Re: 2 CPK-4 plus an AM radio make a complete station

I can vouch this approach works well provided the band isn't crowded.

Re: 2 CPK-4 plus an AM radio make a complete station

Inspired by this idea, I just submitted a short piece for QRP Quarterly.

?Guys,

CPK-4 can work with a SSB receiver to make a complete station. If you just have an AM radio receiver, you can consider 2 CPK-4. Photo:

Take 7030 kHz as an example, you can tune your AM radio receiver to 7030 first. You can use the whip antenna or a separate wire antenna. You should hear no CW signal. Power up one CPK-4, set the jumper to GND and fune tune the trimmer capacitor to keep it oscillating at 7030.7 kHz. Adjust the distance between this CPK-4 and the AM radio receiver to receive some signal. If you put them too close, the AGC will suppress the incoming signal too much, so you should put a bit far away so you can hear the signals in some background noise.

Now, you can power up another CPK-4 as TX. Set the jumper to KEY, fine tune the trimmer capacitor so you can transmit on 7030 kHz and connect a dedicated resonant antenna for TX.

Now, it is ready to grab some QSOs!

Thanks,

Adam

Adam!? Thank you!? The little kid in me was desperately looking for a public web-888 to play with when I am awaiting shipment!??

Re: Testing RX-888 MK2 High Performance SDR

#5032

Yeah, sorry Adam.? My CRKits money for the next couple of months went to ordering one of these.? The Tech Minds has a very good video on this device on YouTube. I have a remote location that I want to leave this at so it probably will solve an ongoing problem for me hopefully.

?

I will let the group know what I think a week or two after I get one if you think it's appropriate.?

?

It's a fusion of a Red Pitaya clone (duo), a RX-888 mkII and a KiwiSDR... Runs all the KiwiSDR extensions of openwebrx except for tdoa and HF-DL at this time. So yes, it can be a full hf band skimmer for WSPR, FT4 or FT8.? Does 13 channels will ALL of them supporting waterfall. It's interesting and it is a good price for that horsepower.? ?Can also be used as a GPSFO and as long as it has a GPS antenna it will self discipline the frequency stability.?

?

Just researching all of this will take you down a rabbit hole.? However it's very educational.?

?

Aliexpress US tells me it should be here before October 2, but unfortunately I trust them as far as I can throw them.? I really wanted one so I lifted my ban on Aliexpress.?

?

I am still looking for a URL of a publically hosted Web-888. I will share it if I find one.?

I have a Tecsun PL-368 and it is a great compact receiver for CW and SSB reception. The tecsun plus the CPK-4 make a fine combination.

Hi Gary,

You just caught the last bus of 25 bucks for 3 CPK-4 kits.

I have just published the manual, video, and price. You guys can order directly from my web shop now.

Thanks,

Adam

Guys,

I have done the test and the performance is consistent. You can make PayPal payment 25 USD each set of 3 CPK-4 kits (7030, 10106, and 14060) including shipping directly to rongxh@... and leave your ship to address. The assembly manual will be available in the folder [email protected] | Files no later than September 18.

Thanks,

Adam

Jim,

Thanks for your interest. I will ship a few next Monday. The early bird price is 25 USD including shipping for the assortment of 3 CPK-4 kits: 7030, 10106 and 14060. The RF output is 300-500 mW at 9V, higher than PIXIE2, especially for 20m band.

Thanks,

Adam

Guys,

CPK-4 is a crystal controlled QRPP CW TX. I wish to offer 40, 30 and 20m on QRP frequencies. It works with any SSB receiver on hand.
