At the moment I am doing some local tests to see if people can copy 10mW ERP on 8m locally. This is the UK ISM limit. As calibration, I am sending 1W WSPR on 8m before trying 10mW ERP. Initial tests suggests this is too low to be copied, but might just be possible with 2el 8m antennas.
UPDATE 1928z: This is an update on the 8m ISM tests locally so far. At the moment, I expect to switch to 10mW ERP WSPR later this week with the call 8M3ISM. A 20dB pad will be added right next to the FT817ND.
- Judging by the 1W WSPR reports so far, I feel it is unlikely people at any distance will copy my 10mW ERP signal.
- One of the issues is a high local noise floor.
- With 8m horizontal antennas, I suspect many would copy my 10mW ERP WSPR.
