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.

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.

Yes sir, I am aware of what you are referring to. The menu setting in the radio will delay RF output for a time period, ( all be it very short time period), after the PTT SEND signal is energized.

It is best to go into the 7300 menu and increase the RF "tail" issue to the maximum delay time. It will help to minimize the RF output from the radio into the amp, before the amp is fully keyed up and ready for RF. I have been operating two 7300's for 6 years with several different types /...

I just repaired an ICOM PW1 amplifier for a fellow amatuer radio operator. He uses it with his ICOM 7300 and 7610 transceivers. Fortunately, it was not a power supply issue. Needless to say he was extremely pleased to get it back into operation. A first for me.

Look at the copywrited date at the bottom. That is not the official updated CBTricks website. It is an older cloned version. It may be safe, but it is not the official website.

The gap is like a spark plug gap, hence the specified gap. I am not sure , but I think it acts as some kind of safety or protection device. "There is a voltage limiting gap built into my amplifier. This gap is designed to be the point at which any arcing will occur (harmlessly) if the tank...

Here is a good writeup guide. Not by me, but I'm in agreement. Hi Dan here in Conway S.C. AKA TURBO. Here is a cheat sheet i made up...Use this first. No receive: when the power is on, does the light behind the meter turn on? if the meter light turns on without being keyed up, then the...

Power supply voltage to both ends of the output transformers, and to the collectors of both power transistors. If voltage is present, then your initial statement of no power to rear board is inaccurate. Hence, my question of "voltage power or RF power".
