27.560 muppets

Postby NightProwler » 02 Sep 2017, 19:52

I have noticed recently a lot of stations calling CQ on 555 then QSY'ing to 560. This winds me up as they splatter onto 555 if they are strong enough to me. Why the hell dont they move a bit further away? {bnghd}

Rant over :D

It makes no sense but muppets do stupid things.
Chances are if they cause splatter to you on 555, you will cause splatter to them on 560 so just keep calling.
I will not be commanded, I will not be controlled.
n+1 the formula for working out how many radios you need with n being the current amount.

Thats what I cant understand because I hear a few Italian stations doing it when 11M is really active as it has been recently, So they must be getting it from the other stations calling on 555. Odd.

Traditionally the Italians were well known for overdriving amplifiers creating IMD that causes issues to near by frequencies, they often used class C amps on ssb too.

Its not all their fault nor are they alone in thinking pumping 20w ssb into cb amps is ok because it says so in the user manual,
the manufacturers also put ssb switches on class C amps which is almost as stupid as claiming up to 4x what the amplifiers will output with reasonable IMD levels,

there are no specs to meet for cb amps so they can claim anything to lubricate your wallet.

It's always the same stations...1LR001 for one. Being the group president he should know better, but alas he is a bad teacher and a fud TBH. I have told him many times to QSY but he does not give a flying f...monkey about it :/ CB has a bad name anyway without the need for DQRM.

The end is nigh...for 11m anyway as all that will be left on the band will be QRM'ers QRM'ing other QRM'ers :/
Being a ham has benefits...certain religions stay away from me.
Day in and day out swl to same QRM from the same ops but on a different date.
If at first you do not succeed...it's because you never tried hard enough...

If you have better RX that close to T5 then you don't have a very good antenna.

Maybe you need a narrow ssb filter for it!

Selectivity SSB/CW(W)/FSK: 2.7 KHz (-6 dB), 4.5 KHz (-60 dB) is pretty wide nowdays.
Just checked mine rig, pretty old one. 2.3 KHz (-6 dB), 3.3 KHz (-60 dB)

You can quote figures all you like, you're going to get splatter from 5kc's either side no matter what the radio is, old or new.
