skinkie:
The broadcasting transmitter (105MHz / 190MHz) is about 1.5m lower than the Pi is currently standing. If this will never going to work without shielding that is something I would like to know. Yes, I bought the “plus” stick because I assumed (wrongly) that the function would be exactly the same. If this is not the case I do hope this is going to be updated.
The 105MHz - 190MHz transmitting antenna only few meter away will sure saturate the front-end of dongle even if the height difference is 1.5 meter.
You do need
A Filter
Shield your equipment by wrapping in a copper gauze connected to shield of coax and the USB shield.
Keep your equipment as far away as possible from the RF Pump (i.e. Transmitter Antenna)
