Gene Marcus, W3PM GM4YRE. There is the Frogs version which has more output and uses an extra crystal in the receiver path to help filter out unwanted signals. Pretty minor, but I ran a WSPR beacon on 80M for a couple years. Adding 20 meters to the QRP Labs Ultimate3 WSPR TX : I moved my little QRP Labs Ultimate3 WSPR transmitter from 30 meters to 20 meters, which involved building the kit for the 20 meter low pass filter. Below is a map of where I got on 200 mW. Works on any band from 2200m to 2m with an option to operate on up to 6 bands. stuff that i do and things that i make. all on our home made 3 element yagi. The following notes show the design and construction of a Broadband HF Vertical antenna which does not require a tuner, and which is capable of providing moderate performance on all bands from 7MHz to 28MHz (reduced performance from 3. This is critical for if the transmitter is over driving it will result in a lot of adjacent channel interference and possibly damage to the transmitter. They are available in portable, car, and high altitude balloon versions, and are pre-configured with your amateur radio callsign. I'll have details coming in the near future on the setup, but it's a super cheap, homebrewed transmitter with a crystal and couple of 2N2222 transistors to generate the radio signal, and it's fed the CW beacon by an Arduino Nano. See below for the long list of features! This is a kit of parts that you assemble yourself. 8-bit computer - output register & bus; 8-bit breadboard computer - eeprom programmer. When I asked what he was going to use it for, he said that he was making a WSPR transmitter with a Raspberry Pi, and the balun was for the dipole he built for it. This configuration uses a Raspberry Pi Zero as WSPR transmitter for 20m and 40m. Encouraged by a post on a forum that I visit, I decided to have a go with WSPR (Weak Signal Propagation Reporter) whilst I was working in the shack yesterday. The WSPR-TX_LP1 is a standalone all band WSPR transmitter with built in GPS for the radio amateur experimenter. Raspberry Pi bareback LF/MF/HF/VHF WSPR transmitter Makes a very simple WSPR beacon from your RasberryPi by connecting GPIO port to Antenna (and LPF), operates on LF, MF, HF and VHF bands from 0 to 250 MHz. Standalone Multiband WSPR beacon transmitter (MEPT) By Guido, PE1NNZ SPECIFICATIONS Modulation: 4-FSK, WSPR broadcast (Layland-Lushbaugh polynomials for a K=32, r=1/2 convolutional code). Simultaneously (or, at least, at different points in its 10 minute operating cycle) the Arduino Beacon produces WSPR messages and these were decoded and reported automatically by reporting stations all over the place. 1 | P a g e White Paper WSPR by Joe Taylor, K1JT for transmit and receive antenna comparison by Larry Plummer, W6LVP January 10, 2017 EZNEC and other analytical tools are great for initial antenna design. It is available in 3 different Amateur Radio HF bands as well as 2 AM/FM broadcast frequencies. What is OpenBeacon?

The case is for a specific variant of the Pixie, available from quite a number of different China sources. For SSTV, the generated signal is a frequency modulated tone causing a normal SSB transmitter to work hard, exceeding its nominal duty cycle. This Ham radio project describes using an ARDUINO (SS MICRO) and an AD9850, plus a handful of other parts to build a 5volt standalone WSPR transmitter. Whilst they are exceptional value and using them as SDR dongles is a brilliant piece of hacking I just haven't had really utilised them since I have my FUNCube Dongles, both the HF capable PRO+ and the older PRO version. W6LVP amplified receive-only magnetic loop antenna (boy is that mouthful): The W6LVP mag loop is a complete receive antenna system delivering top-of-the-line performance to amateur radio operators and SWLs. This is a case for a super inexpensive amateur radio 40m transceiver, the Pixie. This project aims to push the limits of how far away a Pi transmitter can be heard. jack is a 2 conductor type, the "shell" side could be grounded (with the jack's "tip" connected to your long-wire antenna). For WSPR the exact transmit frequency needs to be very precise. As the name and the picture indicates it is very small and. WSPR is an excellent choice for testing out a freshly built transceiver since it gives immediate feedback through Internet if anyone out there receives my signals. While I was fiddling with this mode with Ian, we discovered a very simple way of demodulating this digital mode using the cheap DVB-T/FM (rtlsdr) dongles. It's a 6 band transceiver covering 3. A qrp cw transceiver for either 30m or 40m. Some Updates (03/11/15): There is a new program up that I wrote where you only need the filename (NOT THE PATH). Check it out here. It is available for 80, 60, 40, 30, 20 or 17m bands.

Airspy, a High Quality Approach to Software-Defined Radio. Thus, through a Drake MN-2700 which allowed peaking full 1W output into a DX88 vertical, the results were great; topping the evening with a bounce back to the East Coast to. This project provides a simple means of generating an audio WSPR signal using either an Arduino Nano or Arduino Uno to drive a SSB transmitter for mobile or portable WSPR beaconing. Connecting a wide band antenna such as a discone to the input often results in a spectrum full of noise which swamps the target signal. I had the pleasure of making many long distance contacts including Anchorage in Alaska from our base station setup in regional SE QLD. Tags HF , LF , MF , transmitter , VHF , WSPR beacon.
