Bombardier said: Hello,do you happen to have the modifications for the Texas Star DX1600 by chance? Thanks if you do,,much appreciated. Is this the information you are asking about ? MODIFICATIONS CW Transmitter To AMP Conversion Texas Star DX1200 - DX1600 Documentation Project...

Check capacitors C29 & C38 for being open or extremely out of specification. ( I recently had a Texas Star 500 with an open C38 capacitor that exhibited the symptons you are indicating). Also check capacitor C45 for open or out of specification. As you may know, the output combiner resistor...

Okay, I did just exactly the procedure above as stated by "Handy Andy". I had considered this before. I set the Ammeter up inline with the power supply as above, no RF..... First, I checked the current as it was since I set the gate voltage at 4 vdc previously. The current was 1.752 amps at...

Sounds like the internal amplifier board bias voltage is not being set correctly. I had this same issue until I got some guidance from Handy Andy on setting the amplifier board bias voltage correctly. Once done correctly, I haven't had any more internal amplifier blow the transistors.

This board was built and assembled by Tom , W8JI, ctr engineering........

Same here ....

I installed this upgrade filter board in my AL1500 two years ago. Designed and manufactured by the original designer of the Ameritron amplifiers. Ameritron Upgrade Boards Also see FC-220 3600 Volt for other applications Also see Step Start (Soft Start) Part Number F33-4500 This board is a...

I think the 2995DXCF is okay. The issues I have come across with the power amplifier is the finals bias current is usually set too high from the getgo. If the bias current is kept down to what the 520's are designed for the power section does pretty good. I got some help on that issue from Handy...

There you go. I didn't find the video, but it should help you.

Be sure all three resistors are good and at spec. Check the bias resistance of the input side before connecting to power. If bias resistance is not correct, do not connect power to amplifier.,

The Mercury does have the option of two big analog type meters. Touch the screen and the digital horizontal readouts convert to needle analog type meters.

Rich HAM ??????? Try a new Ameritron AL-1200 or AL-1500 amplifier. These tube amplifiers have been around for years. $6995.00

This is the new MERCURY LUX LDMOS Full Legal Limit Amplifier from KM3KM products. KM3KM is also the developer and manufacturer of the MERCURY IIIs amplifier and the Mercury AT antenna tuner. https://www.km3km.com/mercuryiiis-full-kit/

I do not find the HF bands to be formal. You can find formality on the bands if you look for it. It is there in places. I find the HF bands to be very informal. You can find a qso to get in on most anywhere. No formalities, black ties, or tuxedoes required. I get in with several different groups...

It just boils down to whatever helps a person study the information. I would study on hamstudy.org, then do the testing on hamexam.org.

The test questions on hamexam.org are set up exactly as taking an actual exam. Same formatting.

In addition to hamstudy.org , which is a very good study site, also take a look at hamexam.org. The test questions on hamexam.org are set up exactly as taking an actual exam.

I don't see anything in my previous post that I said anything about key up timing. I believe you just pulled that out of thin air.
