why not swap out the female pl259s for some chassis mount BnC jacks and not use the adaptors.
Yes would lower insertion loss. I still need to check this out. Thanks for the comment 73 de VK2AOE
Mate, looks like a perfect switch for SDR pan adapter. Will have to investigate it. Good content as always.
Yes it works well...but if you like SSB, you will need to use the PTT input as the relay chatters (i.e. it works but will drive you mental with the noise without it). Thanks for the comment. Been having fun of late!

I'm trying to free up some time so I can setup my workshop.
Time, time, I wish I had more time! Two Yes's. Yes the construction looks to be very sturdy and well put together. Yes, there is nothing like single malt. 73 VK5WB
Yes...but too many times the single malt has resulted in the release of smoke!! 😆😆🤣🤣 73 de VK2AOE
I just received one in the mail. I thought I would need the PTT connection to a radio to disable the transmit to the SDR. Does it just disconnect when you transmit? So you only have power, antenna and sdr connected?
Technically yes it disconnects. Other users I researched said quick enough not to damage SDR. I use 5 watts QRP and it worked without PTT and didn’t cook my Airspy SDR …. BUT on SSB the relay chatter will drive you mad and wear the relay out prematurely. Also I’m yet to check attenuation on it. It also will not detect lower QRPP type rigs ( which is what I wanted it for). I did hook up the PTT on my Hermes and it worked well that way (less clatter etc). 73 de VK2AOE.
Does the mfj 1708 .. have that feature of Dual Receive when jumper is removed ???
Sorry not sure about that? I bought the switch as I’m going to build a receive only loop to use with my Airspy SDR receiver. 73 de VK2AOE

Too much insertion losses on this device
Great! I have one too, i was think about to make a mod for J5 jumper and put a "on/off switch! on the front but if i do need to use cable and those need to be shield can make interference or or problem? 73 de iz3qvb
Actually not sure if the switch would cause a problem? My guess would be it would not cause issues… but ONLY a guess ! 😂 73 de VK2AOE
