Most of them can be bent cold if you use a great enough radius. www.mcmaster.com has a handy chart of the workability of the various types of stainless (insert stainless into the search criteria and look under brake forming as the closest operation to what you are proposing.) It ranges from excellent to difficult, so you will need to know what you have before proceeding. Keep in mind that heat will alter the temper and in some cases the composition of the metal, even if it's not heat treated. It can also introduce side effects like a propensity for greater corrosion in the heated area. I love working in stainless, but remember that it is a metal that work hardens in any forming or machining operation. 73, Mike de KC4TOS Richard Dillman wrote: >I have need to bend a stainless steel whip antenna about 45 degrees so it will be vertical in a mobile installation. > >I've seen some that have been bent and those have a discolored area at the >bend that seems to indicate heating. > >Does anyone have direct experience in doing this?

Unusual item about this transmitter is the use of multiband tuners for the interstage and output tank circuits. As a kid in high school, I wanted to build one, but never found the time or the parts. Fast forward to recent times, I came across two of them, built by two different people. Construction practices on one of them is excellent plus. The other, just average. Some variation in layout, but overall the two transmitters followed the circuit closely. Trouble is, neither one works, and they both don't work the same way. Both work fairly well on 80 and 40, but on the higher bands, getting the resonant points of the driver and final to line up properly, and the 40 meter resonance of the driver tank seems to swamp out the 15 and 10 meter resonances, making the final act more like a multiplier than an amplifier. So the question I have is: Anyone ever build one of these and make it work? Jack Jack Antonio WA7DIA scr287@sbcglobal.net ------------------------------ From: "Richard W.

What think you of its basic performance, weaknesses, strengths? It would replace a National NC-125 (also in fine shape). The -240 is an older design, I'm guessing maybe 5-10 yrs older than the -125. The 125 uses some later tubes, e.g. 6SB7Y for mixer instead of a 6K8, 6SG7 for RF amp instead of, I think, 6SK7, but both are using octal tubes. The -240 has pp 6V6's AF outputs for potentially nicer audio. And the -240 has that mechanically amazing, but complex, bandshift arranging of coil sets being shoved in & out of use. Is this a problem area? Of course, it can give higher Q RF performance to the radio, a la HRO's. The 240 is clearly a considerably more deluxe radio than the 125, but does the age of its design put it behind? As always, thanks for your inputs in advance. --John Sehring WB0EQ/VE6 ------------------------------ Message-Id: <6.2.1.2.2.20070325144007.02f7a360@pop-server.nc.rr.com> Date: Sun, 25 Mar 2007 14:55:15 -0400 To: Old Tube Radios From: john Subject: BAs for sale at the Raleigh NC fest Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed Will be hauling the following (at least) to the Raleigh hamfest next Sat night, and Sunday morning.

The NC-240D is one of my favorites of all my vintage receivers; it is not the best performing but the performance is good and CW selectivity is fine when the xtal filter is aligned properly. It has excellent audio, good mechanical and thermal stability, and a very nice tuning feel. I particularly like the way it is set up to select either general coverage or bandspread ranges. It does not have quite the performance of an HRO-50 in terms of selectivity, stability, and sensitivity but it is not far behind. The NC-125 is what I think of as one of my "OK" receivers; it works OK and I have used it with my Knight T-60 as part of a CW station. It has the interesting "Select O Ject" circuit built in and it performs in a competent manner. If the NC-125 were an employee you wouldn't fire him but on the other hand you wouldn't promote him either. I think that even though the NC-240D is a bit more elderly you will like the performance of it better. There is an article somewhere, written by Bill Orr I believe, which provides some modifications for the NC-240 family to increase the sensitivity on the higher ranges. I believe it involves the change of the mixer and perhaps the RF amplifier tube. I have several of the "switching coil catacomb" family of receivers including an NC-100, NC-101X (ham bands only), RAO-7 (Wells Gardner built military version with a second RF stage), and a 240D. I have had no mechanical problems with any of them and as long as someone hasn't done anything terrible to the sliding coil drawer/contacts you should not expect problems. I just recently restored a Pierson KP-81 which also uses a sliding coil drawer and must have been inspired by the National design though it is mechanically even more robust than the National setup. Do check carefully as at least some of the 200 series receivers mounted the output transformer in the speaker as was done in the original 100 series receivers. If the one you are looking at is like this then make sure you get the matching speaker or you will need to add an output transformer. In short, if I were choosing between the two I would definitely take the NC-240-D. And if you are fortunate enough to have any decent BCB stations in your area you will enjoy the excellent audio the 240D produces. 73, Rodger WQ9E John Sehring wrote: > Came across a National NC-240-D in nice condition. > > What think you of its basic performance, weaknesses, strengths? > > It would replace a National NC-125 (also in fine shape). > > The -240 is an older design, I'm guessing maybe 5-10 yrs older than the -125. > The 125 uses some later tubes, e.g. 6SB7Y for mixer instead of a 6K8, 6SG7 for RF > amp instead of, I think, 6SK7, but both are using octal tubes.

It has a 6SG7 RF state, a 6SB7 converter, with 6SG7s in the IF. The IF cans use 500p caps, making the unloaded coils impedance lower, with a resulting higher loaded inpedance. A very good receiver. Like a lot of boatanchorists, I have used the NC-57, the NC-125, the RAO, the NC-240d. They are all good receivers. While I didn't compare the sets directly, I think the NC-125 has better sensitivity. The RF coils are National's X-50 coil forms, which usually have Qs greater than 100. The 6SB7 is a low noise converter, designed for the 100mhz FM band and having a Noise resistance of about 65k versus the 220k noise resistance of the 6K8. I had better stop ranting. The NC-57 is my favorite receiver, as you can detect.
