This week’s Newsletter continues the “Project Edition” theme.
N5OP sends an update on his Kenwood TS-930S refurb job,
N5HZR has Part Two (of three) of his tips on building the Pixie Kits that a whole bunch of you ordered,
I introduce you to KD7VUM’s wonderful DIY/Info site,
Ham Nation chimes in with discussions about repairing stuck rotators “at the top of the tower”, an evaluation of “heat shrink tubing”,
and the ARRL Letter leads with a “Ham Census Update” and other good stuff.
It’s not in “Dates”, but Green Country is the weekend of the April club meeting, and if you are inclined to go, the Friday evening session is really, really good.
You can find EVERYTHING you need to know about that at this link:
I HOPE that you haven’t packed-away your Winter Clothes yet,
and have a great weekend – see you on the air!
Making An “Old” Radio New, Follow-up
Kim, N5OP, sends this follow-up to his post from last week. GOTCHA!
Recall that I said “everything works?” Well, this morning I learned that, no, not everything works. The rig had no tx audio for ‘phone. While I don’t operate phone much, it’s on the switch and so I think it oughtta work. There wasn’t even a little audio, there was no audio at all to the tx. None. Zilch. Nil. Nada.
I get home tonight and decided “Alright, immagonna wrestle this to the ground!” and dig in. First off, I find that the schematic is wrong: it misnumbered and mislabeled the audio connector on the signal board. No worries: I trace everything back and determine that, yes: the wire from the mic connector to signal board is good and, yes, it’s plugged into the right spot. But, as I touched the connector, I thought to myself “Self, does that connector seem a bit loose to you?” It seemed to wiggle a lot — especially compared to the other connectors. “Well… That can’t be good.”
OK! Fine, Murphy! Have it your way! I’ll take the signal board out! Again. Twenty-plus connectors and ~20 screws later, it’s out. I look at the audio connector on the foil side. Well, I’ll be dipped!
The land to which one of the pins is soldered has come up from the circuit board material because the copper foil adhesive has failed. And… Could that be? Get the magnifiers out… Yes! The foil is broken right at the solder pad! I repair it and decided to do some preventative maintenance on a couple of others in the neighborhood. Mind you! I’d never worked anywhere near there!
It’s back together and Lo! And Behold! now it really does all work. What would I do with all my spare time if I didn’t have to fix this beast? Oh, yeah: be on the air with it.
If you plan on doing stuff like this, one of your FIRST things to buy is a self-supported magnifier, or at worst, wearable magnifiers. For Kim (and you if you should go down this path), he gets to keep his beloved radio for another decade or two of enjoyment rather than trying to hunt down someone else to do the repairs and mods, or junk it altogether and shell-out for a new/different rig.
[Editor’s Note: My DIY projects usually involve such high-tech components like “bailing wire”, which I submit lasts much longer than paracord!]
Pixie Build, Part Two
This week we talk about actually building the radio. You’ll see from the photo below that our parts have all been organized, and you should be able to proceed with the installation. The resistors are on the top, capacitors to the right, inductors and diodes to the left, and the egg carton is full of little parts and pieces. Grab a copy of the Installation and User Operation manual from the http://w5nor.org/pixie web page, and you’ll be ready to go.
Next you can start mounting the parts on the board. This process is usually called stuffing the board. Take a look at the circuit board, and you’ll see two different looking sides. The side that has all of the wording and part labels is the top, or part side, of the board. The other side is the bottom, or solder side, of the board. The general rule is that you mount the shortest parts first. Start with the resistors, diodes, capacitors, and inductors. Place each part, one at a time. Make gentle 90 degree bends in each part lead, and push them into the proper holes on the circuit board. Press the part into the top, or part side, of the board, and spread the leads on the solder side of the board to about 45 degrees, keeping the part from sliding out. Be very careful with the first part you place. Make sure you’re stuffing the board from the correct side.
Typically you place all of the parts of a given type, like all resistors, then double check that you’ve placed the correct resistors in the correct holes. Solder these parts in place, verifying that the solder has connected the board to the part and the piece is mechanically solid. Heathkit reports that 90% of their problems were caused by bad solder connections. Take your time. The assembly is the FUN part of these projects, don’t rush through it. When all of the leads have been soldered, use your side cutters to clip off the leads. Be careful when cutting the leads, hold the lead as you make the cut. If you don’t, the wire will fly across the room causing damage to your, or someone else’s eye.
Once you’ve done all of the resistors, repeat this process with the capacitors, inductors, diodes, transistors, crystal socket, LM386 socket, and all of the other items. Place the parts, verify their proper insertion, solder them in place, and clip the leads. Check off each part as you place them on the board. Between each type of part, take some time to inspect the board. Make sure all of the solder connections are solid and make sure there aren’t any solder bridges that make connections that shouldn’t be there.
Next week we’ll put the final parts together, and the fire up the transmitter!
