Take the example of radio-mart. In 2003 his alter-ego, gottahaveit1995, was bidding radio-mart's auctions and even listed feedback (positive, of course) on radio-mart's feedback pages. Radio-mart appeared suspended in Spring of 2004. Some three months later, radio-mart reappeared as a registered user and started selling again. The feedback from gottahaveit1995 on radio-mart's feedback page then (conveniently) disappeared....yes, ebay erased it! The bottom line here: if ebay "fixes" someone's feedback to coverup an obvious fraud....how much credibility does ebay have, let alone their much-faulted "feedback" system. To me, the feedback system remains a joke. wrote in message news:1121202629.469012.139580@g49g2000cwa.googlegroups.com... > Here's a seller on ebay that has Radio-Mart beat by a long shot.

I would bet a control circuit failure. Measure the voltage across the fan and see if there's anything there. I bet there is not. If the motor has failed, you will probably not see DC continuity across it either. While you have it open, put a drop of turbine oil on each of the motor bearings so they stay good. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

With broken heart, I've probably thrown away 10 or 12 of these when I quit
my marine electronics business. Now that I want to return to real Ham radio,
and have no transmitter, I'd like to convert this old rig into an 80 and 40

having a real schematic (or one that's fairly close) would make memories

If you obtain a schematic, I sure would like to get a file copy of it.  I
worked on lots of marine equipment in the mid 50s, but never a Pearce
Simpson that I can recall.  Worked mostly on Northern Radio and Apelco.  In
Ketchikan, AK, any boat owner who could afford it had a Northern, along with
a Zenith Transoceanic and an S38C at home.

Your conversion to 40 & 80 should be quite simple.

I also have a Pearce Simpson in my storage. Would also like a copy of the Schematic.

B.H. Brian's Radio Universe http://webpages.charter.net/brianhill/500.htm Article: 99375 of rec.radio.amateur.boatanchors From: Edward Knobloch Subject: Re: Fuse for TS-830 & Neutralization ? References: Message-ID: Date: Sun, 17 Jul 2005 15:43:05 GMT Hi, I would think that you would use a 3 amp fuse if wired for 220V, 6A for 110V (I don't have a Kenwood manual to check this, but a 6 amp fuse sounds right at 110V). First check your resting plate current before tuning up. With PTT set to transmit, and no drive/no audio, the finals should draw about 40mA plate current. If not, adjust the bias control for this reading. The proper way to dip a pi net final is to start with the loading capacitor fully meshed. Apply some drive and quickly dip the final plate current using the plate tune control only. Then apply full drive* (see note) and read the plate current (it should be much less than the rated 250 mA). Assuming it is less than the desired 250mA, increase the loading control slightly (say, enough to result in a 20 mA increase in plate current with full drive)and then quickly redip using the plate tuning control. (+Always+ redip with the tuning control last, or you will be operating with your final out of resonance). Note that you are always dipping with full drive applied. Note that you can dip the final using the plate tune control while less than full drive is applied (easier on the tubes), but you then must increase the drive to full drive to see if you have reached 250mA plate current at dip with full drive, which is your goal. Continue this procedure until either the rf power output no longer increases when you increase the load control with drive, or you have reached 250mA plate current at dip with full drive, whichever comes first. Do not operate with more than 250mA plate current at dip, full drive, or you will overheat your finals. *Note: By "full drive", I mean enough drive for the plate current to stop increasing very much with increasing drive (saturated), not that the drive control is fully clockwise. If you don't get around 100W rf out at 250mA dipped plate current, one possibility is that the final tubes are not well balanced. With the bias set for 40mA with both finals installed, if you remove one, the resting current should be 20mA. If the tubes aren't well balanced, one tube may be hogging all the current, and the rig will be unable to deliver more than about 50 or 60 Watts. Note: remove one of the tubes completely for this check, do not just remove the plate connector of the unused tube, or it may be damaged by excessive screen current (the screen tries to act like the plate). Caution: high voltage at plate caps of the 6146's - keep one hand in your pocket when you poke around near the final cage. Use a shorting stick before touching the plate cap. To check neutralization, you transmit with no drive, PTT on, no audio, (i.e., same set-up as 40 mA bias check), and with the loading capacitor fully meshed, you rock the plate tuning capacitor throughout its full range. The plate current meter should remain at 40mA. Any sudden, drastic increase as you vary the plate tune capacitor with no drive in this manner indicates a neutralization problem. Note: this can be a destructive test, as the onset of a parasitic oscillation can be sudden, with very high plate current. Be ready to turn off the final quickly. A dummy load is best for this test, rather than an antenna. 73, Ed Knobloch Gary wrote: > I bought a TS-830 from a ham friend that buys estates etc. He couldn't > get more than 30 watts out of the '830.

