The kit can be through the T network resonant antenna, to make the radio work normally. Change SWR, corrections due to external reasons not tuned antenna. Can be used as a bandpass filter, Reduce the harmonic in the transmitter, to reduce out of band cross modulation and interference when receiving.
My homebrew antenna tuner is capable of handling 100 watts if I need to use it with my IC-7200 XCVR. I will publish the results of my experimental tuner on this page as I progress through variations of it.
The MFJ-9232 Mini Loop Tuner TM is a small, versatile, high-efficiency device that turns any wire loop into a high-efficiency multi-band transmitting antenna system. It is designed for 50-ohm use at QRP-power input on all modes. Two items are required: • MFJ-9232 Mini Loop Tuner TM (Shown in Figure 1) • Wire Loop(s) (not included) Figure 1 ...
QRP Manual DIY Antenna Tuner Kit 1 -30Mhz. Version 2.1 - 24/5/2021. This document was re-written and added to by Bob Fryer - VK1ERF Additional review by Rod Channon – VK1CBR. Attribution. I feel it is only fair that attribution should always be given where original published work has been used for the basis of a project or design.
These include a receive/transmit switch to transfer the 12 volt power and antenna between the transmitter and the receiver described in Chapter 7. Another addition was a "spot" switch to make it easier to find the transmitter frequency on the receiver dial.
The switches and lights on the lower left are the main power switch and the transmit/ receive switches. There are also LED lights to indicate which switches are active. The large red button is a fispotfl switch. With the spot switch engaged, the QRP oscillator may be tuned to another station without actually transmitting.
