I've owned an AT5K.  Good tuner but at half the price the ATR-30 would be my choice (I own 2).  Also own an MFJ-998, good tuner, may be a bit complicated, had to replace an intermittent power switch, but this tuner will take 800 watts of RTTTY for the short periods that I've used that mode for tune up purposes.

For what you plan on doing with it, I can strongly recommend an ATR-30.

I'm leaning towards that direction.  I was reading the spec sheets on the Palstar AT4K & AT5K today and they're all over the place regarding what continuous power they can run.

Both of them use the same 10ga roller inductor, which I really don't feel is that much of an upgrade over the AT2K with its 12ga inductor.  

My only concern with the MFJ aside from all the parts arriving in VK first go (if I have to fix any whoopsies thats ok), is how well the roller inductor works.

I've heard it doesn't feel as nice as the Palstars to use, but at the end of the day its Edge Wound and considerably bigger than the inductors in ANY of the Palstars.

And yeah, its really cheap too.

I'll put down 1 vote for the ATR-30.

I have both an ATR-30 and an AT2KD.

The Ameritron ATR-30 is, from tests I've read, more efficient on lower bands. It also has a wider range.

On the other hand the AT2KD is very simple and easy to use with the differential capacitors. It also operates
really smoothly.

I have purchased several tuners used. They are often for sale at good prices. The ATR-30 I bought did not have a smooth-
turning inductor. I took the inductor and drive apart and made some alignment adjustments and it now works very well.

jarrod look at the inverted L's mine has made a big difference to my station on the low bands my block is only 700 sq meters so the same and its not set up perfectly i fact most people he would shudder but it works Smiley


Come winter it might be a possibility Steve.  One of the supports for my Dipole could easily be turned into a transmitting vertical.  At the moment it is 6.5M 50mm Aluminium tube, but I plan on extending it soon to 10M+ as the tube is rock solid in the wind.

The beauty is, the back fence backs onto a council park... so all I have to do is wait for the ground to get wet and I can bury one heck of a radial field  Grin Grin

Yeah well, "change" is hard down here.  Our national body is basically the swamp that your president keeps talking about sigh.

I saw that when I spent most of 83 down there leading a team of engineers and techs to install a nationwide broadband over CATV hardline network throughout the continent plus several islands. It was for the social welfare types and Australia Telcom was a royal PITA until someone paid them off as suddenly things went easy.

Great country, women and beer BUT Vegemite sucks Grin Grin

It works, the CW decode is better than most.

Can't be much business in this? Maybe that's why the other guy went out of business?

He went out of business because he retired from everything and I think moved to Florida. He had more work than he could do.

That fits my experience, solder is lossy at microwave, but really should not be any kind of issues in a HF amp as long as it it done correctly.

A company I worked for used solder paste to around 12 gHz and gold wire bonding above that.
