VHF rotor update

Last week I found the time to look at the VHF rotor.
This is the one mounted on the antenna deck that we moved to the west side of the building. I believe it had  been used by KB5EZ in his meteor-scatter research, so the expectation was that it might still be usable. I removed the 4 bolts that held the motor to the deck, and took it inside to clean it up a bit.

Antenna deck moved

After our last meeting, we learned that it would be a simple matter for us to ‘borrow‘ a forklift and a driver to move the antenna deck from behind the building.    So – we did that. The antenna deck is now beside the building to the west, and is Continue reading

TS-830 works again

TS-830 works again


The make operable activity on the HF station Friday afternoon was successful. There was no real disfunction to repair, but it was a good exercise in figuring out what we have, what works, what we need, etc… I spent most of the time looking for a probe, or even a cut-off BNC connector to use with the oscilloscope. Turns out – the cable between the mic stand and the radio can be plugged into the mic stand the right way and the wrong way. It has a symetrical pin config, but no mechanical key to ensure proper orientation. There is a tiny red dot on both the plug and the base connector. Once it was oriented properly – it worked. I had previously been able to go thru the TS-830 tune-up procedure on 20m, and the antenna was ready. Now with audio the radio can put out modulated RF. I made a brief contact with a station near Boulder Colorado for an audio check. Now that this station is operable, we need to establish our guidelines on it’s use – things such as training, logging, care-and-feeding of, etc… There is one more ‘trick’ to putting this station on-air, which I will share with those that get ‘flight-qualified’ on this rig… Still needs a good cleaning up but otherwise, it is now available for listening and general enjoyment.

HF station cleanup

From Friday, 2 Nov.2007 – I stopped by 4622 for lunch and cleaned up some around the HF station. Noticed some loose strands in the AC connector for the Linear Amp, and left a note that it needs a clean-up before it gets plugged back in. I swapped the desktop shelf with one from the south wall, seemed a bit sturdier. Also found a replacement coax jumper to go between the rig and the tuner, the old one had questionable connectors – I left the old one in the trash can.

Cleaned Cleared off the top of that file cabinet to the right of the desk, and moved the phone over there. Also pulled the desk out from the wall far enough to leave room behind for easier access. I might suggest that we disconnect coax at the back of each radio when we leave – even tho it is not lightnin season.

As we are into November, I also switched the thermostat over to heat, and set for ~ 60 degrees. All in all – things are looking better.

SiteVisit_20071009

On the previous web site built for the MSFC Amateur Radio Station, an early posting was with some pictures from a site visit in 2007. The idea was to set a benchmark, or a reference to look back upon for signs of progress. Here we have some of those pictures and text, as that previous web site is being replaced with this one.

Obviously nothing to get overly excited about, but many of us don’t have this kind of space available at home to build and test antennas. This location is also far from residential and industrial noise sources and is well suited for weak-signal and satellite operations.

We did some cleanup shortly after these pics were shot, and hope to post an update soon.
