MISCELLANEOUS DOCUMENTS

Here are some assorted documents which weren't on the web anywhere else and which seem to have been in demand.  This list will get longer as time goes by.


MILITARY URM-25D SIGNAL GENERATOR "Lankford Notes"

Here are the notes written by Dallas Lankford in the 1980's which were in Hollow State Newsletter regarding rebuilding the military AN/URM-25D signal generator.  It's my understanding that Ralph Sanserino, the publisher, passed away a few years ago and they are thus no longer available as a hard copy. Thanks to Don Spellman from the Antique Radio Forums for the scan.  This is about a 900 kb file.  You will need Adobe Reader or an Open Office equivalent, this is a pdf document.

MOTOROLA LTS2000 / LCS2000 SOFTWARE HACK TO 900 MHz

This is my page describing how to modify the software for the Motorola LTS 2000 portable or the LCS 2000 mobile to take entries of ham frequencies on the 900 MHz band.  You will still need the software itself, preferably as late a version as you can get, and a hex editing program such as HxD or Hex Workshop.

KENWOOD KPG 29D Software and TK760 Front Panel Programming

How to use the Kenwood KPG-29D software and how to use the front panel programming mod on the TK 760H and TK860 radios.  Please note I do not have other information or experience with these radios.

HULL 924 MARINE SSB RADIO PROGRAMMING

Here are the instructions in pdf form for programming the Hull 924 SSB radio. I do NOT have the manual for this radio!  Please note that the 922 Series is NOT the same internally, and that there is probably some work to be done on the VCO's of the 924 (as there is on the 922) to make it function on the 5 MHz amateur band.

REGENCY M100 SCANNER HAM BAND MODIFICATION

MEISSNER DELUXE SIGNAL SHIFTER PLUG-IN COILS ID (pre-1944)

This is a chart I made of the plug-in coil set part numbers for the prewar Deluxe Meissner Signal Shifter VFO/exciters.  The part numbers were originally printed on a cardboard disc glued to the top of each coil, but these discs fell out and were often lost over the years.  The part numbers were also printed in faint silver paint near the base of each coil.  If those numbers are still visible, you can use this chart to identify the coil's band.  Note that the coils have different numbers of pins on the bottom, so that they can not be plugged into the wrong stage.   Single Adobe PDF page.   CLICK HERE


MEISSNER DELUXE SIGNAL SHIFTER MANUAL (Pre-war)

This is a pdf of the composite manual Meissner made for the military during the Korean War covering the Signal Shifters produced up to 1942.  It covers all the Shifter models from the original through the 1942 model.   Apparently they were still using these at that time.  I have a Deluxe Shifter that is stamped "MFP" with a 1953 date (moisture and fungus proofing.)   The available Signal Shifter manual scans on the usual radio manuals download site were so horrible that I did this one to help people have a decent manual to work from.  I am working on scanning the EX- postwar manual.  Single Adobe PDF file.

NEEDHAMS EMP-20 MANUAL AND SOFTWARE

    A couple of years ago it appeared that Needhams went out of business, taking with it the web page and thus the software and the manuals for the EMP-20.  So I put that material here.  However, strangely, in summer 2013 I was advised that the website had reappeared and the company was back in business.  The last EMP-20 software version is again available from the company at     

            http://www.needhams.com

    As I am not sure what's going on I have left the software on my site, along with the documentation below (which may not still be available from them.)

    Note that the EMP-20 was also labeled and sold under the EETools brand name.  Note also that the software is a DOS file (not zipped) and the EMP-20 runs off the parallel port of an older PC in the DOS mode.  Please note that some browsers and virus programs won't let you download an .exe file (the software.)  You'll have to work around that if necessary.  The Device List shows you what you can program provided you have the little comb-looking PC board configuration key which slides into the side of the programmer for that family.

TWINLEAD J-POLE VHF ANTENNAS

For some reason this data was hard to find.  This is an instruction sheet I created for making a J-Pole style VHF ham antenna out of a length of old 300 Ohm TV style twinlead cable.  Ideal for things like Gonset Communicators and low power desktop base stations.   Adobe  PDF document, one page.   CLICK HERE


LOW BAND VHF ANTENNA WHIP CUTTING CHART - Ball and Spring Type

I didn't have any luck finding one of the old low band ball and spring antenna cutting charts on the web, so here it is.  If you need it, you know why.  This takes you to a web page.     CLICK HERE


UNIDEN BEARCAT BC 355N SCANNER TUTORIAL

The instruction manual for this scanner is very obtuse and leaves out simple instructions on how to enter and program frequencies.  This, I hope, solves that.  This takes you to an html web page.
