In order to receive the Grimeton SAQ transmissions I am using the Flex-1500 together an active whip antenna and the VLF-LF-MF band up-converter from Heros technology.
Occasionally I use too my old Trio TS-830S working in parallel with the Flex radio for so the IF output of the VLF converter is derived to the antenna input of booth radios by means of a signal splitter device. The system works fine on all the VLF to MF spectrum covered by the converter.

  I am using a homebrew and homebuilt converter, no commercial stuff. In this converter there is a very high impedance amplifier included, so that a short rod antenna around 30cm is enough to pick up SAQ with good SNR. With a 1m rod it becomes much louder 😀
