More info on this amp: TITAN 6m RF Amplifer

I recently bought this amp from a ham on EBay. He didn’t have any more info on it than ‘it works’. I would at least like to know what the typical RF output is (it has a pair of 6LQ6′s). I’ve not received it yet else I would have more hints. Let me know if you have a manual or a schematic:

UPDATE (March 26, 2011) – This amp is a 100watt Amplifier. The one I received is in fine shape and will be used with care and enthusiasm.

JT65 on HF, Pacificon 2010

You can work DX without a huge station using JT65 on HF

I have been enjoying making HF JT65 contacts as well as partaking in the JT65 Reverse Beacon network and reporting to PSKREPORTER.info the stations my rig picks-up.

Bought my Pacificon 2010 tickets, including the Antenna Seminar and the breakfast and dinner banquet. It will be nice to have it back in the Bay Area.

My A3S or A4S

So a few years ago I bought what I thought was a Cushcraft A3S Tri-band Yagi, used, on Eham.net classifieds. When I received it, I recall trying to set it up but being mystified since the traps were marked quite differently and the boom diameter was thicker.

Well I finally got around to figuring-out what I have, and here’s my best guess:

The whole thing is definitely a Cushcraft, but it’s an A3S driven-element and director, and the traps for and A3S reflector but the tip sections are longer and seem to be from the A4S. The boom is, as I said, from an A4S. The separate 10m element from the A4S is not present.

In essence, an A3S which can do more spacing.

When I bought this originally I was planning to take it out as just a two-element antenna for portable operations. But now I’m tempted to use this for contest season 2010.

Next step is to put it up on the crank-up tower and test-out gain and front-to-back. First, it seems I should try and get the director and especially the reflector (since it is a bit longer than an A3S reflector) resonant on their particular frequencies.

SO I’m thinking of using the driven-element center piece for the reflector and driven element to test their resonant frequency. I have a vague memory of these being 5% below the driven element for the reflector and 5% above the driven element for the director.
