Hello Vincenzo, All,<br>
<br>
I think it would require some similar changes like for Mercury:<br>
<br>
- Change the AD9744 DAC-clock to 12x12,88 =147,456 MHz.<br>
This is a 210 MSPS device, so I think this would not be a problem,
not sure though, maybe there are other problems.<br>
Furthermore there is a 65 MHz (?) low-pass filter present that
should be changed to >70.5 MHz (4m band assumed to go from 70 to
70.5 MHz.)<br>
<br>
- Change the Penelope / Pennylane FPGA / DUC (Digital Up Converter)
code to accommodate the new band<br>
<br>
- Change PowerSDR/KISS code<br>
<br>
But I hope others will chime in and can surely give better comments
on the modifications which would be possible/necessary.<br>
<br>
73's,<br>

What about Penelope/Pennylane, is there a way to modify it to
transmit on 70MHz ? <br>

<div dir="ltr"> Hi Henry,<br>
<br>
You can speak with Gerd DJ8AY. He has installed a LTC2209 so
his Mercury has Rx capability up to 98 MHz.<br>
Anyone can order this Mercury to Gerd.<br>
