Have u done the mods yet Steve? Btw have u got a AM BCB filter on yours and is it my mixer or is urs also seem a bit deaf on RX?

The SA602 only requires a 50 mV p-p signal to fully unbalance it. Larger signals create all kinds of unwanted mixer products. Since the VOX requires a 1200 mV p-p signal to trigger it, there needs to

I bought this antenna when Adam first announced that it was available . Since I have to depend on my grandson to do my antenna work for me , due to my physical limitations and he was able to easily

BG7IKK did it again! Now with N0FW with distance of 12821km. Thanks, Adam

Correct. This modification is made by BH4DCL and it is smart. Thanks, Adam

Hi Adam! So just replacing C5 by supplied 105 Will work? No other modification? Thanks De: Adam Rong Enviado: sábado, 27 de julio 20:57 Asunto: [crkits] D4D: Part List Updated with IMD mod and more

Folks, For the IMD mod, I mean I opted for the new modification method described in Modification Possibilities 5 instead of the first one. it will make life easier since I can supply the 105

I've got $1 ebay USB sound cards and they work fine for the VOX,the only problem I have is the radio is deaf and wont go on freq no matter what but atleast the VOX works

Folks, See this: https://groups.io/g/crkits/files/D4D%20Kit%20Documentations/d4dpartlist20190728forMP_80_40_30_20.xls The changes are marked in blue. The IMD mod becomes easier if you just replace C5

Adam, Thanks for the info, I ordered the $10 unit. Mark

Mark, The newer generation built-in sound card has to meet an European hearing protection standard EN50332 and the max output voltage will not exceed 150mV on a 32 ohm load. This is the reason why

waiting for my d4d kit... i have just received two new RPi4s (2GB and 4GB); they seem 'faster' running many applications... i'm hoping that the additional memory and faster CPU may help with some

I've tried several sound cards including an external USB unit. None are powerful enough (volume up all the way, 1500 Hz signal playing) to trigger the D4D VOX. What type are others using?

And I just updated the Mini Wire Antenna manual to Draft 2 version. Thanks, Adam

5W is fine for FT8. -- Thanks, Adam Rong

Adam, how many watts is the smaller toroid good for? I would assume 5w. thanks simon
