Topband: ts870s on low band

[Thomas Damboldt by way of Bill Tippett <btippett at alum.mit.edu>]

Hi topbanders,

I am using a TS-870 on topband in a very high noise urban environment (S9 
in 1 kHz and AIP off) and I am quite happy with it, although I could not 
compare it with other (better?) equipment.

Just want to report on my experience with the Inrad filters and PIN diode 
improvement (WWW.GARANT-FUNK.DE in German). There is no strong transmitter 
in my area, so actually there was no need for this improvement, but I 
thought the noise problem would be a little less due to improved 
selectivity and linearity. In short: there was no difference in 
performance, so for this kind of application the expenditure it is not 
justified. In fact there is a disadvantage which I can not explain: in the 
50 Hz bandwidth very weak signals are distorted which is not the case in 
the original TS-870.

73 and HNY
