Re: LF: running WSPR now on 474.2. approx 20mW erp.

The Decca 5501 module is a better choice on MF to achieve 5W erp out with your aerial

Hi Mal,

 

must be my rubbish aerial!  It's only 10m/30m L and I have noisy laptop psus which also degrades rx perf so I'm a crocodile with small teeth!

 

If I can find quieter psus and get that hafler going then I might do better, but I'm limited by antenna size as neoghbours not overly keen on 12m pole!

 

Got 17000km on 30m but that's a walk in the park

 

Still 1700km for about 20mW erp and compromise antenna is not a bad job

 

 

 

With best regards

So far have been seen out to 1027 km by DH5RAE, 899km by DL6RCN and 807km by LA3EQ.

 

Could do with the Greek chap coming back on air as he was 2000km + from me in IO92ub and I think there's enough headroom to get me there.

 

With best regards
