My Ham Radio Interests
My name is Alan Schiffman and I am a Semi-Retired Podiatrist

I am married to Lesley for 50 years and have two grown up daughters, Ruth and Stacey, and four grandchildren.

I have been interested in communication and radio since I was 10 years old, having cut my teeth in the 50/60's with Ex WD equipment bought from Tottenham Court Road, London and other emporiums.

I have constructed many projects, receivers, transmitters, QRP transceivers, tape recorders, PSU, antennas and so on

I also enjoy Reading Practical Wireless, QST, Radcom, Historical technical magazines and books, local history-and meccano !!! we never grow up us geezers!

WW2 communication equipment: 19 sets, 18 sets, 38 sets, R109, HRO, 1155, I had 'em all

I also collect CW keys

I am OP on HMS Belfast, most Monday's on PSK 31/FT8

My main interest now is PSK 31/FT8 modes mainly on 80M at around 9.00 pm most evenings. Also occasionally QRP CW around 40/20m

I am active on 20m digital modes and during the day, and most evenings aroung 9.00pm on 40m PSK31/FT8 full power.

Would really like to hear from SWL's I use EQSL, I also frequent the other bands , Pse QSL via Bureau. All printed cards will be acknowledged.
Also now re-kindling my interest in QRP CW, and brushing up the speed, also meteor trails on VHF

I enjoy getting kids to use morse code on HMS Belfast. They send their name in CW and I then give them a certificate

Latest development is a helical antenna, again seems excellent and very quiet

Have since modified original antennas, see QRZ.com


Other Interests
I am interested in writing articles for magazines, ie. Radio Bygones, a 15 part article on printing for the Small Printer magazine-my previous occupation was in print for 30 years, and nostalgic articles-the good ol' days-for local community magazines.

Radio and electronic construction, antenna construction, reading rig reviews

I am now working part time, 73 years old and very active.

I also like classical music, and I share a hobby with my wife, Lesley-we keep tropical fish

I also print mugs as a hobby for radio clubs, events, rallies etc.

This is used in conjunction with MFJ-1025 Noise canceller

I found an article on line re: http://www.hamuniverse.com/joystickantenna.html

Look this up and this was the basis of my many, many experiments.

Here's what I do

See the diagram 'homeconstructed joystick'

I cut two pieces of copper tube about 3/4 inch dia, with a piece of plastic conduit to fit
as a coil former in the centre. Onto this I wound a close spaced coil of separated speaker wire to
fill the plastic former.

Use solder tags and nuts and bolts and join each end to the copper pipes.

Feed at the bottom and use about 1 metre of RG8U coax.
Join the centre to the braid and solder to a tag fitted to the bottom of the copper section.

Now connect the centre of a RG8U lead to the end of the coax joined braid/centre stub and cut away
the outer braid, leaving just the centre conductor connected. The other end goes to a PL259 and the
MFJ 949E ATU (this is the best ATU I have found).A random radial is then run from the earth wing
nut on the ATU, out of the window, and along the ground outside our ground floor flat.
Mine is about 20 feet long.

I then fitted an insulated hook arrangement to the top of the antenna so I could hang it from the top of
the balcony, the bottom of the antenna is only 2 inches above the earth.

The stub/coax lead is then run along the ground, through the window to the ATU

YOU MUST HAVE A GOOD EARTH. I drove 2 feet of earthing stake into the ground,
connected thick earthing wire and run this to the ATU and rig.

Cable clip all leads into the shack to this earth lead.

Put a ferrite ring on all your rig, PSU and PC leads

I use mainly PSK31 so I had to calm the laptop down HI!

Now cover the entire antenna with black PVC tape to weatherproof and ''hide'' it.

If all is OK, you should be able to tune up 1:1 on the HF bands. Tune very carefully and note
all ATU settings.

I have had many great contacts in PSK31, but would be interested in any comments you may have

CONSTRUCTION DETAILS: 3/4 inch tube

TOP SECTION COPPER TUBE 32.5 inches
BOTTOM SECTION COPPER TUBE 44.5 inches

PLASTIC CENTRE COIL FORMER-CONDUIT 210 turns of single speaker wire-pound shops!

Feed at bottom, use radial, and A GOOD EARTH

I have a lot of metal balcony all around, but it still works great.

Again refer to http://www.hamuniverse.com/joystickantenna.html

Since 27/2/2012, I have added a duplicate vertical connected to the original vertical, and this one is lifted to horizontal, forming an L shape arangement.

Many thanks to the author of this great article

Look forward to any comments/improvements
