Since my RAS-8x2 has been mentioned prominently in this thread, I'll give 
everyone an update...  Yes, I still make them! I don't keep any in stock, 
but usually have some preassembled boards and other components.


The majority of recent work has been custom systems for M/S, M/2 & M/M with 
various arrangements of filters & preamps. The 8x4 configuration has been 
popular lately. Made a 4x4 for the upcoming VP8 DXpedition.


Some of the other products I've made previously are available on request. 
None of them has much of a profit margin, and I mainly do them for past 
customers -- taking care of friends is a priority!

I have several Array Solution StackMatches that came with rotatory
switches.  I found the rotatory switches to be very awkward for changing
stack configurations and I quickly replaced them with MicroHam push button
controllers. They may also cause less wrist strain.

I have a K9AY 8X2 switch and it is awesome. Selecting RX antennas using
the remote key pad could not be easier or quicker.  The remote lays flat
on the desk and it can be conveniently positioned. I would highly
recommend this product.

I'm not sure that I would like pushbutton antenna switching. Especially in
a contest.

I use a 4-position rotary switch to select all four directions of the two
Beverages. (The same principle would apply to more than four directions.)
All four RX directions are within a 90 degree rotation of the switch;
adjacent positions are just 22.5 degrees apart. (And rotary switches are
available with less than 22.5 degrees between positions.)

To its immediate right is a toggle switch that selects either the Beverage
RX rotary switch or the TX antenna. Both the rotary and toggle can be
operated conveniently with just my right hand, while tuning across the
band, etc. with my left. It is a very ergonomic design; if it could be
improved upon, I've never figured out a better way.
 (But I'm listening with an open mind. :-)

A photo of the switching arrangement here can be viewed at
www.w0btu.com/Beverage_antennas.html#more_than_one_way_to_build
Click on the image to zoom.

I think W8JI --and somebody else who copied his design-- has eight PB
switches in a ~2" diameter circle, all barely protruding just past the
panel. Maybe if I had one, I would prefer it over what I built, but I
really don't think so. When my fingers are on that switch, I don't have to
feel around for pushbuttons nor take my eyes off more important things.

IMHO, a rotary switch is the way to go.

Re: Topband: Video Switch for Low Band Antenna switching

[Herbert Schoenbohm]

The early Dynair switches are passive and they only require pushing in 
the old fashion PB snap switches.  The only voltage they use (optional) 
is for switch illumination which was required to show with video monitor 
was connected to a particular source in a darkened control room.  I 
removed all wiring and the 12v supply since it is easy to see in front 
of me which RX antenna is selected.  My only complaint is that during a 
contest one hand (also the one I send CW with) is constantly changing 
antennas.  The design by Gary with the momentary pad is a big 
improvement especially if it has a computer interface selection for 
remote operating.  Right now I can only switch 6 antennas by the remote 
op on the mainland by using IP Power and a bunch of relays in 
conjunction with a DX-Engineering RTR-1

Re: Topband: Video Switch for Low Band Antenna switching

[Tom W8JI]

BTW, besides having to rotate this switch only 22.5 degrees,it turns very
smoothly. I fiddled with the spring tension and lubed it for just the 
right

amount of torque without being sloppy.



In the 1970's, I started with a rotary switch, but didn't like it. I used 
push buttons from a telephone line switch. When the PB mechanical lock 
switches were wired with shielded wire, it worked good enough at least up 
through 40.


In the 1980's, I built a push button box with the buttons like a key pad. I 
hated it. I changed to in line buttons.


When we got seriously into contesting, I built boxes that buttons in a 
circle small enough to be worked with a thumb while resting a hand on the 
box, and a sloped front panel with no cabinet lip to get in the way. They 
have LED's by each button outside of the button circle so a thumb doesn't 
always block the lights.


