Hi all wspr followers. I have been mounting a 30m band, Stand alone WSPR beacon.
It includes:

- Main Board (W3PM design. Universal VCXO WSPR Controller with PIC 16F628 software).

- Colpitts Crystal Oscillator + Power Amplifier 100mW (30m QRSS hanssummers Kit, with litle mods).

- GPS (to update grid and clock automatically)

It need only 70mA in stand by, and 200mA in tx mode. Power suply 5v-14v.

Hi all, some days ago, and now, here in Spain all Om's are receiving brutal interference between 10.136 to 10.160 Mhz. 30 m Band.
We need your help to determinate who is making this interference.
Please, check it, and report us if you receive this.
Many thanks for your colaboration. All reports are welcome!
