Charles, i'm thinking of selling mine also but no idea what the rig is worth. Did you find a buyer? BOB AF2DX

Hello.? I'm cleaning up and downsizing and don't know if anyone would be interested, but I have a unbuilt KN-Q7A with crystals for 7.200-7.220 still in the USPS box as received.? If anyone might be,

Hello, New member here.? I finally got around to finishing up this transceiver that I got from Ebay a few years ago.? It's uses DC conversion with the KK7B-derived phasing technique to generate and

I pulled the 1uf and 103 near pin 8 or NE602 and it still works okay. Really cute little receiver! Thanks, Adam

If I connect this radio to my commercial radio, the carrier leakage will drive S meter to about S9 in CW mode. Pretty interesting and it could be used for S meter calibration? Thanks, Adam

Since the Li-Po battery pack of correct size is not easy to find, I modified the circuit a little bit to be compatible with rechargeable Ni-MH battery of 8.4 volt. The amber LED is used to decrease

I have plenty in stock. I am selling at 1 USD each. Thanks, Adam

I am guessing these are no longer manufactured. More translations landed me with this image: http://www.learnmorsecode.com/DC/hambandcoil.jpg

Did you hand craft or buy the DIY7-7 coil? http://www.learnmorsecode.com/DC/DIY7-7.jpg

Correct. The 1uf will filter the supply. 64 ohm means 32 ohm + 32 ohm. If you use voltage like 6V or higher, you can also use 300 ohm + 300 ohm like HD600 to achieve higher gain. I know it is hard to

I pu tthe images here just for discussion. I cut out the Xed parts..... and got this:? http://www.learnmorsecode.com/DC/rong1.jpg Am I reading this correctly? PLUS VOLTS? to the NE602 is after the

Jim, It is a direct conversion receiver but I changed LM386 to 2N3904. The X on a .01uf capacitor means it is totally removed. The tuned inductor is DIY7 series with built-in capacitor. I built 7.050

Hello Adam. Some questions about your circuit.? First I see no information about the tuned inductor.? What did you use?? Second,? you have an X through a .01uf capacitor on the collector/output of

Gang, Here I show you my recent project. Inspired by the receiver portion of VK3YE’s tiny toy CW transceiver (search YouTube videos to know more about this radio), I wanted to build a small receiver

Gang, I plan to clean out some items of my stock so I have the following additional discount (still free shipping but 10% off for 2nd purchase will not apply) available until the end of this year.

It seems that the photo did not show correctly. Here it is. Thanks, Adam

Gang, I made some changes to the mini whip to keep the 2nd stage 2N5109 amplifier and add a relay to switch my end feed half wave antenna, so I now have two antennas, with and without amplifier. I
