All QRP Labs kits may be ordered online securely at the shop, with PayPal payment. QRSS, Hell, WSPR, Opera and PI4 slow-signal modes anywhere from 2200m to 2m and even 222MHz bands. Plug-in LPF filters are available for all This Band Pas* Filter (BPF) kit is for receiver input filtering. It uses the popular double-tuned-circuit which is reliable and easy to build, without needing access to any special equipment. Kits are available for 10 HF bands 160, 80, 60, 40, 30, 20, 17, 15, 12, and 10m. The kit uses a high-quality double-sided PCB with silk-screen, solder-mask and through-hole plating. The capacitors supplied with the kit are high-quality RF ceramics of the C0G type (a.k.a. NP0 - near-zero temperature coefficient). Designed for the relay-switched programmable crystal replacement. It has three independent outputs with frequency range 3.5kHz to approx 300MHz, and can be optionally time and date, you can also choose to display GPS data (e.g. location, number of received satellites, etc). half and bottom half. The 4 parts are held together by 8 screws. The front and rear panels are drilled and silk-screen printed for the This GPS receiver module kit includes an extremely sensitive patch antenna, with factory pre-soldered Mediatek chipset RF module. It has three onboard LEDs for visual status indication, 3.3V regulator and power supply filtering, and 5V logic level conversion. It's easy to available for 16 bands 2200, 600, 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, 6, 4, 2m and 222MHz. The kit uses a high-quality double-sided PCB with silk-screen, solder-mask and through-hole plating. The capacitors supplied with the kit are high-quality RF ceramics of the C0G type with I2C (two-wire) interface. This kit (a.k.a. breakout board) contains pre-soldered Si5351A chip, 3.3V regulator, and I2C level is kit-built, it does not use an expensive commercial OCXO component. Construction of this kit is more difficult than the other kits, however it does not require any special techniques or equipment, as long as the construction steps are followed carefully.