The actual antenna group selection is on a rotary, which puts any array into 
any ear in stereo, and can lock a primary direction like NE or NW. These 
switches run a matrix that is all passive components, allowing any antenna 
into up to four output channels, and also allows the same antenna to be used 
by all output channels. This is an expandable matrix that could do 1, 2, 4, 
or 8 output channels and as many input ports as anyone wants within reason 
(maybe 30 or 40 is the limit).


I did this with strong push-pull low noise line amps, and it won't overload 
even with my own TX running. I don't (and won't) bridge across lines because 
of IMD and noise limitations. It is real quiet here in winter, so I have to 
be careful with dynamic range.


I have field relay boxes that allow up to two directions to be picked from 
any antenna hub at the same time and the NE antennas are available 
completely independent with as many receivers as anyone wants at the same 
time.


My boxes stay connected year in and year out, through thunderstorms and 
everything, and unless lightning actually hits an antenna (which has 
happened a few times in 15 years) they stay connected and working.

Same here.  I have a set of 6 pushbuttons in a circle with
indicator lights to indicate which one is in use.  They control
beverages at 60 degree azimuth intervals.  It is much more intuitive
where I am pointing than a rotary switch.  I also have
random access, instead of sequential access.  I have a 7th
pushbutton in the center for an omni antenna.  The advantage
of this over a rotary switch in a contest is huge.

Re: Topband: Video Switch for Low Band Antenna switching

[Tim Shoppa]

I've used the K9AY pushbutton RX select switches at W3LPL and they are a
very fine ergonomic solution. Definitely prefer the pushbuttons to rotary
switches.

At home I use footswitches for 1-of-4 RX direction selection on 160M. Very
easy for me to cycle multiple directions after each CQ. Two feet gets me to
4 directions, I don't know that I'd be able to grow the last foot to help
with an 8-circle, but that doesn't matter because I do not have room in the
yard for an 8-circle :-)

One mistake I've made a couple times is changing transmit direction switch,
while transmitting. This was especially likely while I was trying to do 2
different receive antennas or having a conversation with others in the
shack. Didn't blow anything up but maybe I was just lucky! A slight
evolution would be a pushbutton transmit direction selector, that would
lock out direction changes while transmitting (or the other way around).

160M in a big DX-only contest requires much less antenna switching, than a
contest where there are many domestic callers worth points as well as the
DX.

As an alternative, in my opinion the receiving antenna switching capabilities 
of the K9AY 8x2 switch are far superior to any available alternative: 



- eight antenna input ports 
- two independently controlled receiver output ports 
- any antenna input switchable to either or both receiver output ports with no 
interaction and excellent isolation 
- two, three or more antenna input ports can be simultaneously switched to 
either or both receiver output ports

Roger,  as long as the switch is passive and not active it will work 
well for you as unused ports are terminate in 75 ohms.  I use a 12X1 
Dynairs here and they have excellent isolation plus it terminates the 
unused reversible Beverage feedline (which is recommended for greater 
rejection).  I just cut the RG6 minus the VF to multiples of a half wave 
length so the termination at the switch appears on the unused port. I 
prefer this to running voltage out to relays which always seem to fail 
at some point.

SVA-100B for sale on eBay but no real description

of it's functions.

It seems obvious that you can, for instance, switch input 3 to output 
7 but can you simultaneously switch input
5 to output 6? In other words, can you have more than one path through 
the switcher?


Any other ideas on switching greatly appreciated!

Topband: Video Switch for Low Band Antenna switching

[Roger D Johnson]

I've been looking for a way to switch multiple receiving antennas to multiple 
receivers. I know some hams are
using video switchers but info on them is scarce. There is a Dynair SVA-100B for 
sale on eBay but no real description

of it's functions.

It seems obvious that you can, for instance, switch input 3 to output 7 but can 
you simultaneously switch input

5 to output 6? In other words, can you have more than one path through the 
switcher?

Any other ideas on switching greatly appreciated!

73, Roger
