[Elecraft] 6 meters Newbie

[W8JH]

Thanks Lew, I appreciate the info.

 

I don't have the FM filter but I can set up my FT100 on the mobile for 6m
and see if that hits one of the repeaters.  From there I might be able to
set up a sked on 6m SSB for the K3.  Thanks for the idea!

 

73,

Joe, given where you live, in northern Ohio, you could go for days without
hearing anything on 6 meters.  I live in the Los Angeles area, and I
sometimes just tune the K3 to 50.125 (the SSB calling frequency) and listen
for activity while I'm working from home.  There are three or four guys (in
a metropolitan area of 8 million) who pop up on the band every day calling
QRZ to look for sporadic-E contacts, and on some days, that's about it.
When Sporadic-E opens up, it can get real lively. 

You can check your rig's performance if you have any 6 meter repeaters in
your area, but you'll need a vertical antenna (I use a 6 meter J-pole),
since all the FM activity on 6 meters is vertically polarized, whereas most
SSB activity is horizontally polarized. (However, some LA area ops work SSB
with vertical polarization).  The 6 meter FM calling frequency for simplex
is 53.600 mHz. 

there is a 6 meter repeater in Detroit (53.94 output, 131.8 PL), and one in
Toledo at 53.65, 103.5 PL). 6 meter repeaters are -.5 mhz offset for input.
I don't see any listed in the repeater guides for Cleveland.  You might try
to hit those machines to test your rig, if you have the wide filter
necessary for FM transmission with the K3 and can put together a vertical 6
meter antenna. If the "custom" in northern Ohio and Michigan is to use
vertical polarization for SSB (as some ops do here in LA), then you REALLY
need a vertical antenna, since polarization really makes a difference on 6
meters. Cross polarization can result in a loss of as much as 20 dB in
signal strength, which could pretty much explain why you're not hearing
anyone with a horizontal antenna (if the local ops are working SSB with
vertical polarization).  If you can hit one of the local 6 meter repeaters,
ask any operator you reach what the local practice is for SSB. 

If you want to get serious about 6 meters weak signal (SSB), invest in the
Elecraft PR-6 pre-amp designed for that band. It's worth the cost for its
performance.
