Sandwich Digital VFO Complete Kit
This simple yet
useful si5351a and Arduino based digital VFO is a great addition to KN-Q7A
and other single conversion SSB radio. The innovative one LED frequency
display is amazingly easy to count and read the operating frequency. SMD
part is pre-mounted.
The assembled kit is as shown on the left.
2 Choc Perf Boards for RF Experiments Plus
The Choc RF Perfboard is designed by BD6CR to facilitate RF experiments and prototyping. The pad pattern will provide great
convenience to fit in discrete parts as well as IC and even 7x7 IF
transformers, and good RF performance with modular design with grounding and
shielding can holes around each unit. It is easy to break into small units.
The 3 x 4 unit board fits the metal case of KN-Q7A very well. The video
takes BITX-40 and VK3YE Knobless Wonder as examples to show how easy it is
to use the Choc Perf Boards. The following article was published on 2018
Sept/Oct issue of Amateur Radio magazine by Wireless Institute of Australia.
CS-series SSB Transceiver Kit with Speaker Microphone Combo
The CS-series supercedes the KN-Q7A. It inherits 6-pole
crystal filter, MC1350 IF amplifier and rigid metal case. Also, it integrates
Sandwich digital VFO to have wider frequency coverage and better frequency
stability. A few more enhancements are also added. Speaker
microphone is added to the standard configuration. Besides SOTA,
consider HF digital like FT8?
[The previous generation KN-Q7A was widely introduced by CQ Amateur Radio magazine in US, CQ Ham Radio magazine in Japan, RadCom magazine in UK, Amateur Radio magazine in Australia, and some other brief introductions in other countries since 2012.
