Hi,Regarding the problems of operating with the THD-72 ( or other portable ) and avoiding the tangle of wires etc.Patrick WD9EWK/VA7EWK mentioned that he has a "Bluetooth" speaker with a jack socket.
It is much easier to obtain a a " Bluetooth" audio transmitter and thus avoid the need for any wires.   These transmitters are  reasonable cheap and available from a number of well known sources.Simply plug the Blue tooth Tx into  THD-72 audio jack and pair with the Bluetooth  speaker  - You canadjust the THD-72 volume control to suit your conditions.The size of these Bluetooth transmitters is sometimes smaller than an SDR dongle,  some even have a wired jack plug fitted.
I have used this method not  only for portable operation, but also for demonstrations, It  made it much easier for those listening and myself of course."WIRELESS" Hi Hi.

PS.The method can be used with many other radios etc and I have used it to set up my LNB/dish      to monitor QO-100 down link/  beacons and operators.  (  An AOR receiver on 739 Mhz SSB )
