FT-101E Project: The tune-up

So I have been playing with the FT-101E a little bit here and there and did finally check the output by simply connecting a dummy load and following the factory tune-up procedure.

With a random wire and an antenna tuner, I am able to get 80′ of 26ga wire down to an SWR of 1:1.3 or so which is not too bad! The only problem is that I have to operate it against the side of my building (for the moment) which appears to attenuate much of what I hoped to receive, and as the saying goes: “you can’t work what you can’t hear”.

I am not entirely sure if it is a receiver issue or an antenna issue at this point. The old machine may have detector issues, or a faulty noise blanker (which when removed effectively cripples the radio). I would love to borrow an HF rig to test my set-up with. Perhaps I will just wait to buy a “real” daily-use machine and test with that – the only issue being cost. In a mere five weeks (plus four days), Julie and I are getting married so hobby associated spending has been at a minimum.

Some day I’ll have my own station … 🙂

Server crash …

Hi all,

Still working away on my temporary VPS solutions while I source a new 1U server to replace my old system. The old unit finally died after 11+ years of continuous service.

I expect it will be a couple of weeks until I can ship a stress-tested server to my data center in Tampa. Until that time, we will experience some minor glitches here and there.

More to follow …

(update): Mar 29 2011

  • Purchased 1U server via web-site from PCCyber – was told should hear back within 48 hours.
  • Waited one week and still did not hear back from PCCyber.
  • Called them and the web-sales goon indicated that he forgot to call me to let me know the server was on back-order.
  • Canceled order with incompetent company (history of troubles with them)
  • Purchased the same equipment from PC-Canada. Should be at my door in a day or two (Ie. April Fool’s).

So, all should be back to “normal” soon – not that anyone would realize the difference I am sure (being that this is all behind the scenes stuff). Just frustrating really – and I wanted to share my experience with the other knowledgeable sysadmins of present and of past.

OVMRC Meeting & Course Graduation

Tonight at the OVMRC general meeting for March, we celebrated the graduation of the entire course. To have every candidate pass the Basic exam is quite an accomplishment and is a testament to the quality of the course itself.

It was nice to see almost all of my cohort make it out to the graduation – we all hope to see each other at the next general meeting in April, and more exciting, we hope to hear each other on the air over the next little bit!

After the graduation ceremony, the attention shifted to home-brew night where there were a number of excellent projects on display. I will leave the details to the club newsletter (which can be found here).

Update: Here is a clip of Ernie (VE3EJJ) demonstrating his project:

After the meeting, some of us met at the local coffee joint for some drinks and junk food. It was nice to have some more time to chit-chat with everyone before we all went out separate ways.

All in all, it was a nice evening and I enjoyed seeing everyone out at the meeting. I really can’t wait for field-day; I hope that I can get the time off from work!

FT-101E Project: Phase 01

So just over a week ago, I purchased a boat-anchor from Robert (VA2AGE) who was also kind enough to lend me a SWR meter and a dummy-load . This beautiful little gem is a Yaesu FT-101E which dates back to some time around 1975. The radio is a hybrid in that all components except for the final drive circuitry are solid-state. The finals are tube driven and use 6JS6C Tubes. For more information on the FT-101 series of radios, I recommend a peak at the Fox-Tango group.

After some very brief testing, it appears that the noise-blanking circuit is shot – it causes noise when I turn it on. Some advice given to me from a repair tech I met yesterday suggested that I try replacing the diodes and transistors with equal value replacements.

Using a piece of old phone cord, I was able to tune in a station down in Cuba transmitting on 7.375MHz (40m band). The signal came in very strong, however, I still had some issues reducing all the background noise.

My intention is to get a PL-259 patch-cord to hook up a test rig as follows: TXVR-SWRmeter-DummyLoad.

Once I figure out those logistics, I’ll try tuning up the radio for TX – though I still need an antenna tuner and some long wire!
