> I face a problem with a TenTec Titan 425 amp.
> I got this amp second hand and I have this problems since then
> What happens:
> The amp is hook up to a K2 and give 1500W out with 70 W input that ok!
> Its setup to key via PTT (no full break in)
> I got a delay for 1 second when switch back to RX.
> But this happens only when the amp get power out and a TX for more then
> 1 sec..
> When there is no drive power (or very low ( 0,1W)) or when the TX is
> very short (1-2 dids in CW) there is no delay.
> I have make a small video clip to see what I mean.
> Its on www.xs4all.nl/~pc2a/tentec425.mp4
> Its about 2Mb of size
> (maybe you need Quicktime to see it)
> I do RX/TX on a carrier.
> First I transmit a few short dids and get RX immediately
> Then a bit longer TX and see it takes 1 sec to get full RX
> Then a few sort TX and all ok.
> Then reduce power to 0,1W and a longer TX with a good RX
> For this video the TX input was about 5W and get about 200W out.
> I have already replace the vacuum output relais but still the same
> trouble during RX.
> I have looked at the manual, but can't figure out how the input is switched.
> Any advise?
