. Sharing my DX Commander antenna with my Icom 706 transceiver and my SDRplay2. Now I have a waterfall display while using my old 706. Recommend this SDR Switch.

Excellent bit of kit that really compliments a radio/SDR combination to act as a pan adapter. Wiring PTT switch is recommended so it doesn't repeatedly switch when using SSB/CW. So far tested with 10W without issue. No notable affect on SWR on HF bands I tested. Inside is a jumper to toggle whether transceiver should receive at same time as SDR. I have use case for both jumper configurations (assuming it'll improve signal to SDR when TRX disconnected...but haven't noticed significant SNR difference), so drilled 12mm hole in front panel and fitted a 12mm latching switch to jumper with Dupont connectors. There is plenty of space inside the case and front panel for this. When powered off, defaults to safe configuration, grounding SDR and connecting transceiver to antenna: useful in case unit unexpectedly lost power. Really happy with this purchase. Arrived quickly. Recommend for HF rigs.

it's working very well with Yaesu FTDX10 and RTLSDR v3.

well made SDR Switch, very good value compared to the MFJ alternative. Recommended.

This is a very good panadapter switch so you can use your HF antenna (or upto 160Mhz) with your radio and your SDR receiver at the same time. This allows me to view a wide live bandscope on my computer using SDRUno and control the HF radio via Omnirig. To see this in action please search YouTube for Tech Minds.
