I had another friend assume he could repair his Texas Star DX500V himself......
Simple repair, Power button light bulb burned out.....
He turned a simple fix into a somewhat major repair.
He did not disconnect the DC voltage supply before he started sticking metal things inside......
Yep...

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.
Went with a new NI4L OCF 7 Band Dipole Antenna this past weekend.
Had to do some tree trimming because I wanted the antenna to be completely in the clear.
And It is now removed from any close proximity to any metal objects and the very large metal roof on the house.
I'm gonna put this antenna up today and give it a try.
It was given to me by another HAM because he moved and did not have the space to install in his new location.
Inverted V installation with the apex at about 40' and the ends at about 15' ....... tied off with Mastrant rope.
We'll see.
I do...
Well heck, I am back to considering selling my Ranger RCI 2995DXCF radio.
It is a very good radio, good audio, looks good (like brand new).
I purchased it new, several years ago. About 2016 I think. I would have to look at my original documents.
I just don't operate it as much as I use to.
I am...
I have been working on my radio because the amplifier board was not working properly.
I replaced all four amplifier mosfets and the 2 (two), driver and a single final.
I made no initial adjustments.
When I applied power, at first all seemed okay. I keyed the mic and immediately things went...
I have a good friend who purchased this radio maybe 2 months ago.
The only modifications done to it is the frequency conversion to open up 11 meters.
He still has the original box.
He has since purchased a new base station radio and is interested in selling the 98VHP.
He is asking $450 plus...
I just kind of wonder what an original, BRAND NEW in the box, Hygain Super Penetrator 500 Antenna would be worth to someone nowadays ........
I am just wondering because I still have one in the original box stored in my attic storage space.
Never been assembled and used .....
Well, I went and picked up another brand new Texas Star Sweet Sixteen 1600 amplifier, that I don't really need. But the costs of these 1600's are really starting to go up and up. I just got it before the big price increases.
It has the Toshiba 2SC2879 transistors in it.
But I am pretty sure they...

The strangest thing happened the other night when using my Ameritron AL-1500 amplifier.
While tuning the amp for one of the HF bands, I happened to be glancing at the top of the cabinet. I heard a light sizzling sound at the same time I saw some dim lighting come from the outlet vent on top...
I was reading a thread this morning about Icom 7300 power "mods" and made a post about my experiences.
Did something happen I didn't see ?
Did things get rowdy or something ?
Just wondering
I have a brand new, out of the box, Texas Star Sweet Sixteen on my bench.
1).... Upgrade power wire, positive and negative, to the board and to the output transformers
2).... Upgrade the 4 filter capacitors from 1000uf 16V to 3300uf 25V
3).... Move the fan thermal switch from the PC board to...
Palomar Magnum 6000 Original Gray Face.......
I need schematic for this amplifier.
Some one has removed the RF sensing keying circuit .....
I could also use some detailed photos showing location of keying circuit components.
Last week I ordered an upgrade HV filter board from Tom - W8JI - ctrengineeringinc.com .....
I received it yesterday and installed it today.
Piece of mind for reliability goes a long way .......
A friend sent me his Sweet Sixteen last week. I finally got to it yesterday.
His information to me is that it keeps knocking out finals as soon as he keys it up.
It is an older model, still has the glass capacitors in it. I'll bring everything up to date.
I'll start at the beginning and just...
Have an old original Moonraker 4 looking for a new home.
All parts are there. All 4 hubs are good, no cracks.
Needs some cleaning up and TLC. Needs all new hardware.
It is about 35 years old and was still up and operating until last December 2018 when we took it down.
I have another Texas Star DX 500V amplifier in from a friend to take a look at. He purchased it new about 2 months ago.
It is experiencing high VSWR's on any antenna, but almost flat on a dummy load. This information is according to an experienced tech who has already had it.
He asked me to take...
