Party tickets sales are rising and all the "noise" in the bands and in the URE forum is making hams here to try MF. Most of the time only to discover that their pricy Icom is almost deaf on MF and/or the local noise is over S9++ But there are some few which takes this as a technical challenge and improve their Rx to the point of receiving the first signals. And then they can't stop there ;-) The PA is a nice and simple design by GW3UEP http://www.gw3uep.ukfsn.org/25W_QTX/472_25W_QTX/472_kHz_25W_PA.htm I replaces the BS170s on U3 with an ICL7667 as you proposed for the RasPi. This povides more than enought signal for the PA Mosfet, actually an IRF510. Powering it at 14V got a 6 times increase in antenna current, which provided the spots out of EA last saturday night. This links to some pictures of the PA https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/MF/CAM00386.jpg https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/MF/CAM00392.jpg https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/MF/CAM00398.jpg Yesterday I tried it at 24V. Little difference. Got 8 times antenna current. But tried to fine tune the loop to squize some more power. It detuned for a moment and that was the end of the mosfet :-( No mercy at 24V. I have learned to tune at low power and then increase. Should be interesting to add a current limiter too. May be you can suggest other ways to protect the PA and make it fool proof An MF cirulator perhaps ;-) I got 0.9mm enameled copper wire for the coil to test the vertical. But first of all would need to run the loop with PA for some time to get a clear idea of which is the performance and then test the vertical and then check the difference There is not only MF here. Have other circus rings running different shows, like VHF Opera, microWaves and coming soon some NanoWaves too. And some of the dwarness are getting too big ! https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/Basculante/CAM00399.jpg https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/Basculante/CAM00403.jpg PS: CT1JTQ seems to be an Italian living in south Portugal 73 de Luis EA5DOM ________________________________________ De: owner-rsgb_lf_group@blacksheep.org [owner-rsgb_lf_group@blacksheep.org] en nombre de DK7FC [selberdenken@posteo.de] Enviado: lunes, 25 de mayo de 2015 1:59 Para: rsgb_lf_group@blacksheep.org Asunto: Re: LF: EA5DOM vertical Hi Luis, I can see another new EA stn now. EA3KU just received a few stations. You need to run the party down there and provide a decent signal, also for us in the far north :-) How about your progress on the vertical? And can i see your PA design? :-) 73, Stefan PS: I just tried to contact CT1JTQ for a project on MF :-) (Saw him beeing active a few hours ago in WSPR (on 10m though)) Am 24.05.2015 09:59, schrieb VIGILANT Luis Fernández: > Hi Graham > > Right !.
