Hello Jim.

Well= , that sounds an impressive system to me. I think Dave (currently GM3YXM) a= lso uses the ELAD SDR and it works very well.

I have read abou= t the Hafler amplifiers on some of the USA sites, but I didn't realise = they ever appeared in Europe.
If you can manage to get something o= n-air that would be good, hopefully if you have the SDR then you will also = have JT9 / FT8 available too.

My system is limited to about 70= W at the moment as the antenna is fairly high, but it seems to work.
<= div>If I can gain a couple of arms, I will also try to operate crossband to= 80m. After all there are 160+ generating WSPR spots, perhaps they are up f= or a crossband QSO.

CU tomorrow.=C2=A0 BTW, you may hav= e an extra hour for reconnecting the antenna.=C2=A0 15:00 to 24:00 nominall= y !

If I can get the garage s= nug with fan heaters then I will look at patching in the new Hafler 9505 an= d get a bit of QRO going for Saturday from 2pm onwards.

ELAD FDM Duo as a the sig= gen, giving out 630m signals via the 0dM transverter port (this is good fo= r 1khz up to 250mhz!) ,

=C2=A0

The coax then heads out o= f the shack via the old tumble dryer vent (it was our old kitchen) and then= 10 metres across backyard into garage.

=C2=A0

Coax then is fed into inp= ut of a Hafler P4000 and soon to be Hafler 9505 via the input transformer= =C2=A0=C2=A0 h= ttp://www.w1vd.com/Haflertransformers.html=C2=A0

=C2=A0

The stereo speaker output= s of the Hafler are bridged to give about 200w for the P4000 and 400w for t= he 9505 @ 473khz.

=C2=A0

EU spec (220v) Haflers co= me up on Ebay from time to time, albeit rarely.=C2=A0 P4000s are about =C2= =A3250 and I got my 9505 for =C2=A3400.=C2=A0

=C2=A0

The speaker output is =C2= =A0connected to a home brew 4:1 balun to give around 30 ohms impedance into= coax cable from an 8 ohm output=C2=A0 h= ttp://www.w1vd.com/Haflertransformers.html=C2=A0

=C2=A0

This coax runs a further = 5metres from garage to fence, with the coax core being attached to the bott= om of =C2=A0a home brew tapped loading coil.=C2=A0 (about 190 turns on a 6=E2=80=9D soil pipe former).

=C2=A0

The antenna from the tap = point =C2=A0is a 10m vertical (subject to wind!) wire =C2=A0on a roach pole= (lashed to fence with cup hooks and cable ties) =C2=A0=C2=A0with 3 x 30m t= op wires, strung over roof of house to a 10m roach pole at bottom of garden <= u>

The braid goes to earth w= hich is a series of cross bonded earth stakes, oil tank feeder pipe, buried= =C2=A0steel meshes under back patio and block paved drive.

=C2=A0

Resonance and tap point = =C2=A0is measured using a RigExpert AA1000 analyser set for 473khz with a 5= 0khz range initially and then bracketing down to 5khz range (minimum) to get best figures for impedance, reactance & return loss.=C2=A0 -20d= B or more is feasible and I=E2=80=99ve seen -30dB.=C2=A0

=C2=A0

At the shack end, the ELA= D is natively configured as a Kenwood TS480 and is run through HRD5 (last f= reeware version) on a Dell 1749=C2=A0 I3.=C2=A0=C2=A0 For CW/Data I use the excellent DM780 that comes bundled with HRD5.

=C2=A0

The ELAD sets itself up a= s a USB soundcard and I use the =E2=80=9CMCW=E2=80=9D mode to generate CW t= ones via USB so with a ~ 1.1KHz offset.=C2=A0 I tune to 471.9khz and my CW = signal appears at about 473khz.

=C2=A0

The =E2=80=9CUSB=E2=80=9D= soundcard is a little =E2=80=9Cmoody=E2=80=9D to say the least and takes t= he occasional =E2=80=9Cuninstall and re-install=E2=80=9D via control panel = before it starts to show the waterfall display properly.

=C2=A0

The receive signal is fed= in via Ant 1 (SO239) from a long wire.=C2=A0 Ideally I need to build anoth= er loading coil and inverted L for Rx or use a loop or miniwhip as the noise on the longwire is the usual S7 and kills all Dx signals.<= /u>

=C2=A0

Prior to the interstage/h= afler approach I used the vertical for both Tx and Rx with an IC706mk2G (br= oadband modded, easy diode snip).=C2=A0=C2=A0 The IC706mk2g will give about 10 watts out on MF and interfaces nicely with HRD/DM780 too.<= u>

=C2=A0

Using this arrangement, I= regularly got CW/QSOs out to ~ 100 miles and using WSPR, could be spotted = out to 2000km occasionally and 1000km routinely and on the Rx side I could pick up spots from 2000km away.

=C2=A0

The interstage approach p= recludes the use of the Tx =C2=A0antenna for RX so its a new L or a miniwhi= p I think.

=C2=A0

I=E2=80=99ve also used an= IC735 which will generate 5w of RF at 470khz and the RX is suitable sensit= ive too.=C2=A0 An alternate Rx system is a Datong VLF converter which upconverts to 28mhz.=C2=A0 This works very well and is what I=E2=80=99ve u= sed to Rx SAQ and also in VLF experiments.

=C2=A0

=C2=A0

I=E2=80=99ve tried the EL= AD/Hafler arrangement on 8.97 khz and using my inverted L and some daisy ch= ained LF coils been able to hear my 5 wpm CW signal about 500m away using a simple vertical in the car.=C2=A0=C2=A0 I=E2=80=99ve also tried us= ing the G3XBM earth mode approach https://sites.google.com/site/g3xbmqrp/Home/earthmode and= got a similar range.=C2=A0 G3XIZ was unable to detect any signal though at= 2 miles distant, but thats no surprise and my Tx antenna was hugely a compromise.

=C2=A0

I=E2=80=99m not a tech ex= pert by any means (my field of work is paediatric oncology and biotech), ra= dio is just a hobby when work permits!

My local =E2=80=9CElmers= =E2=80=9D are Chris G3XIZ (loaned me and built me no end of kit) , Dennis M= OJXM, Pete =C2=A0MOFMT, Dave G4GIR, Roger G3XBM, Chas, Larry G4OXY (fixed t= he blown Datong!) and back in my early days of MF=E2=80=99ing Jim Moritz M0BM= U.=C2=A0=C2=A0 Sparring with Mal G3KEV has also been great fun, though I ca= nnot hope to compete with his monster station.=C2=A0 A QSL card from EI0CF = is on my pin board=C2=A0 from a CW QSO in 2010.=C2=A0 =C2=A0=C2=A0Stefan, R= olof, Graham, John Andrews, Jay Rusgrove =C2=A0and many others have been a great= help too.

Saturday 30th Decembe= r seems like a good date. A weekend but not new years eve.

Perhaps we could try = to make a QSO or 2 between 15.00 (Sunset in EU) and 24.00 UTC.

Look forward to seein= g a few signals below 475.600.....But if not.=C2=A0 HNY and good dx for 201= 8
