NOTE: Due to high demand, the relay-switched filter kit that is part of this deluxe set is out of stock currently. You may PRE-ORDER on this page. Your entire order will be shipped together when this item is back in stock (expected second half of January). 

This is a set of all the ktis you need to build the sinewave output signal generator described in App Note AN006. Using VFO kit firmware s1.03 or above, the firmware can operate the VFO/SigGen kit with the 6-band relay-switched LPF kit, and six LPF kits. It automatically selects the optimum LPF for the operating frequency. The result is a high quality sinewave. In the prototype measurements, the output was a flat 10.8dBm +/- 0.4dBm across the range 2.9 to 34MHz with worst-case spurious outptus at -45dBc.

Sinewave HF Sig Gen set contents:

Optional extras:

  • QLG1 high-sensitivity GPS receiver kit, for GPS discipline of the output frequency to better than 0.1 parts per million
  • VFO enclosure kit, drilled, printed, and with controls, connectors and accessories. Shipped separately from China by airmail
  • OCXO version of the Si5351A Synth kit
  • 20mm knob for the rotary encoder

The kits are easy to build, with through-hole components only (no surface mount soldering). 

NOTE... LPF bands: if you want to have different LPF bands than the 6 listed above, that is fine! Please specify the required changes on the customer notes entry in the order form. 

NOTE... GPS: All the above kits will fit together inside the optional enclosure. However the GPS patch antenna cannot work through a metal box! So you must either arrange for the GPS receiver to be outside in its own box, or you need to use an external antenna and run some coax into the box.

Please read the manuals and understand your kits before purchase. 

Printed instructions are not supplied with the kit! You need to download the following PDF instruction documents (click links to go to the web page where you can download the document):
