Re: [Elecraft] Looking for a way to switch an antenna input to the KAT500

W2VJN and N3RD from Top Ten Devices are great helpful guys. I have been using their band decoders for decades and we have both operated from the same station in St Croix. I also have a Top Ten 6 way antenna relay box that I only use only on contest expeditions with a single radio. It is small,

Re: [Elecraft] Looking for a way to switch an antenna input to the KAT500

Yup, I did specify "good", not "great" isolation for the Top Ten switches. I'm aware of their limitations. I agree that it's always desirable to have 70+ dB port-to-port isolation if you can get it (and afford it), but depending on the application it's certainly not always necessary. During

The Top Ten box just has relays connecting between the input and one of six outputs. There is no reason that you could not use it in reverse, six radios driving one antenna. I use Top Ten relay on my expeditions automatically controlled by their band decoder which is connected to my K3S. John

I concur with the comments on the Top Ten 2-way switches. I'm using about 10 of them at various places in my SO2R contest station antenna and BPF switching networks. They work well and have good isolation. I'm also using a 6-way for RX antenna switching. It's simply one port switched to one of

Re: [Elecraft] Looking for a way to switch an antenna input to the KAT500

Hi, Yes this looks interesting as does the ones from Dewey. It seems that top ten devices also has a 6 antenna to 1 radio switch. Anyone know if it can operate the other way around? 6 radios to one antenna (kat500)? 73 Tom From: John Simmons Sent: February 17, 2019 5:10 PM To: Jack

Jack, Thanks for bringing this to my attention... it is just what I have been looking for to switch between my main and remote operated stations! 73, -John NI0K Jack Brindle via Elecraft Sunday, February 17, 2019 3:59 PM TopTen has a nice A/B switch with

Re: [Elecraft] Looking for a way to switch an antenna input to the KAT500

TopTen has a nice A/B switch with pretty good isolation characteristics. See: https://toptendevices.com/products/ab-station-selector/ It requires a 12V signal for switching, I believe. Array Solutions also sells some devices that may be

[Elecraft] Looking for a way to switch an antenna input to the KAT500

Hi, I use a Kat500 with my K3 and KX3. However, I have a number of other radios which I would like to use with the Kat500. So I'm looking for a antenna switch that can change inputs in some way based on an electronic signal. The signal can be via serial device, or network doesn't matter.
