In support of requests for monitor stations ,

Listed are a set of links to enable the £5 usb dongle to be used as
SDR-RX , it will benefit from preselectors / filters / pre-amps etc , but the
initial out lay of £5 is minimal compared to the results and quality of the
supporting software is excellent , as well as the SDR )

Performance on HF is 'good' and benefits from a ATU or better a
pre-selector , The later dongle will cover 1500 MHz down to 24MHz directly

A modification is needed to access the direct sample mode , attaching a
wire and cap .. the video listed is using the wire+cap method , alternative
is to use a transformer , taking care the core is rated at the band is
question

MF and down , the 'gain' falls off , I have good results using the 500k
tx-atu , the Mini-whip Ae seem's to offer a reasonable solution , and can be
seen operating > http://myweb.tiscali.co.uk/wgtaylor/grabber2.html
