Yep, it is true ........ I personally know that to be a fact !

I usually like repairing Texas star amplifiers. They are relatively easy amps to repair. I have repaired a lot of them. But I do not like to repair, fix other folks hacked up amps that made a mess inside.

Probably still doing the repairs. But they will not accept/repair a basket case that has been hacked up or modified.

The amp bias is not set by gate voltage, it should be set by current draw....... The mosfet finals can be "popped" very easily......

I still have an "original" , new in the box SPT 500 that has never been out of the box. I think it is about mid '80's model...... Interested ?

Correct. To take an actual official amateur test online, you have to find a local VEC and coordinate with him. You will be required to set up multiple cameras from various angles in the room with you. This is for the VEC's to be able to observe you and your surrounding testing environment while...

And 4 Toshiba 2SC2879 transistors will output that much power with much less voltage and much less RF drive...... and will not be stressed like the HG's in the post above...... Just saying .......

468/27.205 = 17.2027 ft. /2 = 8.601 ft per leg ....... 468 divided by frequency = total dipole length total dipole length divided by 2 = length per leg

In my opinion, the best study websites available with plenty of practice exams. No fee required, no membership required. Use them as much as you need to. My wife and I both used these two sites exclusively to study and practice test for all levels of our amateur license, from Technician to Extra...

Don't have any "pills" in any of my amplifiers ........ I use "transistors", different types .......

You're on your own with your bridge .......

I have several Texas Star DX500-HDV amplifiers. All were purchased new by me over the last few years. I have upgraded the power wires and installed new, from my personal stock, original Toshiba 2SC2879 transistors in all of them. $1,100 (original Toshiba transistors are $200+ each if you can...

8.5' long for each wire, put up in an inverted "V" formation with a minimum 90* included angle at the coax connector.......

Looking forward to seeing photos.......

Looks very good also. The 20' I-beam I used is what I already had on hand out here on the ranch. Having 15' above ground just reduces the load on the winch, and the stress on the tower. What you are doing will probably work just as good as what I did. But how are you going to tilt the tower...

Tilted over, I haven't taken photos yet, but I have also installed a tilt plate at the top of the mast and the antenna stays in the horizontal position now all the way down to the ground. I use these two antennas for 10 meters and 11 meters. I also have an OCF wire off the side of the tower at...

the I-beam is 20' long, with 5' in the concrete, and 15' up the side of the tower.

It doesn't require a 50 amp power supply to operate, but performance would likely be limited if using less than a 70 amp power supply.

Well, it may have been designed for 13.8 volts, but it is a mobile amplifier. Very rarely does a mobile alternator electrical system operate at 13.8v. Most will operate at 14v to 14.5v...... So operating this amplifier at 14v on a power supply is perfectly fine and it will last for years and...
