Jun 29, 2015 · A balanced tuner. The balanced tuner must convert the unbalanced antenna input/output of the antenna to a balanced 50 ohms and then drive it through an impedance transforming network to the antenna system's impedance at the end of the open wire feeder. The following article was originally posted on my other radio blog, the SWLing Post.. Earlier this year I published what I called an "initial" review of the CommRadio CTX-10 QRP transceiver, promising an eventual final review. The reason for this is that I sensed there were important CTX-10 updates on the horizon, and I wanted to re-evaluate the rig once the upgrades had been implemented ...This is the manual page for _other. Here you will find instruction manuals, service manuals, user guides schematic, brochures etc. The new 550 kW 9330 kHz WBCQ transmitter is already causing overloading issues for many SWLs. One solution is to built a notch filter. This can easily be done using a Tee adapter and a piece of coax cut to 1/4 of the wavelength (taking into account the velocity factor of the coax). These preliminary pictures show my QRO ATU / Dummy Load / Power meter intended to be capable of handling the full 400W UK Legal maximum power at HF ( 30MHz). The project is basically a scaled up version of my QRP ATU manufactured in 1994. ATU (Antenna Tuning Unit) The ZM-2 ATI-J is unique in that it does not need a tapped coil to accomplish an antenna match. Basically, a Z Match tunes 2 frequency ranges 3.5 to 11 mhz, and 12 to 30 mhz at the same time. This is approximate for this version, but it will be able to match most antennas in this range to a I to I SWR.Narrow Your Results. Match your transmitter, transceiver or amplifier to virtually any antenna or antenna feedline—balanced, unbalanced, or single-wire! We have antenna tuners that offer superior, wide range impedance-matching capabilities when compared to tuners built into transceivers--and with more efficient power transfer. Hi I am looking into getting an auto-tuner and quite like the look of the LDG range. So what do people recommend. Want it to work with my current radios:- IC-746 and IC-706 mk11 and QRP. · MIZUHO MX21S QRP Transceiver · HF SSB QRP Transceiver - YD1JJJ · 40m CW QRP Transceiver - NT7S · Long Range FM Cordless Telephone · 3.5 MHz 5W CW Transceiver - JF1OZL · 14 MHz 10W SSB Transceiver - JF1OZL · 21 MHz QRP SSB Transceiver - JF1OZL ATU flexibility. In my initial review, I noted that the CTX-10 ATU needed near-resonant antennas for the ATU to make a strong 1:1 match. Indeed, a number of times I actually used a near-resonant antenna in the field––the EFT Trail-Friendly, for example––and the ATU couldn’t get below a 3:1 match. M0JMO Rating: 2010-03-16; Works Great for QRP /P Time Owned: 0 to 3 months. I needed a small, light ATU for portable use with my new FT-817.