Program METALFLM.exe 41 Kbytes. This program models small low-wattage wire-ended resistors including spiralled metal-film resistors. The model's equivalent circuit is a chain of T and L networks. Values of lumped inductance and stray capacitance are estimated by the program from the component's physical dimensions. The component with it's terminating leads is treated as a lumped L and C non-uniform transmission line. The program computes input impedance >from 10 KHz up to 5 GHz with the other end grounded. Fast and slow frequency sweeps are available to observe maxima and minima of Zin. Max and min Zin are approximately related to the physical length of the component, including connecting leads, but occur at frequencies far higher than the usual and useful working frequency range. The reflection cefficient and standing-wave-ratio are calculated with reference to Zo, Zo being the DC value of the resistor. The usefulness of the component as a dummy load or for other purposes at any frequency can then be ascertained. The effectiveness versus frequency of solid carbon-rod resistors and multi-turn UHF chokes, which are of similar wire-end construction, can also be determined. Chokes can be wound over the bodies of high-value wire-ended resistors, the parallel resistance value perhaps having some desirable effect on the ultimate response. Another use for resistors having a good high frequency response, or at least a known frequency response, is for ratio arms and switched resistors in impedance bridges and other measuring instruments.

I need the following parts: (1) "Preselector" air variable capacitor assembly (2) crystal for 28.0 - 28.5 MHz (10m CW) (3) crystal for 10.0 - 10.5 MHz (30m) I suspect that 2A parts will also work. I know that 4-Line parts will not work. 73, Dean K5DH Article: 99386 of rec.radio.amateur.boatanchors From: "sb" Subject: Codar AT5 Date: Tue, 19 Jul 2005 12:42:30 +0000 (UTC) Message-ID: I'm trying to build a transmitter based on the Codar AT5, does anyone have coil details for L1, L2 and L3 of this transmitter.

The AR-88D is a 98 lb. beast! Here's what I do. Good engineering practice calls for a minimum of 1 RU between rack mounted items. I have two 1 RU panels with fairly beefy angle stock mounted on them. Put one on the front of the rack, under the radio and attach the other to the rear rack rails. Cut some pieces wood long enough to firmly rest on the angles and thick enough to fit snugly against the bottom of the unit. Note- it has to fit against the bottom of the unit, not the bottom of the front panel. Pop the rack screws out of the unit and your unit should rest comfortably on the temporary shelf making it much easier to slide out. Makes it even easier to slide in since you aren't trying to hold the dumb thing in place while inserting the screws. This may be easier to visualize than describe. If there is any interest, I can do a quick PDF. And some day I'll tell you how I get my 250 lb. FRR-59 into a rack by myself.

Date: Tue, 19 Jul 2005 09:15:13 -0500 Message-ID: FS: I have about 5 or 6 legal size boxes of Marine radio service manuals. I got them from a friend who used to work at Radio Holland in Houston. They service shipboard radio equipment and when the ships dumped HF radios for satellite stuff he got a pile of their old manuals. No, I am not going to look for a specific manual in all that stuff but I am going to offer it all as one lot to whomever might need the stuff. Some of the names I saw in there (many more too) are Sailor, Motorola, Data Marine, SAIT, Marconi Marine, MacKay, Icom, Debeg, etc. If anyone is interested before I post it all on eBay, let me know. $125 takes all.
