I have two genuine Raduino cards. One that's been used (the only modification to both of these cards is a 47 ohm 2 watt resistor in series with the 7805 regulator to drop the voltage a bit so it doesn't have to work too hard at input voltages of 12-13 volts DC. I've also re-located the 7805 to the back side of the card so it doesn't get in the way of things. The second is basically new except for the 47 ohm resistor mod. Oh and both of these have the 4.7K resistor on the CW input installed between pin 2 and pin 3 so you can connect pin 2 directly to the tip contact of your key jack.
I am not going to use either of these Raduino's. I'd like to get US $20 (plus shipping) for the older one and $25 (plus shipping) for the one that came in the kit I just got last week.
Please, if you're interested, lets take the discussion private so as not to clutter up everyone else's email. My email address is good on QRZ under W0EB. I'd prefer to ship to US addresses as the minimum international shipping for these would be $14.25 US.
It's 10:30 p.m. here and I'm going to shut down for the night so I won't be able to answer any emails until tomorrow morning (US Central time).
