Topband: RX Antenna Switch
I recently delivered several RAS-8x2 Receive Antenna Switch units to customers and made some extras -- I have three units boxed and ready to ship. Two with UHF connectors, the other with F connectors. E-mail me at: gary(at)aytechnologies(dot)com And I am getting ready to make more of my past products and a few new ones. I've been making a few all along by request, but not advertising. Not ready with everything right now, but keep an eye on my web site www.aytechnologies.com I know this is a commercial message, but my 'manufacturing' isn't much of a business -- it's tiny, specialized, and I do it mostly for fun! 73, Gary K9AY _ Topband Reflector Archives - http://www.contesting.com/_topband

I haven't a clue of the methods of interlock switching the RAS8x2 uses but as it looks like we're going to have to make our own and my need to keep to simple click-clunk technology. I believe that using relays with a spare contact in such a cicuit that disables any other relay once operated, would do the job?

Re: Topband: RX antenna switch
Topbanders, Re: the recent discussion of antenna switches and the AY Technologies RAS-8x2 -- yes, production has been suspended while I work on my real job which now involves starting a new company (www.rfti.com for those who might be interested). I have only today started a conversation with a ham supplier who might continue the RAS-8x2 and perhaps other products I haven't made for a while. Even if that works out, there will be startup time -- hopefully, I can set aside time in February to work on a final batch of RAS units. No promises, but I'll try... Final note -- I have been providing repair services for the AYL-4 K9AY Loop systems made prior to Array Solutions taking over its manufacture. I will do the same for RAS-8x2 units already in the field. 73 and Happy New Year to all! Gary K9AY ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

Re: Topband: RX antenna switch
System similar to what you mentioned regarding the gain compensation/distribution, HPF/BPFs, RX overload, PTT, and additional signal path sources and output routing (incl. looping back): http://no3m.net/index.php?page=signal-processor Has an on-board embedded MPU, but a header can be used w/ switches for manual control. 73/HNY - Eric NO3M If it were the 'ideal' thing, there'd be a box with a matrix of switches (A x B), gain blocks that could be put in/out of the circuit, BPFs that could be put in and out, 'muting' of any RX output that is connected to a transmitter that is transmitting, RX overload protection, and some general purpose inputs to select the 'configuration'. Probably a PIC to run it, with a nice GUI app to configure it. - Brian N9ADG ___ UR RST IS ... ... ..9 QSB QSB - hw? BK
Topband: RX antenna switch
I'm sure that I'm like a lot of Top Banders in that I have a bunch of receiving antennas (5 at present) that I would like to switch to several different receiver type inputs. At present, I have a patch panel but am looking for something quicker and more convenient. It occurred to me that some sort of matrix switch would be ideal. A web search didn't turn up anything suitable. Any ideas out there? 73, Roger -- Remember the Liberty (AGTR-5) http://www.usslibertyveterans.org/ http://www.gtr5.com/ ___ UR RST IS ... ... ..9 QSB QSB - hw? BK
Topband: RX antenna switch
Many have suggested the K9AY switch. Unfortunately, I need more than two outputs. I have the two inputs to the K3, one to an auxiliary rx and one to a low freq converter...that's a minimum of 4. To cover possible expansion I'd like to have a 6x6, 8x6 or 8x8 matrix. I don't need any filters or preamps. 73, Roger -- Remember the Liberty (AGTR-5) http://www.usslibertyveterans.org/ http://www.gtr5.com/ ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

Topband: RX antenna switch
A new computer controlled RX or TX Antenna switch will be on the market in about a month. It will control up to 10 antennas or any other contact closure selection device with the click of a mouse. Users will be able to assign GUI designators to each port. Example for beverage selection the user may want to designate: NE, North East, EU, 45 or any other designator of choice... I have a prototype at my QTH and am doing field trial now. Details will be announced on Top Band and other venues. 73, Jack ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

The RAS 8x2 is the perfect solution. I have used mine for several years. I have 8 Beverage antenna directions going to two receivers in my K3, any combination of single/combined Beverage + Diversity.

Re: Topband: RX antenna switch
Here I use a basic 8 port antenna selector designed to my specifications by a ham friend of mine. The circuit boards are professionally etched and are equipped with chassis mount F female connectors. The single, 8 port boards can be daisy chained for 16, 24, etc. antennas selections. At this QTH the Beverage antennas are remotely controlled via the Green Heron 2 GHz system at a distance of nearly 1/2 mile. Currently the system is comprised of 19 separate antennas, each RF split 3 ways, with each split antenna selection fed to one of three separate groups of three of the above described boards. Results are at three operating positions each op has independent, totally separate control and visual readout of the direction and labeling of any of the 19 antennas. The visual is provided by a programmable compass rose on the computer display screen. Selection is by either clicking with the mouse which provides instant, opposite direction selection for an example, or via a USB rotary switch for normal step by step selection of the antennas. I have no connection with Green Heron other than I am in love with the upgrade of control capability their system has provided for my remote Beverage farm. It is so nice to have retired the old DTMF and basic CPU type controllers and control lines. 73, and good luck de Milt, N5IA -Original Message- From: W0UCE Sent: Wednesday, December 28, 2011 8:29 AM To: topband@contesting.com Subject: Topband: RX antenna switch A new computer controlled RX or TX Antenna switch will be on the market in about a month.

Re: Topband: RX antenna switch
The K9AY RAS 8x2 is very nicebut I wish it had an on screen GUI control. There is an interesting multiple RX antenna switch marketed at 4O3A.com that does allow for an on screen control and a multitude of RX antenna choices. This make it usable for remote operations which are growing in popularity for contests. Herb Schoenbohm, KV4FZ Thorvaldur Stefansson wrote: The RAS 8x2 is the perfect solution.
