<div><font face="Arial">Yes, you need to modify the filter at the output of the
preamp (LTC6400-20) to increase the bandwidth but it works quite well.
Without any other mods I can hear the local FM repeaters fine. For serious
work you will need a low noise preamp and suitable filters. </font></div>

<div><font face="Arial">By fitting an external bandpass filter between JP2 and JP3
you can also use Penelope on 2m.</font></div>
