Here is a pic of the front panel of the tuner. It has an active peak reading cross needle meter, an on/off switch for the meter and inductance turns counter meters, high/low and peak/avg meter switches, antenna switch, and the usual capacitors and inductor knobs.



Note that the inductor is a roller inductor for infinite tuning adjustments.

Here is the back side of the tuner:



You get two tuned antenna coax connectors, one additional direct, untuned antenna coax connector, balanced wire and long wire connectors, ground terminals, and the power source for the meter. Note that you can only use either the balanced line or wire connection; you can't use both.

Here is an inside pic of the tuner. The size of the capacitors, inductors, balun, and antenna switch is what enables the 3KW handling.



Here is a close-up shot of the silver plated roller inductor with my hand in it for perspective. Just below my index finger you can see the roller that provides the tap on the inductor.



The front side of the roller inductor has gears to work the inductor turns counter. This is a very simple, but effective design. The turns counter on this tuner isn't the most precise thing in the world but when you record your setting, it does give you a number that will get you pretty close so you can quickly recall your previous position when you change frequencies.



Here are the tuning capacitors. Again, my hand shows the size necessary to handle 3KW:



Here is the massive balun for the ladder line connection:



A nice big antenna switch:



And lastly, the meter circuit board:



You can see that this tuner also has the ability to use a 9v battery to power the meter. You don't get the lights when using the 9v battery, but you need to use either the wall wart or the battery to power the active peak reading meter.

I've owned this tuner for several years, certainly long enough to give a qualified opinion on it's effectiveness. I can happily say that I have never had any issues with it. The large roller inductor and tuning capacitors have enabled me to obtain pretty much a perfect match on anything I've tried. The inductor and capacitors aren't nearly as "smooth" to the touch as more expensive units from TenTec and others, but this tuner is also quite a bit less money.

The size of the cabinet and components used allows for plenty of air circulation when using high power levels. I have put over 2KW through this tuner (MARS stations have higher power level limits while operating on MARS frequencies) and never had one single issue.

My only real complaint about this tuner is the size of the meter. I would have liked to have seen a meter that is twice the size of the one provided. The built in meter will allow you to load up your antenna, but you cannot use it to obtain precise power level measurements. I almost always use an external large cross needle meter to adjust the tuner because I find the external one easier to read and I can obtain much more precise results.

The price of this tuner is about $600 new. If you don't need this much power handling capability, Ameritron and MFJ offer several others for less money. However, if you want a reliable, basic but effective tuner that will handle well above legal limit power, this one will certainly do the job for many years. ]]> moleculo http://www.worldwidedx.com/tuners-mics-meters-other-accessories/37095-ameritron-atr-30-3kw-legal-limit-antenna-tuner-review-pics.html power supply trouble! http://www.worldwidedx.com/tuners-mics-meters-other-accessories/36944-power-supply-trouble.html Tue, 03 Nov 2009 20:18:08 GMT I have an FT757HP power supply that I use on my rigs, and it has worked fine til now.

I hooked up my 7800r to it and it wouldnt come on or if it did it went right out, so I thought I had a connection problem. I got my VOM and started looking for the problem. What I found was that the supply was putting out 16-17 volts.:scared: The 7800 saw an overvoltage and went into protection mode.

I hooked the 7800 to another supply and it is fine. I have pulled the Yaesu supply out of line now, and replaced it with my pyramid supply. I wondered if anyone can help me diagnose it? I dont have a schematic, but I dont see any voltage adjustments.

Any Ideas??

Out of 22 reviews on Eham it came out with a perfect "5" out of 5 rating .

Can't wait to get it. I use it mostly for my Ft-757gx . I'll be relegated to my 101B which I also enjoy using.
So if anyone is contemplating a supply purchase this might be one to consider. It was around $82 . ]]> Sonwatcher http://www.worldwidedx.com/tuners-mics-meters-other-accessories/36909-ordered-new-supply.html pyramid model ps-52kx http://www.worldwidedx.com/tuners-mics-meters-other-accessories/36832-pyramid-model-ps-52kx.html Wed, 28 Oct 2009 21:35:55 GMT can anyone help me to get a sch. on a pryamid model ps-52kx ? thanks for any help..looking for value of ds. can anyone help me to get a sch. on a pryamid model ps-52kx ? thanks for any help..looking for value of ds. ]]> donemad http://www.worldwidedx.com/tuners-mics-meters-other-accessories/36832-pyramid-model-ps-52kx.html turner + 3 wiring http://www.worldwidedx.com/tuners-mics-meters-other-accessories/36774-turner-3-wiring.html Sat, 24 Oct 2009 16:30:24 GMT I have saw the wiring for a Turner + 3 to a Cobra 25.

When I wire it up as stated and I plug it in the radio I get
a loud hum and the needle pegs to the right.
Here is the way I wired it up.

Any suggestions?
It's not the radio cause I tried it on my other Cobra 25 which is brand new.

Here is the info from Palstar: Image:... Palstar is shipping a new speaker geared for radio communications: SP30H is the model number. Here is the info from Palstar:



New from Palstar: the SP30H, the ultimate communications speaker. The "H" stands for both high quality and high power, because the SP30H can handle a maximum 25 Watts RMS of audio power.

Measuring 11" wide X 8-1/4" high X 10" deep, the handsome wood cabinet is specially made for Palstar by a high-end custom cabinet shop, and features a beautiful stained and varnished birchwood veneer finish.

The 6-1/2" speaker is optimized for 55Hz to 8KHz, perfect for communications intelligibility, and features a massive 11.6 oz magnet. The cabinet interior is lined with acoustic dampening material.

I talked to a local the other night on 75 meters who alerted me to this speaker. He bought it and was giving it RAVE reviews. He said that he has never had a speaker hooked up to any of his HF rigs that sounded that good, that clear, just perfect for ham radio. It's not a small unit, so you'll have to find some room on your desk for it. However, the way this guy raved about it, it's definitely worth considering.

If anyone decides to pick one up and try it, make sure and give us a report! ]]> moleculo http://www.worldwidedx.com/tuners-mics-meters-other-accessories/36750-new-palstar-sp30h-communications-speaker.html
