The site provided for information is not accessible from India as due to the COVID crises all China sites are banned for accessing from India. Can any one will download the contents circuit diagram

Also Adam, it would be absolutely fantastic if you could guide us to a manufacturer in China that produce good copies of now defunct transistors. There are many on ebay as you probably know. It would

Adam, snap to a grid of 0.1 mm if you do a pcb. I'm not sure there will be many takers due to the amount of same frequency crystals which are rarer than unobtanium any where else other than China.

Thanks for the update Adam. The HT-1 has been a fantastic little rig. It was my only communication during a bad winter storm when our electricity and phone/internet was out. I'll check in from

Currently the stock is empty. I will let you know know once it is available again. Thanks, Adam

Check out the video for a real QSO with DS2 station. https://mp.weixin.qq.com/s/LsT_6HOdcZIj5bBtD9kOjw The schematic is now in the file section as you may have noticed. It could be a kit but it

You are right! It's past midnight for me and I wasn't paying attention. I have small eyes ... ;-) J3 is the microphone connector and J1 is the headphone connector.

I don’t have plan for a new CW kit in the near future. However, the CRK-10A can be back easily when it is required. Thanks, Adam

Hi Fox, The Q3 is a receiver audio amplifier. Thanks, Adam

We thank you! I don't understand the configuration of transistor Q3. Installation with common emitter ... Can you explain it? Thank you! -- Fox

Any future kits planned for CW ops? Sent from my Verizon, Samsung Galaxy smartphone

i cant seem to place an order in site for d4d js8

hi adam the d4d went together very easily and is working well on 20 m i am thinking of building another for 80 m i already have the crystals so can you give me a price for an 80 m version less

I will prepare schematic once the test and adjustment is finalized. Thanks, Adam

No. This is the result of a design challenge. It is 40m only due to crystal. It is more complicated than D4D. Thanks, Adam

Hello all, I have for sale 2 PCS of KN-Q7A SSB trx 40m version fully functional, airpot for tuning, bigger 3D printed knob. QRG 7.110~7.130 MHz 20m version,not working at the moment, mechanically

Is it planned to replace the D4D? 73 - Pierre - FK8IH
