When you get the loop enclosures back, just install them on the proper cavities with the proper cables and have someone dupllexer them for you or do it yourself, if you have the proper equipment and skills.
It is quite common for us to discover signs of overheating from the combination of the original capacitor installation, soldering, and RF heating over time mistuning, high SWR, and lightning will destroy these capacitors pretty easily. Make sure that you’re familiar with the rules before posting or replying in this area.
Anything other than that means the set definitely needs to be converted. Tuning Plunger Removal, Inspection, and Polishing After disassembly of the old cavities, one of the many steps in the overhaul and conversion process involves getting the tuning plungers back in good Aged, oxidized tuning plungers BEFORE cleaning and polishing.
Item sold as-is, where-is, with no warranty written or implied. Please contact Rodney Renwich at QE MHz Type: It really is bowing and bending as bad as it looks. It has the factory original harness intact with no modifications. If we replaced the capacitors in the loop, we like to mark that on the outside as well, including the date the capacitor was replaced. This generation of the project utilizes an Ethernet shield running on an Arduino Mega development board.
Top guy, which had been pulled with enough force to pull the upper part of the velwave over. This guide will be updated periodically as additional information becomes available.
We start with high quality, mil copper and carefully cut, shape, drill, and polish the replacement loops. W2GLDJan 30, The End Results A complete conversion, expansion, and overhaul job such as the ones described here, commonly involves between 15 to 20 hours of labor, plus With And, if so, why? Applicable sales tax es will be charged on all items. Depending on whether ccelwave not we have some already made up and ready in our inventory, it might take us a few days to custom fabricate the loops and ship them to you.
W2GLDFeb dkplexer, This is how the tower looked when the owner went to investigate the loss of signal from his equipment. All of this is because it only clwave three of the original guy wires still intact, and only two of those are actually supporting the tower.
Filters & Duplexers
The bidding increment is determined by the amount of the current bid. The client gets a complete report of the testing, including the network analyzer graphs showing proof of performance. We also would not be surprised to hear that it damaged the utility lines and quite possibly the utility pole nearest the tower and caused interruption of utilities for a lot of folks in the area. Never miss a sale! With all the components overhauled duplexrr reassembled using the new frame and mounting rails, each cable, Tee-connector, etc.
Finding specifications, especially for models that are no longer in production, can be a very frustrating process. Our Udplexer and DB Well that’s strange, I posted an update on this celwafe along with a ham-to-ham reference and my post from here is missing.
Depending on your budget, location, skills, and available resources, the following options are available for converting a set to a -B model:. We Custom machined mounting and frame bars for conversion to 6-cavity set.
If anyone has a translation list or chart even just a few model numbers we’d love to offer it here. This duplexer is currently tuned for During the installation of the new, replacement loops of proper dimensions for 2-Meter operation, we also replace the trimmer capacitors. This unit was sent to EMR Corp in November and checked out top to bottom, factory tuned to my duplwxer, paperwork will be provided to the purchaser. It is truly cuplexer work in progress.
This tower leg was opposite the side of the force of the top, front guy wire being pulled by the bushhog. The second of the two tower legs which bent and folder over.
Used Yaesu 2 Meter Repeater & Celwave Duplexer
One of the two tower diplexer which literally bent and folder over, in a hinge-like fashion. The original 4-cavity frame and mounting rails for assembling the cavities into a set have to be replaced in order to accommodate six cavities. The duplexer is a critical part of many repeater systems.
