[RTTY] Some Advice Needed

[John Barber]

Hi Barry,

Good to see you will be back on RTTY.

The FL2100Z works fine on RTTY but don't expect it to run flat out for a
RTTY contest. I think Yaesu quoted 400W DC input for RTTY so maybe 200-250W
out. The 572B tubes are around 150W anode dissipation each so 300W total;
that's always a good guide as to maximum continuous output. Derate it a bit
for RTTY contest use.

I just repaired a 2100Z for a friend who pushed too hard in CQWW RTTY. 2
tubes and a few other bits. He switched to a FL7000 and blew that up too!

Hi All

 

After a lengthy absence I am starting to get organised for a return to the
airwaves, and specifically to get active on RTTY again
.

 

To sum up, life intervened and I sold my Kenwood TS-870 and TL-922 amp about
a year back, reducing my shack to a Yaesu FT-847 and a little RM KL-500 300W
amp (which has subsequently died).  This setup just did not work for me, and
I faded right out of radio for several months.  However in recent months my
fiancée has been encouraging me to get back into the hobby (I am a very
lucky guy!! :)  ), so I sold the FT-847 (and a whole lot of other bits and
pieces) and got myself an immaculate Kenwood TS-590S (with TCXO and VS-3
fitted), am in the process of sorting out my antennas and am shopping for an
amplifier – and this is where I need some advice/expertise!

 

Being in Darkest Africa, finding such a thing with my VERY limited budget is
tricky. New amplifiers are simply out of my reach – to put it in
perspective, at our current exchange rate my monthly disposable income
equates to around $500 (our currency has lost more than 40% in value over
the past 2 years).  This leaves me looking at something like a Yaesu
FL-2100Z
.

 

I can get a FL-2100Z with brand-new 572Bs, at a price around the top-end of
my budget. I am looking for advice or comment – is this amp any good on
RTTY???

I know that it is no TL-922, but at least it will fit in my tiny shack area
– and is available here!!
