First, twist the pair of wires together as per the instructions. You'll have a red wire and gold wire at either end of the twisted pair. After you wind the toroid, you will connect the gold wire on one end to the red wire on the other end. (Leave a short section untwisted at either end to facilitate this.)

So, go ahead and wind the coil. When you are finished, all of the loose ends should be fairly close together on the toroid. Take the red wire from the start of the twisted pair, and the gold wire from the end of it. Now, twist those two together.

You will be left with one red strand, one gold strand, and one strand of red and gold twisted together. These are the three legs of your completed toroid, ready to be soldered into the board.

Okay, I checked my D4D parts list. For 20m it's 11 turns of 20cm of wire for both L2 and L3. I've attached the screenshot: hope that helps!

Re: Use scope to check audio input level to D4D?

Adam Rong
 

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 overtones in audio range will reflect the distortion.

You will have to find a balance. The recommended modifications will give you good balance.

Thanks,
Adam

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 other is simpler...Replace C6 with a 0.1uf cap and C5 with a 10uf electrolytic...This capacitive divider ratio should accomplish the same thing and keep the mixer from saturating...Expect your power output to be significantly lower but with much greater spectral purity...Without the mods, the signal is about 75KHz wide!...I'll report on my testing later after I have access to the spectrum analyzer and wattmeter again...Jim  WB2LHP

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 indicates an overload of the D4D's audio input circuitry? I realize that it's possible to look at the RF output for signs of trouble but I'm wondering if it's possible to do so further upstream in the circuit.

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 PayPal.

Thanks,
Adam

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 and you can't beat the price...Jim
