Yes, you have to buy the RF Deck board or supply your own. The support kit has supplies that will supply 50-60 volts and a heat sink and heat speader that will work with a number of RF Amps. I see the

Hmmmmm, I did not catch that, yea even pricier…. Regards, Jim Allen jim.allen60@...

#eladduo

Don't you then have to buy the $500 RF amp board too?

#eladduo

Just got this today, This is a HF RF amp that works with the Elad 5 watts in 500 watts out with an antenna tuner… It’s a bit pricy at $1,200.00 Regards, Jim Allen jim.allen60@...

Just a note that the Hobby PCM Hardrock 500 Power Amplifier Support Kit is now available for sale. The support kits contains everything you need to home brew a 5w to 500w amplifier. I have completed m

Wow, I am glad I found this post because using the manual alone you would never figure this out and make the PC microphone work. Mark, thanks so much for putting this out there! 73 Christoph, NE7EE

Vianney Yes, that was it, thank you so much. Now my panel looks similar to Mark's and i can see the waveform being displayed and power on RF output with SSB. Many thanks, Mark.

Hello Mark, try to uncheck this check box and restart the software. "Use FDM-DUO TX Control Panel" option activates the "FDM-DUO TX Control" panel which is not fully working. With this option unchecke

OK, so I tried to check everything from the basics upwards Here you can see the microphone is working - I am getting a signal on the windows sounds dialog: Although I have permission for desktop apps

#eladduo

Thanks for the suggestions, I'll give it another try this morning. Regards, Mark.

Look at your wave out setting. It should be the “Line ELAD FDM DUO Audio device” Regards, Jim Allen

This is me humming into my Heil headset plugged into the MIC port on the front of the computer. Does your Win10 installation think that SW2 doesn't have permission to use microphone devices? Neil G4DB

#eladduo

I found the TX control panel but it would appear that no matter what settings I try when pressing the PTT button in USB mode the microphone produces no output. I am using a Panasonic Toughbook. It has

Hello Paul, I would start with reading the note by Andy first. You can find it here: http://www.g4jnt.com/FDM-DUO_at_VHF.pdf Indeed, I use the DUO with a DB6NT transverter (3cm), or my own (13cm), but

Harke, Thanks for the good news. I want to use the Duo as an IF radio for a Khune transverter. Do you also use a filter on the TX output? Should I use a bandpass filter centered at 144 MHz or a 122 MH

#eladduo

Gentlemen, Allow me to throw some experience in. A couple of years ago I was looking for a decent 2m sdr and I was unimpressed by the market. Either not good enough or too expensive. My application is

#eladduo

Are you using this 144 Mhz filter / amp design with your Duo? The Duo as a 28 MHz IF radio is excellent. I use it on 432 and 1296 MHz. No I better understand the limitations at 144 MHz undersampling.

#eladduo

Hi Paul I use a G4DDK Anglian transverter to get the DUO on to 144, but it is quite simple to get around the mathematical and technological issues with the DUO at 144 MHz. Running 144 MHz on a 122.88

#eladduo

Neil, Do you use a 144 MHz IF with your 10 GHz system. I tried using my FDM-DUO configured for 144 MHz with a Khune transverter. I was not successful looking for the beacon. 73 - Paul - W2HRO
