Folks, It will be great time to try 80m. Remember, we have the 80m version of D4D. Thanks, Adam

Thank you and have a great week. John K2JHU...

If you don’t have RF test equipment like spectrum analyzer, you can use WSJTx spectrum to make rough judgements. Transmit with D4D and receive with other rig and observe the received spectrum. The

John, I have an over time and full time job, so the shipping will be every Monday. Your rig will be shipped next Monday via EMS, and after shipment, the tracking number will be updated in

I've been working on this issue also Adrian...Right now I'm testing two solutions...The first is to incorporate the KD1JV resistive divider mod...I use a 33K/1K combo to get the level I want...The

Hi All. I'm curious if there's a point in the D4D circuit that would allow for an easy check of the input audio level using just an oscilloscope. Can one look for clipping (or some other symptom) that

Hi Adam. Just wondering if you have any idea when my rig will be shipped. John K2JHU...

I don't own the HT-1A...I bought and built the D4D FT8 radio...I applied the recommended mods and it works very well...It will be my QRP Field Day rig using a solar panel and battery...Great quality

Jim I just order he rig.So how well do you like the rig. Any thing I should know up front. John K2JHU... wrote:

Adam the funds are on their way. John K2JHU...

OK Adam. I will place my order today for the assembled HT-1A. Thank you. John K2JHU...

Correct. I am in Shanghai China. I can ship via EMS express shipping. Thanks, Adam

No...He is in China I believe...

Thanks you Jim. Are they the ones in the UK. John K2JHU... wrote:

I also got no response from the US seller...Went instead to the designer and ordered direct...It was here in 2 weeks which I thought was very reasonable...I would order directly from CR Kits...

I have sent 2 e-mails to the USA site asking if they have any assembled radios with no response. I would really like one of these radios and thought shipping from US location would result in a faster

Will the D4D work with Fox / Hound Dxpeditions?

Hi Bill, The power meter is a cheap one, I didn't opened it but I assume it's? rms voltage sensing with some assumptions on how to change it into a power meter; the value yield it's very low in my

Both thermocouple and themistor type power meters measure True Power. Rather than indirectly measuring the power by measuring voltage and using a meter calibrated assuming a sinusoidal

This is a double sideband signal. Remember, there are two signals and being generated and only one is being received unless the receiver on the distant end is a phase locked DSB receiver. The
