Description

DESCRIPTION :

HBRCW5 Shortwave Radio Transmitter Receiver

100% New and High Quality
Single channel Xtal based CW transceiver

This is a very small volume of simple 40 meter band micro-power amplitude telegraph transceiver.

The new “HBRCW5” has the following characteristics:

1. The output power is raised to 3W, power output using an tested with proper transistor, it has a strong remote communication capabilities, enhance the CW 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. This HBRCW5 is based on forty-9er, then upgraded.This transceiver was used with a QRP antenna and cable, so this set is ready to use.

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 3904, 3904 also as the transmission key, and then send the LPF after the antenna is connected. There sidetone launch.

FAQ:

Q: How far can be transmitted?
HF communication and propagation environment, antenna, equipment, operating level, and several other factors, alone device more difficult to guarantee a specific distance. Our suites are all classic models, a lot of people at home and abroad is already in use, the restaurant also has a client transmission performance is very good, the basic premise is that good performance antenna!

Q: telegraph can talk it?
CW transceiver can not talk, only supports the SSB or FM modulation, such as a machine before they can talk, can only use the key transceiver transmitter and headphones receive messages.

Q: key need to buy it?
For just beginners, amateur production expensive in DIY, do not recommend that you purchase an expensive key recommended homemade, find old mouse + MP3 headset line their own modified one.

Q: What kind of antenna?
Recommended “dipole” or “inverted V antenna”, you can query “shortwave dipole antenna” for more information.

Package Included:

1x New HBRCW5 assembled include plastic enclosure
1X QRP Antenna include Balun, plastic enclosure and 18m Ant Cable (40m Band)
2X New Travel Case
