DIY KITS HAM RADIO 40M CW QRP TRANSCEIVER 7.023-7.026 MHz
This board not assembled, need solder yourself
This suite is the classic "PIXIE" (" shoes ") low power transceiver.This is a very small volume of simple 40 meters micropower continuous cable transceiver, use the 9 v battery power supply.The earliest by this circuit design abroad, its frequency stability, poor selectivity, but receives the effect is good, code readability is stronger, is one of the most primary radio enthusiasts entry choice!
Note: this is bulk, not a finished product.
Features:
Power supply: DC 9v - 12v
Antenna: 50 ohms, is not balanced,7MHZ band, standing wave ratio below 1.8
Receive the static current: 10ma @ 9 v
Transmission power: 0.8W @ 9 v, 1.2W @ 12 v
Frequency range: 7.023 MHz launch, receive 7.023-7.026 MHz (7.023 MHz crystals)
Stray (harmonic) inhibition: - 20 db
Working pattern: CW
In the field of amateur radio, usually no more than 5W is known as a low-power communications, or QRP QRP communication is an important branch of amateur radio.
Many QRP communication enthusiasts keen on homemade QRP equipment.
Classic kit, hope you like.
Faq:
Q: communication distance can be far?
A: shortwave communication distance depends largely on the antenna selection, and the use of small power station must choose good weather
Many master, using the classic radio had hundreds of kilometers of achievement. Radio component of this shop are through the detection apparatus, device
A purchase large quantities so can guarantee authentic, key device also after sampling, the output power of a good. So as long as you
The antenna resonates well, there will be a good communication distance.
Q: beginners should start from where?
A: the first step: the correct welding welding of finished products.
The second step: listening, practice to understand the air code,
The third step: the practice of generating code technology own,
The fourth step: make the antenna, the best conditions to buy two sets of spontaneous self test,
The fifth step: and the rest of the world.
Q: the telegraph can talk?
The A:CW transceiver can't talk, only supports SSB or FM modulation machine can intercom transceiver can be used.
Key and earphone receiving message.
Q: suite of difficult assembly?
A: a necessary premise is can recognize device, welding, induction machine without debugging, as long as careful according to kit instructions assembly can become
Work. If the new welding error condition, built the first not to handle, please contact customer service, can obtain the corresponding technology Guide.
Q: the use of antenna what kind?
A: this shop will provide a few simple antenna tutorial.
