Radio hacking with TaoTronics Bluetooth transmitter

Indoor shortwave listening outside the shack

I was inspired by the following 1930s illustration from the book On the Short Waves, 1923-1945, which describes how a seasoned DXer would have listened to shortwave around the house

I achieved a similar result by combining the Nikkai AV sender/receiver pair and the TaoTronics BA01 portable Bluetooth transmitter:

Monitoring while recording from radios with no line out

Tecsun PL-660 doesn't have a line out, which means that when recording from it one has to use a pair of headphones to listen to it simultaneously. Most portable speakers I've tried generate tremendous amounts of RFI when connected directly to the receiver. I solved this problem by using TaoTronics transmitter and a Bluetooth enabled portable speaker, together with a cable that splits the audio output into two, so the transmitter and the audio recorder can both be connected to the radio. The recording is of Radio Australia and was made in London, UK on 09/04/2014 at 15:43 BST.

Perhaps one day we will see a decent portable shortwave radio with a built-in Bluetooth audio transmitter?
