Tube Tester and Filament Burn In Jig - Here`s my answer to cooking the tubes for days and then testing them before inserting them in an amp. Note - I have learned an important lesson with this jig. The filament alone heats the entire bottom of this tube and.... -
Any NPN transistor can be used. The author used a 2N3904, but a 2N2222A should work just as well. A good, low noise transistor would be even better. Some radios only have three connections to their ferrite bar antenna: the antenna connection to the tuning.... -
This project and your efforts will provide you with a 0. 55 3 watt input to easily 10 watt output. The two linear amplifiers are ment for use with QRP SSB/CW/FM/AM transmitters on the amateur bands 15 and 17 meters can be powered from a 12 volt DC supply..... -
Here`s RF Power Amplifier for QRP with low cost. This circuit is a broadband one from 1. 8 to 30 MHz, so it is "no-tune" and you need only to regulate the quiescent current bias multiturn trimmer of each Mosfets couple. This means also low efficiency (for a.... -
An RF power amplifier is a type of electronic amplifier which is utilised to convert a low-power radio-frequency signal into a larger signal of significant power, usually for driving the antenna of a transmitter. It is usually optimized to have high.... -
