M1KTA in CT



Not remotely rare as there are loads of CT on the bands.... I will be qrv from CT as CT7/M1KTA/P next week 10th to 16th. Looks like Colin (G8TMV) will be there same week 30 miles west of me.

Rig will be KX3, qrp from the beach but should be up and running 160-6m (no 5MHz!) although expect 20m and 15m SSB mostly.

The KX3 has the new software so will be trying out the Voice Keyer on SSB.

Look for me about qrp freq or ??8 (e.g. 14.188, 14.288, 18.068, 21.288) on SSB and 15 (14.015, 7.015) on CW. I tend to stear clear of qrp freq if looks like there are lots of callers.

If can operate from villa will try data modes.

ZB2 licence for 6m is in progress but not sure will come back in time (no HF possible anyway) for a day trip.

PTO update - From F8DYR

F8DYR updated me that he had also worked on a PTO and used an interesting assembly.

 "I saw on your blog that 3 years ago, you worked on a PTO oscillator. I worked too on this PTO (Same design) and found a useful mecanism to operate it, discarded from an old AM/FM car radio."




472Khz 25W PA

The 25W PA for the KX3 472KHz transverter is a clone of the GW3UEP version http://www.gw3uep.ukfsn.org/25W_QTX/472_25W_QTX/472_kHz_25W_PA.htm so I'll not repeat the circuit diagram.



It is getting a bit cold in the workshop and soldering doesn't work as it should right now so will complete this later but the basic layout is complete.

I have used M3 Nylon screws as stand offs for the horizontal coils. The vertical coil I started it 15mm or so up and glued (hot melt glue) it to the PCB.

My long wire

I was asked could I put up some technical analysis of the long wire...

Here is the plot between 1MHz and 2MHz.


It is a little low and not resonant on 160m

Here is is after the Z11ProII tuner.



As you can see much better.

The 140ft ong wire is fed against a bunch of radials and a fairly decent RF earth but no tuned radials.

Finally got Win-Test running on Linux

Using Wine and a bit of messing about with folder permissions but it works...




I had to recreate my CQWW 160m CW logs in Cabrillo for submission and so I did it whilst at work :-)

It does work under linux.



More HamRadio lists hacked on yahoo

After having a mail box full of more SPAM rubbish this time prescription drugs from Canada I am beginning to get fed up with this happening so I post MY solution ... if you read and use yahoo please do something to stop the problem for the rest of us.

To stop the yahoo email hacks effecting your contacts ... which is all they really want... your email list.

Go to the yahoo webmail login, download the address/contacts to your PC, then install thunderbird email (free and runs in Windows or Linux)... then delete the online address book... they can hack your yahoo account but send nothing to your contacts so we do not get spam from your account :-)


Do NOT select to auto add respondees to your contact list on the yahoo webmail pages and regularly check your contact list is empty.

And change your password to something decent not the same as your pet cat's name perhaps some combination of callsign, locator, a date and a special character (one of these !"£$ etc).

Thanks
