Last update 5 Aug 2013

The Military Radio Collectors Association, organized in 2000, is intended to bring together people with a genuine interest in the subject.  It is an outgrowth of the Old Military Radio Net that meets every Saturday at 05:00AM (prevailing Eastern time) on 3885KHz in the 75-meter amateur band.


MRCA Fall Meet,  20 - 21 SEP 2013
West End Fairgrounds, Gilbert, Pa.

The Military Radio Collectors Association will hold its 2013 annual meet at the West End Fairgrounds, Gilbert, Pa.  The event will, once again, be held in conjunction with the Red Ball Military Transport Annual Show.  Activities will include equipment displays, on-the-air operation, and formal presentations. 

The Site:  We have comfortable indoor space for displays and presentations.  Please bring your own chairs and display tables.  There is ample outdoor space for tailgating.  Primitive camping is permitted on site.  Well-kept bathrooms and hot showers are available. You’re welcome to show up early Friday and stay over until Sunday AM.  Fairground management is concerned about risks associated with hanging antennas in trees.  To keep our tree mounted antenna exposure to the minimum please plan to bring appropriate supports if you intend to erect a vertical or a skywire.

GPS:  Use "Fairground Road, Gilbert, PA."  Coordinates of our building: 40.911045N  75.430707W 

Equipment Displays:  This is the place to show off some of your prize pieces to an understanding public.  Signage identifying your equipment is really helpful and educational.  There will be an organized, walk-around, “show-and-tell” following the formal presentation session on Saturday.  Deployment of operating radio stations is encouraged.

Tactical Field Radio Exercise: On Friday afternoon we will once again be sending long range reconnaissance comm teams to a number of remote sites.  Saturday morning's activities following a MRCA breakfast will include a medium-range field radio team deployment in the Gilbert area.  Saturday afternoon there will be a short range net with HT (BC-611 and MAB type radios) and back-pack radios. This is a great opportunity to use all our low power field sets as intended and should be lot of fun (charge up your batteries!).

Gate Pass:  If you are arriving for setup on Thursday, 19 Sep., print out this PASS, and present it at the gate.

 

Watch this space for further info in the near future.

MRCG - Western USA
- Saturdays: 09:00 (Pacific) - 3985 KHz AM
- Wednesdays: 20:00 (Pacific) - 3996 KHz USB

Suggested Frequencies:

75 Meters:  3885 KHz - Primary AM frequency for short, medium, and log range at MRCA and other events.

6 Meters:  51.0 MHz - Primary FM frequency.

COMMENTS:  Military sets operate "wide-band" FM.  There is a dicotomy between the early sets that used noise squelch and more modern radios that use 150 Hz tone squelch.  I.e., if you call on a PRC-10, a PRC-77 user won't hear you unless his squelch is disabled.

6-meter FM "ham" sets can interoperate with the militaqry rigs, but transmit audio will seem weak due to the lower deviation, and receive audio is likely to be distorted do to the higher deviation from the mil sets.  Many ham radios support 151.4 Hz tone squelch, however the frequency tolerance of the tone transmitted on the military sets might not be close enough, and the transmitted 151.4 is likely to be too low in deviation to "break squelch" on the military sets.

2 Meters AM - We have not settled on a single frequency:

144.25 MHz (Several MRCA folks have URC-4 pilot's survivals set crystaled here.)

144.36 MHz (Used by WWII aitcarft.  There are crystals floating around.)

144.45 MHz 

H.F. Packset Freq's:  

1996 KHz, 3996 KHz, 5403.5 KHz, 7296 KHz, 14.342.5 KHZ, 18.157.5  ALL USB
