I forgot to mention also Op Swapper from TopTen devices. It is similar
with 2S1 but in much better price. See
http://www.qth.com/topten/os.htm
Acom 2S1 and TopTen OpSwapper shares the same antenna to 2 radios with
interlock to radios.
4o3a 1a2r switch shares 2 antennas to 2 radios (not interchangable) with
interlock
and ea4tx interlock just interlocks 5 radios as you want (software
adjustable) (you need to switch the antennas, amplifers, etc)
All devices work easy with big Yaesu and Elecrafts while you need an
external relay for Icoms and Kenwoods (correct me if there is a kenwood
with inhibit jack)

Also there no LP category. Only HP, so M2 is not a wise decision.
I know 3 devices:
1) 4o3a
http://www.4o3a.com/index.php/products/station-automation/lock-x/
and for inband use
http://www.4o3a.com/index.php/products/antenna-switchers/1-amp-2-radio-switch/
2) ea4tx
http://ea4tx.com/en/ea4tx-interlock/
3) Acom
http://www.acom-bg.com/products/xcvr-commutator/acom-2s1-automatic-xcvr-commutator
Acom and 2nd 4o3a are for inband use. With Acom you can share the same
antenna, with 4o3a you need 2 antennas (better but you need one more
ant).

Oh .. and about operating on the same band..
You use LP.
If you have separate antennas for each radio, you should have no
problems.
If you want to share the antennas, I do not know of any commercial
products
for the use you describe.

For M2, you do not need a PTT interlocking device if you use two
radios.
If you use two radios per band, then you need a PTT interlock for those
two radios on each band.
If you use a third radio for 3rd band multipliers, you need an
interlock.
This 3rd band interlock can be complex, depending on how you want to
operate.
But, for a M2 station with just two radios, one for a band at a
time, you
do not need an interlock.

Hola,
I'm planning to operate M2 LP, the oncoming contest season.
I do have two WX0B passbands filters from my previous SO2R setup.
-Only two radios will be used.
and
- Very simple antennas setup on a city lot:
Log periodic Cushcraft ASL-2020
Vertical tribander Force13 VR-3
Twin Slopper Alpha-delta DX-A
Is there any summary related to options available for locking
devices to
prevent two radios to operate in the same band? I do not want to have
burned front ends.
Preferably, I would like to build it.
I appreciate the feedback
