Re: LF: 136.96kHz testing

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Thank you Gary. 

Yes, I hope to give 136kHz a good go considering my small garden and QRP leanings. Last autumn and winter I surprised myself (and others) by achieving credible results on 500kHz with an ultra-simple QRP station. It will be tougher on 136kHz certainly, but I start with low expectations that, with some perseverance, may be exceeded. 

Next on the cards is the transverter design and build. There are plenty of good circuits to grab ideas from, plus I have some of my own. The efficient small antenna will be the really big challenge.

Roger,

Congratulations for Txing a 136 kHz signal, however small, don't let anyone put you off (no names mentioned) we all have to start somewhere. My first 136 kHz Tx was 5 watts & an 80m inverted V antenna, I didn't have any QSO's with that but it was a start.

You will make progress & I will look forward to Rxing your signal in the near future & a possible QSO.

This is the very beginning of my journey onto 136kHz....

For anyone very very close to Burwell, Cambs, JO02DG, I'm putting a QRP 10wpm keyer-generated CW message (later to be changed to QRSS3) out on 136.96kHz CW into my earth electrode antenna. Power from the TX is about 500mW, so ERP is just a few microwatts at most. 

I'd appreciate reports, but be amazed to get any until I start to run some more power into a real antenna.
