The new SDR-Control app that lets you use certain iCOM radios as remote controlled SDR stations for Macbook or iPad does not yet (May 2022 now) officially support my iCOM IC-R8600 but Marcus Roskosch from https://roskosch.de/ told me that he recently purchased an IC-R8600 and the app already works on an experimental basis. I immediately bought the app, installed it on my MacBook, connected a network cable between home router and radio and tried it out... I also show how I use bhi DSP units to filter out noise to enhance speech at the radio and at the computer audio.

The new one performs well, in part thanks to the tuning & impedance knobs. I compare it with the GRAHN SE3 and a big home made loop that I bought second hand. The latter has no tuning but is as directionlly sensitive as the others and it delivers an amplified signal to the receiver. I found a manual for the QRP, not included in the package: Instructions for use of BH5HDE QRP portable small loop antenna Welcome to use the BH5HDE QRP portable small loop antenna. This product can easily and quickly set up a short-wave transceiver antenna, allowing you to enjoy the joy of multi-band reception and communication indoors, windows, balconies and outdo
