I am looking for a better method to transmit DFCW for 2200 meter QSOs. For my QSO with 2E0ILY I used a QRP Labs U3S for the transmitter. This worked very well for DFCW60 when I was transmitting every
Depends how proficient you are with PIC or Arduino or Whatever programming. There are still AD9850 moduiles to be found on Ebay - that are not completely obsolete or sold-out yet. Write your controll
Hello Alex, This is very interesting! Google Translate does a very nice job of translating the web page to English. Now I have to download the files and take a look at the schematic. I will also down
Thanks Andy. I have no proficiency at all in PIC or Arduino programming. In my younger days I wrote some reasonably complex DOS programs but a lot has happened since then an the old brain isn't what
Paul, One approach Ive been considering is using an Arduino to generate DFCW. The book Arduino Projects for Amateur Radio has several related projects (CW Keyer, frequency generators, etc.) that coul
Hi Markus, Mine too! I would strongly prefer that every exciter and amplifier be linear but sadly that is not the case in my station. The other monster in the chase is frequency stability. ;-) I do h
The Elad FDM-DUO will Tx down to DC (well, 10kHz really), 0dBm from a low power port and has its own internal soundcard so Tx level is always matched perfectly when using digi-modes. You just nee

Hello N1BUG, Sadly VK3RF has stopped making these, I have had one in my TS-590S for years and it works great. Disconnect the Trimble Thunderbolt reference and it reverts to its own TCXO. There may be
Andy, The FDM-DUO looks good. For me it's the same issue as fixing the stuff I have... a purchase of that magnitude requires 2 years of budgeting. It is definitely worth considering, as it would be a
