I'm making an attempt at building a 2-meter repeater out of two of them. I've heard from several people that, as long as there are not temperature extremes, you don't need a channel element as the crystal will plug directly into the radio without the element. Maybe I could build a "heater" using a thermister -- I'll have to check my manual -- which I received in today's mail -- and see. Thanks. Jeff |

Astron RS-12 Schematic
Kevin K. Custer W3KKC
Does anyone have a schematic for an Astron RS-12A?
A person emailed me directly and ask for a copy which I could not help with. If you do, can you scan it and email it to me. Required size is approximately 900 high by 600 wide so it will print out on a common sheet of paper when printed. Image file size should be no greater than 100k (see ) If you have a copy of the schematic and have a scanner, I will give you pointers on how to scan the image and make a nice printable copy that doesn't require a lot of size. Thanks, Kevin |
Large Heat Shrink
Kevin K. Custer W3KKC
I was asked to post this again, so here goes....
Hello All, I recently received several requests from people on the list wanting to obtain the large heat shrink I use to seal the Comet and Diamond fiberglass antenna joints with. This stuff is great for sealing connectors, antenna joints, covering shovel and sledge hammer handles and covering tool handles like large Crescent wrenches. This shrink has an inert sealant that melts as the heat is applied for shrinking. This creates a good (won't leak if it was drug across the Atlantic) seal. Well maybe not that good......but damn good. It is available from Jerry Conn Associates Inc. They are located in Chambersburg Penna. The manufacturer is CANUSA. Pronounced canoosa. The available sizes (unshrunk of course) are indicated by the model number. Example: Part number; CFTV-400 is .4" (that's point 4 inches) CFTV-1100 is 1.1" diameter CFTV-1300 is 1.3" diameter CFTV-2050 is 2.05" diameter and so on These come in a 4 foot length. I believe the shrink percentage is 50% of original, This is not fact however. I don't remember the spec. on shrinkage off hand... but it does shrink a lot. These are the available sizes: The ones with pricing are normally in stock. CFTV-400 CFTV-750 CFTV-1100 CFTV-1300 $5.16 CFTV-1700 $5.95 CFTV-2050 $11.41 CFTV-2750 These people have a $50.00 minimum order, so get together with a friend or two and place an order. They will sell directly to the public. The models listed without pricing are available through JCA, but are usually not stocked. If interested in purchasing, contact Tracy at Jerry Conn Associates. 1-(800) 233-7600 in PA 1-(800) 233-7370 out of PA 1-(717) 264-1547 Direct Line from anywhere. The CFTV-750 is great for RG-8/PL-259's or Type N connectors. In our business, we use a propane torch to shrink the tubing. It's wall thickness is very good, and not easily damaged by a little excess heat. You can actually catch it on fire and not damage it badly. It doesn't shrink well in windy conditions, (requires lots of propane) In severe wind I use MAPP gas as it gets burns hotter than propane, although this is usually not necessary. I have used this stuff for years and can attest to its quality if installed properly. There are other cheaper brands of this stuff than CANUSA , but (in two words) they suck. There is no equivalent. I tried them all. Here is a pix of the stuff we use in the catv industry. [Image] They also have a good quality Self Amalgamating Tape that is much better for covering connections than Black Tape.

You will, however, loose gain in the direction of the three elements by facing one in another and could have a problem if you are on a large tower. The elements must remain at the required vertical spacing. At 440 and up, you cannot - they must all point toward the same direction. You might get away with it at 220. Chuck Kelsey WB2EDV |
I Have a few questions on repeater Antennas
Michael Lussier
I am looking for some help with antenna questions for my GE MASTRII/RANGR
Repeater What is the consensus on 4 bay dipole arrays for repeater antennas ? I have looked into the coverage maps with both the 4 bay dipole array and an Omni stick. The closest repeater on the same pair is 50 miles away. The idea of going to the array was to place a null in the direction of the other system. According to my coverage maps it cleans up and expands my coverage going to the Omni. Now for the second part of the question. The 4 bay array antenna have a phased harness can I put three of them at the same level and the fourth antenna as a reinforcement in the direction I want ?? Currently the 4 antennas on the array are on the western leg pointing North and South my coverage is for no better word Terrible 7 miles away to the east I get an S4 , to the west 20 miles an S9 /Mike From The Heart of Spotsylvania County, Va. 146.775 - / 203.5 442.850 + / 203.5 [[ MICHAE~1.VCF : 33 in winmail.dat ]] |

band, but I don't recall how. I probably had to edit the hex data. If you can't find anyone else who can do it, I'll research it more. It can be done. :) *** One word of warning: The oscillator becomes intermittent at low temperatures (<20-30). I don't recall how I got around that problem either, but I think it involved adding or removing a transistor. But when it works, it works very well. Joe, KR3P D.J.H. wrote:
