Re: LF: TA ... last night

Hello Jay

Thank you to made this event possible. The transmitter we are using was built in 1999 and it is still equipped with a Vackar-VFO (6.8 MHz divided by 50). I will replace it by a DDS after the Operation in Sottens. For QRSS10 its stability is at the limit. We can't use it in lower modes. Despite this, the heavy drift at start up is a mystery. May be we touched the dial unintentionally. 
There is also a problem with overheating of the LPF. I have to build it bigger, with a cooling fan.

I don't know yet, if somebody will activate the TX next weekend, I will be busy Friday and Saturday evening. But to get earlier on the air would certainly help to find operators ;-) 

So far we have been lucky with the weather condx: In the past weeks it was dry and unusual warm for the season. No rain, no snow. This may change now. Hope we don't get the thunderstorms you had. The Tower is isolated from the ground and there is only a chocke on one leg to discharge the static build up when in use. Every time we go to the site, we have to open five heavy blade-switches, one for each leg and one in the shack - in summer it must be terrible.

Your 40m signal was not strong over here and we lost you almost in the hick-hack of the contest. 

Thanks again for your support and your patience. 73 de Toni, HB9ASB

Thanks again for the FB QSO!

 

A couple notes from last night in case you're planning more T/A activity ...

 

HE3OM was quite strong here right from first key down so an earlier start time would be appropriate. Between this weekend and next sunset changes about 8 minutes. Recommend a start time 1/2 to 1 hour earlier - longer if you can manage it. A number of years back I received Brian CT1DRP as much as 1-1/2 hours before local sunset. While it wasn't a regular occurrence it did show what's possible. Your signal is the strongest I've seen from EU so who knows what limits can be pushed.

 

Signal strength steadily deteriorated as the evening progressed as I've noticed this on other EU signals this season. Earlier is better.

 

On initial startup there was a quick drift down in frequency from 316 to about 310 where it stabilized for the rest of the QSO. On slower QRSS modes this could drop you 'off screen' on a grabber that displays only a narrow frequency range. Assume that was just the equipment warming up. 

 

Thanks to all involved for getting HE3OM on the air - the effort is appreciated!
