John, I am not very sure, but probably because the attachment is so big that Yahoo blocked it. Does anyone see the pictures? Thanks, Adam

Hi ADAM. No family here so things are quite on holidays. Making Contacts is hard with all the QRM but did manage. A few 1 to 200 miles aways big DX but it keep my CW up. Have a nice Holiday BOB

Hi Bob, Good to hear from you again. Take care of yourself and your family. Here in China, it is a national holiday equivalent to July 4 in US. We have several days off, so we will plan for a family

Still here but in the hospital again with my HB1B QRP radio To much QRM but copy strong stations OK. 73 BoB AF2DX Sent from my Verizon Wireless BlackBerry

John, Of course it will work with a TCXO if you need better stability. TCXO is an active crystal, and the accuracy is very high, so I suppose there is no need for calibration. Thanks, Adam 在

Hi Adam, What considerations should be made to replace the stock crystal oscillator with a TXCO (Temperature Controlled Crystal Oscillator) on the Sandwich VFO for greater frequency stability when

Adam, I don't know if it's just me, but I'm not seeing any pictures of your Pixie2 project with your message here on the CHINA_QRP Yahoo forum. 73, John AA7US ---In CHINA_QRP@..., <rongxh@...> wrote

Gang, I made this popular CW radio on 2 units of Choc Perfboard today. The circuit has a 2N3906 acting as TX/RX offset as well as sidetone control (which is my modification). I plan to add a OMRON

You can make the conversion, but it might be more fun to just buy a CS-15/17 radio. The filters are different and it is difficult to remove the DIY7-7 coils and replace them with DIY7-21 as well as

Hi Mike, It is possible to make the modification. Likely you will get about 2 watt PEP on 15 meter band. You will need to order the following from CRKITS.COM offline: 1

Group, I have an old KN-Q7A that was on 7MHZ and I want to convert it to 21MHZ. I seen that the CS series possibly can do 21 MHZ and the CS Looks very similar.can I buy a CS lit for 21 MHZ and

Attached is a bandplan for the US, but there are also several other frequencies that also might open up.

Adam, Here in the USA, the 60M band is comprised of 5 each 2.8 kHz wide "channels" centered on 5.332, 5.348, 5.358, 5.373 and 5.405 MHz. Since the FT8 digital mode is currently being conducted on the

Chris, Thanks for coming back. After receiving my Master of Engineering degree in computer science, I started my career from 2003 as a project manager to develop laptop products (like ThinkPad SL

Hi Adam, Thanks for sharing. What is your professional work? I always assumed that your kits were your primary business/work. It never occurred to me that you may have a different job. Chris

Gang, I found many videos on YouTube about these very low cost Chinese QRP kits. As a benefit of this group, I would like to introduce a little bit about the background. Back in 2000, when I was

Gang, Recently I heard China is going to open 60 meter amateur radio band as well, with the power limit of 15 watt (EIRP). I suppose CS-series would be good for this purpose. As I am not very clear

I am announcing the availability of three new kits which when added to the Sandwich will give Frequency Readout. If you have any questions, please let me know. An upgrade to the Sandwich code is

Digital modes are a lot of fun, and CS-series or KN-Q7A plus Sandwich digital VFO works great so far with the specially made firmware by JH3BTK. Larry's modification to add a OLED display seems to be
