Here are some of my favorite kits.
Controller and Frequency Generator Kit #2
This standalone unit has a frequency range of 3.5Mhz to 1417.5Mhz
(yes, 1.4Ghz) depending on the Si570 part used. I have tested it up to
1200Mhz which is as high as my scope will go. Really an amazing, low
jitter, and very low spur levels chip. You can go to the SiLabs website
and look at the specifications. All setup and control is via the rotary
encoder knob and it's push button. Power is battery (3V) or external
power (5V-12V). It's compatible with all Si570 CMOS and LVDS versions,
single ended or differential output, and any default frequency. This
makes an ideal signal source for SoftRocks and many other projects. The
Si570 Controller and Frequency Generator Kit includes a 12 digit LCD
frequency display, a programmed MC9S08QG8 microcontroller, and a rotary
encoder for tuning. It can ordered with a CMOS Si570 chip which is
speced at 3.5Mhz to 160Mhz. Using other LVDS Si570 parts, the frequency
range can be extended up to 1.417Ghz.
Digital QRP mWattmeter Kit #9
20W HF Amplifier Kit #15
was to provide a
good and low cost Amplifier for the HF bands (160m to 6m) which can be
driven by a SoftRock SDR or any other low power driver and provide
20dBm of gain. Low power being defined as less than 1W. Some of the new
SDR units supply less than 50mw and really need a little boost. This
Amp uses well received RD16HHF1 RF MOSFETs which are each rated at 16W
output for 12.5VDC at 30+MHz. These parts are quite robust and much
better than the IRF510 Switching Power Supply MOSFETs used earlier,
largely because of their low cost and availability. The other advantage
of the RD16HHF1 is that the mounting tab is attached to the Drain pin
which is at ground potential so no mica insulator is required. The
Amplifier has a Signal Operated Switch (SOX) for CW QSK. I didnt really
put it there for SSB ..but who knows (still better to use PTT). Did I
mention good and low cost ?
I built one of these for my Hermes board ( ANAN10 ) very linear and works great!!
PIC 16F876A 500MHZ
Dual Channel RF Power Meter with Data Logger: PM3
PM3 is a version of PM2 with Data Logger Output and
supports remote LCD & Menu Button placement.
The MiniVNA and the MiniVNA PRO
one of my favorite tools!!
Toroids and filter kits
this is the place !
