Two radios & one antenna

[Bob Wehking]

Now that I am using my K2, I need to know what is the best way to switch my antenna from my Icom 756Pro to my K2? Will an Alpha Delta 2 position switch be sufficient to isolate the font ends of each radio or do I need something else?

That switch is rated at greater than 60 dB of isolation up to 30 MHz.
With 100 watts output, that would mean that no more than -10 dBm would
reach the input of the "off" rig.  While that is enough power to cause
nonlinearities on a received signal, it is well below the level at
which any front-end damage would occur (I suspect that the T-R switch
of the radios offer similar isolation).  I have used the similar
MFJ-1702C switch with a K2 and TS-570D with no problems.

I use an MFJ two position coax switch. I've never had
a problem.

Howdy Bob:

Go with the Alpha Delta switches...I have used several of them over the past
8 years without any problem at all.

I had previously used a couple of MFJ antenna switches and they were built
like junk and I had problems with them.  I bit the bullet and got the Alpha
Delta's and love them....very well built and they last.
