HAM RADIO 40M CW Shortwave QRP Pixie Transmitter Receiver 7.023MHz-7.026MHz DIY
Shortwave Transmitter(Kits)
This kit is a classic low-power transceivers.
This is a very small volume of simple 40 meter band micro-power amplitude telegraph transceiver uses a
9V square battery.
The reception is good, highly readable code, is the entry of the most junior amateur radio choice!
Technical parameters:
Power supply: DC 9V-14V
Antenna: 50 ohm, unbalanced
Receive quiescent current: 10mA @ 9V
Transmit power: 0.8W @ 9V, 1.2W @ 12V
Frequency range: launch 7.023MHz, receive 7.023-7.026MHz (7.023MHz crystal)
Mode: CW
Shell selection and installation:
Beautiful metal case not only for item considerably, and can effectively shield nearby interference.
There are many optional shell,
for example, metal cans, aluminum boxes, medical elongated aluminum box andso on.
Select the box in time topay attention as easy to open, because the battery ran out and need replacing.
Recommendations:
The confidential achieve better results,
set the antenna performance can not be less than the full length of the horizontal half-wave dipole antenna,
in conjunction with the use of Simple Barron, antennas should be kept away from sources of interference,
such as fluorescent lights, computer monitors, switching power supplies
and other equipment as much as possible with the coaxial cable as feeders to reduce possible interference
received,as a small selection of the broadcast interference morning or late at night listening to get the best results listen to SSB and CW signals signal.
The default shipping for spare parts kit.

This QRP Pixie Kit not fished,is diy kit,suite welding need electronic technology basis,
please bring your own multimeter and electric iron tool.
This suite is PIXIE low power transceiver classic, recommend the use of Google search Pixie QRP,
will see a lot of English website of its introduction.
This circuit is most early by the foreign design,
is the most Junior Amateur Radio choice! Kit using amateur radio electric door band 7.023MHz,
the shop improved circuit, did receive the same frequency.
Kit consists of the modifications to the original design circuit PIXIE,
now launch of the vibration frequency is fixed at 7.023MHz,
when receiving the vibration frequency is 7.023-7.026MHz adjustable,
can easily beat frequency, greatly facilitate the primary lovers enjoy radio fun!
"Pixie QRP" emission power: 0.2W (12V supply),
PCB Size: 5cm * 5cm

Shortwave Transmitter&Receiver(Red)
This is a very small volume of simple 40 meter band micro-power amplitude telegraph transceiver.
The new "Forty-9er" kit has the following characteristics:
1, the output power is raised to 3W, power output using an American ring, it has a strong remote communication capabilities, enhance the Forty-9er practicality!
2, increasing the side tone circuit, so that when you operate the transmitter, the headset can also listen to the keying signal, side tone circuit using an audio sine wave generator, the effect was significantly better than the ordinary sense of hearing frogs square wave generator.
3, when the vibration frequency of the kit launch fixed 7.023MHz, when receiving the vibration frequency is 7.023-7.026MHz. PCB size is 6cm * 6cm.
4, the kit can be easily placed in the PCB 65mm * 35mm * 100mm standard aluminum shell, the kit does not include this housing. If there is a need to contact me!
The main index:
Power: 12V
Receive quiescent current: 23mA @ 12V
Emission current: 450mA @ 12V
Transmit power: 3W @ 12V
Frequency range: the vibration emission 7.023MHz, receive local oscillator 7.023-7.026MHz
Transceiver Distance: 100-300 km.
Mode: CW
Circuit Schematics:
Receiving section for a typical straight LM386 NE602 plus variable receiver.
Emitting portion utilizes the oscillation circuit NE602, and then to do the buffer amplifier 8050, 8050 also as the transmission key, the last stage is a class C amplifier D882, and then send the LPF after the antenna is connected. There sidetone launch.
