Note that this modification is actually the way Dentron did it in later production models of this tuner. Just disconnect the wire to the capacitor.) This increases the total capacitance available, making for better range of matching, especially on 160 meters. (IMPORTANT: LEAVE THE EXISTING WIRE FROM THE COIL SWITCH ATTACHED TO THE GROUND LUG. Sorry if this photo is confusing, but there is not much room in this compact tuner. This new wire does not attach to the bottom of the coil, it just is a splice, up in the air over the lug that supports the coil. Thanks to W4DEX for the info:ĭisconnect the wire shown by the pointer (wooden barbecue skewer) from the ground lug near the front panel and attach it so that both of the stators (stationary plates) on the left hand capacitor are connected together. I modified the one I had to match the later version of schematics he shows. This does not match the schematics on the website listed below. Later versions of the Dentron unit shown here may be built for more power.Īs I received this tuner, the left hand capacitor was wired as a sort of "voltage divider" similar to what is used on the output of the Johnson Matchbox JR. Some similarities to the Johnson Matchbox JR 275 watt tuner can be drawn, and perhaps I am being too conservative in my speculation on power rating. MFJ likely would have advertised this tuner as a 300 Watt unit.

The 160 10 AT, when properly adjusted, will tune out load reactance, and transform the load impedance to 50 - 70 ohms. DENTRON MT-3000A TUNER MODS BY W1AN The Dentron MT-3000A is an excellent tuner that has been around for many years.

This manual tuner extends the range to work with an end fed wire, G5RV, open wire fed doublet, or the band edges of a standard 80 meter dipole. DenTron 160 -10 Super Tuner and 3 kw Models The Den Tron 160 - 10 AT Antenna Tuner (Transmatch), will couple a 160 - 10 meter Transmitter to almost any type antenna system. The internal tuner in the FT-450 will not match more than a 3:1.

Damage to the plastic coil may result with full duty cycle full carrier 100 Watt AM. But I doubt it will handle a 100 Watt AM rig like the DX-100. If he inherits my DX-40, it will likely be fine with that, or a barefoot DX-60 too. The the mechnical connection between the variable capacitor shaft and the knob must be insulated and isolated. I purchased this nice little 100 Watt CW or SSB PEP class antenna tuner at a swap meet as a gift to a friend, to use with his Yaesu FT-450.
