Dave, that could be useful, yes. We’re just looking at getting the 2E0KJJ
wouxon up at this end right now… I’ll keep you posted!
Target will be 145.375, unless lo already ocupado.

Ok intresting.
If you want to do some testing I can have a talk through up and running from
Hildenbough up and running in 10mins give me a pair of frequencies and CTSS
code if you want one and I will put it on air this afternoon for testing. I
would happy to run it on net nights when available. Coverage from here not to
bad.

Dave, yes, club premises would be a prime site. as radios are small these
days, perhaps it could be done.
I’m not aware of anything which prevents licensed amateurs using someone else’s
station so long as it’s supervised, in fact, to be best of my knowledge, such
use is explicitly permitted.
This is how I made my first QSO… albeit many years ago, with another chap’s
station.
I believe issues apply where stations are not supervised.

The Wouxon the KV-UV8D hand held also does cross and repeat for about £80 if we
could get away with connecting it to the tri band vertical at the club meeting
room would give good coverage.
But like all the cheap Chinese radios I have encountered they have very narrow
deviation which can't be adjusted.
If a 6m repeater were to go up in the area the club site would be A prime
location.
Not sure if we could do that with the hall owners at minimal cost but would be
good if we could get away with it.
Has the rule on talk through changed? Is it something we now use on our
licence?

Gordon, funny you mention that! Jeremy 2E0KJJ’s Wouxon is basically a budget

Mark,
You need an 8900!

a temporary cross-band managed talk-through for the WKARS net.
A 6m repeater could be of interest in any case, but the only place I can put
one would be in my garden. It’s not an ideal location, but is at least
available!

I have several radios that can cross and repeat and a commercial inband
repeater that works on 2m.
What are you trying to achieve? Are you looking at a potential repeater site?
You need to be mindful of licence conditions when using talk through.
If you are looking at a potential repeater site we need a 6m repeater in the
area.

Dave, looks very interesting - it gives a DTMF remote control of the audio
path, so far as I can tell.
Jeremy 2E0KJJ is presently resident, and has a wouxon quad bander which can,
apparently, do cross-band repeating, so we’re going to give that a try today.
It could be a very simple solution. Maybe.

cross-band working - FT897Date: Sun, Jul 26, 2015 12:02
The FT897 is not capable of cross-band repeating.
To make this work, I think I’ll need two rigs with VOX, one for each band, and
a multiplexer or separate antennae for said bands.
The venerable FT-480r doesn’t have VOX, so it would need additional electronics.
The FT-897 does have VOX, and I have a VX7R, and a couple of Baofeng handies
which also have VOX and multi-band coverage.
So one possibility looks like this:
1. FT-897 set to RX-TX on 433.375, with Vox engaged, and connected to 70cms
antenna; set to 10 Watts so okay for all licence classes.
2. Handy set to RX-TX on 145.375, with Vox engaged, and connected to 2m
antenna.
The audio-out of handy goes to audio-in on FT-897.
The audio-out of FT-897 goes to audio-in on Handy.
Both rigs are set with CTCSS for both RX and TX to something other than
103.5Hz, but very close in frequency to avoid any audible products from
accidental mixing.
The FT-897 forms the link to Bidborough from Otford at 70 cms.
The handy provides a local RX/TX for the Darenth Valley area.
=====
This is a complex setup, and would be much simplified by using a rig which can
cross-band repeat out of the box.
=====
In any case:
At Bidborough, the equivalent is set up. Note that the 70 cms path would need
the same CTCSS setup, but the 2m access would need a different CTCSS from the
Darenth Valley end to avoid opening up both ends simultaneously.
Clearly this would only be up with the operators present, so we’d use it for
Nets, and then take it down.
For this approach to work, all stations would need to be able to reach one or
other end of the 2m access points for both TX and RX with adequate S/N, or
access the 70cms directly, but that would require being able to access both the
Sevenoaks and the Bidborough stations simultaneously.
The approach does seem to be fascinating, involving using radio to do the same
kind of thing which echolink is doing using the internet.
thoughts?
