Hi Barry, I think whats happening is the kit is waiting for the next transmit cycle so you may just have to wait a while after powering up before you see anything on the lcd. Did you have any

Hi Mark, Take a look at W3PM's website, QRSS and WSPR designs using both Arduino Uno and Mega boards along with the code for both AD9850 and 9851 DDS boards. The AMQRP DDS-60 can easily be

Hi Gang My Arduino shield configured for a simple FSK callsign TX has simply amazed me with the reports I have received from my 50mW and 30M dipole. What I would like to do now is try some very low

Is that a 'Denco' filter? :)) Do you remember the Denco plug in coils? long ago, I had a regenerative receiver kit that handled band changes just like that. They were really terrible things, they

Done a mod today to make use of Hans pluggable LP filters... Mounted the filter sockets on some PCB on the lid of the case. These are coax wired internally and I can just swap out filters without
