eBay (12) 28.224 MHz Beacon QRP Crystal Oscillators 1223 Most purchases qualify for a ** Combined Shipping Discount ** Fast eMail Fast Shipping Guaranteed Good-on-Arrival (12) 28.224 MHz QRP Oscillators 10-Meter QRP Beacon Transmitters Manufactured by CARDINAL P/N CTH11001-28.224 Fully shielded circuit Price is for (12) pcs (Check our store for other quantities and discounts.) Build your own 10-Meter Beacon with this QRP transmitter. With 5 Volts applied, the output power is approximately 35~40 mW into a capacitively coupled 50 ohm load. The 28.224 MHz (±100 ppm) nominal frequency is near the center of the 10-Meter beacon sub-band. The output is a TTL compatible square wave and a LPF (low pass filter) is recommended to remove harmonic content. [LPF(s) are NOT included.] The four-pin footprint matches the corner pins of a standard DIP14 package. Pin 1 (squared corner) is not used. Pin 7, ground, is internally connected to the metal can. Datasheet: https://linearparts.com/documents/CTH11001_28_224.pdf Application Ideas Here are a few simple schematics for your experiments. Note: This listing is for the oscillators only. The other parts shown are NOT included. Check our store for the NE555 ICs and the 0.33 µH coils. The output (pin 8) is a TTL compatible square wave producing approx. 35~40 milliwatts into a 50 ohm load with 5 volts applied. At 5 volts, current at pin 14 measured 17 mA unloaded and 26 mA with a 50 ohm load. We tested one of these oscillators at 9 Volts for 4 hours. The frequency shifted <100 Hz from the 5 volt state while the RF output voltage doubled (approximately quadrupling the power) and remained stable throughout the test. The can was warm, but not hot to the touch. Nine volts greatly exceeds the spec's 5.5 volt max so there is NO guarantee any will work at all at 9 volts or for how long. At 9 volts input, current measured 50 mA unloaded and 73 mA with a 50 ohm load. We also tested it at 12 volts. At 12 volts, it only worked for a few seconds and then stopped. The current skyrocketed and permanent damage will occur if left at 12 volts (or perhaps less) too long. We immediately removed power and it appeared to recover with 9 volts applied.
