Message-ID: Date: Mon, 14 Nov 2005 17:05:25 GMT Gents, I have acquired a Drake TR4 with power supply that track accurately on 80, 40, 20, 15 meters. The dial on the three 10 meter bands indicates about 30khz higher than actual. I have tried to adjust the touchy L2 accurately, looked at T1 for problems and swapped V1 tube. There are no cracked ferrite cores. Other hams on the air have told me this is typical of this TR-4 gear on 10 meters. Is there a component or gimmick that would bring the 10m tracking back on? Does having the 6JB8 PAs screen and plate B+ disconnected affect the 10m band in this way (I would think not)? What am I overlooking? Thanks, Paul.

If you are lucky just tweaking the oscillator coil will snap it back to where it belongs. As the other guy pointed out, though, the oscillator might have been monkeyed with if some CB'er tried to modify it. Also there is a better source for the TR4 manual, with better schematics.

This "will" upset genuine CB radio operators, and those who did advance to Amateur from CB, as many full licence Hams dont seem able to distinguish between the two, or dont want to distinguish... thats the problem.

Maybe not to the point of disconnecting his/her equipment but at least bringing up their kids to be respectful of things. I would personally put a lock on the "shack" door so I could secure the room but some people have them in their living room so sometimes I guess its asking for trouble. My CB is in my office and also one in my repair "shack" and when I go out I make sure both are locked.

That's a common myth. Neither type has a constant voltage during discharge, but the NiMH is much more constant than alkaline. Try this experiment: Put a resistor across an alkaline cell to simulate roughly the load a GPS receiver would present. With a DVM, check the voltage every half hour or so, and continue until it reaches 0.8 - 0.9 volts, which is where it'll be when nearly all its energy is gone. You'll find that the "1.5" volt alkaline cell voltage will reach 1.25 volts (about the voltage of a NiMH cell for most of its discharge period) at a point where half or more of the cell's energy still remains. That is, the cell voltage will be below 1.25 volts for half or more of its life. If you repeat the test with a NiMH cell, you'll find that the cell voltage is 1.2 - 1.25 volts for nearly the whole discharge cycle. So for about half the time, the NiMH cell will have a higher voltage than the alkaline. Or, you could do it the easy way and look at the curves supplied by the manufacturers. They're readily available on the web. If a device quits working at a cell voltage of 1.0 volts, you'll get nearly all the energy from a NiMH cell, but you'll be throwing away an alkaline cell that still contains a significant amount of energy. > I noticed that when the GPS switched itself off when using NiMH batteries > ,the cells apparently were not fully discharged. > Using an automatic NiCad /NiMH charger operating with an initial discharge > period as part of the overall cycle, > it took quite a while ,before the NiMH cells were discharged before charging > commenced. Sounds like something was wrong with the GPS. If there was signficant energy left in the NiMH cells, it quit at a voltage greater than 1.0 volt/cell. And if it did that when using alkaline cells, you'd be throwing away an even bigger fraction of its total energy than with a NiMH cell. There are several reasons why NiMH cells might not do as well as they should. One is that chargers will often shut down well before the cells are fully charged. This is particularly common with new NiMH cells, until they've been cycled a half dozen times or so. Another potential problem is voltage depression, mistakenly called "memory". This can be cured by a full discharge to 1.0 volt/cell then recharge. Cells also have less capacity after long storage or a history of light use and recharge. Several cycles are necessary to restore full capacity. And of course, modern NiMH cells at 2500 mAh or more have a lot more capacity than earlier ones which were as little as 1300 mAh or so -- if you did a comparison some time ago, things have changed since. A number of fast chargers don't charge cells to their full capacity. Finally, a substantial portion of some cells' capacity originates in the marketing department -- tests I've run show the capacity of some to be pretty badly inflated (Lenmar is a common brand that comes to mind). They do take some care and feeding -- if it's too much of a hassle, alkaline cells are a solution.

Sure, the voltage regulation isn't that great, but it's not the main problem. Looking at the diagram for the VFO you can see the tuned circuit components. You can add a negative temperature coefficient capacitor to the circuit to compensate for the (usually) positive coefficients of the parts. I did this successfully in a Viking Valiant. I reduced the drift from about 10kHz or more on 10 meters to about 1kHz. One thing I did was move a hot resistor out of the VFO compartment to reduce the amount of temperature rise of the critical parts. You can also leave the unit on, at least the VFO, at all times so the temperature will be more stable. 73, Bob K6DDX Article: 94981 of rec.radio.amateur.homebrew From: Ken Scharf Subject: Re: FA: NOS Western Electric Command sets + mo...

I wonder if they had a temp compensation adjustment. Consists of one positive and one negative coeficient fixed cap of the same value, each one tied to one side of a differencial trimmer cap, the other side of each cap tied to the tuned circuit.

But across the inductor is the first place I would try. Of course you will have to reduce any other capacitors by that amount so that the circuit will resonate at the same frequency as before. As someone suggested, a differential arrangement will work but it's a bit tricky. I'd prefer to substitute various values until I hit one that is close enough.

One alternative could be to add a varactor (and a series capacitor) into the resonant circuit and vary the varactor control voltage according to the temperature. A suitable NTC or PTC in the voltage divider feeding the varactor could be used.

I don't know how to convert the hex into a different frequency. It can be done. I have done it in the past but I lost the instructions on how to do it manually when we moved.

The PIC microcontroller will then understand the signal and increase or decrease the speed of the motor accordingly. (Basically the concept is based on a remote control cars which kids play with).

Ron- Does the equipment it came out of happen to have "FC" in it name? It could be a proprietary part made for that company. As such, Westinghouse would probably never reveal the specs to anyone else. Could there be any other markings on the device? The FC442 might also be a form of date-code, such as 42nd week of 2004 or 1994, 1984, 1974, et cetera. You may be able to determine a reverse breakdown voltage with a variable high-voltage power supply and a current-limiting resistor, but you may have to analyze the circuit it came out of for a minimum current rating.

During a power outage, which occurs frequently in Florida, I would like to use a battery to power some communication gear. Although the battery is 12v and not 13.8v, I think that the gear will still work OK (hopefully). Question 1. I believe that car batteries have a low internal resistance because their primary function is to provide a lot of current for a short time. There are other 12v large battery types that will last as long as a typical car battery. They are designed not to provide peak current, but to supply steady state current for a long time. For the life of me, I can't remember the name of those type batteries so I can't do a google to find a supplier. I hope this is making some sense. Question 2.

What you want is a deep cycle battery. Sometimes called a marine battery if it is about the same size of a car battery. Used for trolling motors among other things. Also used for powering golf carts. Article: 95009 of rec.radio.amateur.homebrew From: Ken Scharf Subject: choke input voltage doubler? Message-ID: Date: Fri, 18 Nov 2005 22:30:51 -0500 I was looking at some power supply circuits for tube linears and was thinking about the full wave voltage doubler. This is basicly two half wave rectifiers in series. Now I could build this circuit with a choke input filter for each half wave rectifier of the voltage doubler, and I could put the chokes in the lead without the rectifier. In this case I could use one choke for both halfs of the voltage doubler. The output should then be about .9 * rms input voltage * 2 or 1.8 times the rms voltage of the transformer. Has anybody ever tried this? ------>|-------- ) | | ) | --- ) | --- )-----^^^^^^----| | | | --- | --- |--|<--------| Crude schematic showing transformer secondary diodes filter choke and capacitors.
