The Shack of LA8OKA


CQ WW 160 m Contest February 2005.

ICOM IC-PCR1000 Communications Receiver

Frequency coverage:

10kHz -1300 MHz

Modes:

WFM, NFM, AM
USB, LSB, CW

Memory channels:

1000 per memory files, number of memory files is only limited by the computer.

This is one of the computer controlled wide band all mode receivers I have. The receiver is very versatile and offers reasonable performance on HF (but not the same selectivity as the WiNRADiO WR-1550e) and works very well for reception of radio signals in the VHF and UHF range. The software is easy to work with, but lack the possibility for plug-ins. It is one of very few wideband receivers that have a 50 kHz IF-filter, and because of that I use this receiver for reception of weather satellite images.

For more information about this receiver visit the ICOM IC-PCR1000 page at ICOM.

Memory channels:

256 alphanumeric memory channels with 8 frequencies each. A total of 2048 frequencies can be stored.

This is one of the best portable world band receivers ever made, it have reasonably good performance on LW, MW, and SW. I use this receiver for casual listening and when I'm travelling and for FM-DXing. This receiver also have an excellent RDS decoder. I have also used this receiver for MW-DXing from time to time.

 

SONY ICF-SW7600GR World Band Receiver

Frequency coverage and mode:

150 - 30 000 kHz  (AM, S-AM, LSB, USB)
76.0 - 108.0 MHz (WFM)

Memory channels:

ACCESSORIES

 

ICOM IC-2KL

ICOM IC-2KL is a 500 Watt Solid State Linear Amplifier who I use occasionally on HF when I need that little extra to get through in a Pile-Up.


Sommerkamp SLA-50

Sommerkamp SLA-50

Sommerkamp SLA-50 is a 50 Watt Solid State Linear Amplifier for 2 m and 70 cm which I use occasionally when I need that little extra to get through in a Pile-Up.

 

ICOM IC-AT500

ICOM IC-AT500 is a fully automatic antenna tuner. It have presets for all bands which makes tuning unnecessary and changing band is just a matter of seconds. The IC-AT500 can handle 500 Watts and I use it both when I'm running the IC-2KL.

 

MFJ-948

The MFJ-948 is good versatile manual antenna tuner, it can match just about anything.

 

MFJ-971

The MFJ-971 is a manual antenna tuner, and is mostly used for portable operation.

 

ICOM AT-120

ICOM AT-120 is a automatic tuner that can tune almost anything. I control this tuner from my KENWOOD TS-2000X via the LDG K-OTT interface.

 

LDG AT-100Pro

LDG AT-100Pro Auto Tuner

LDG AT-100Pro is a tuner which works great with any transceiver.

LDG K-OTT

LDG KENWOOD One-Touch Tune Interface is the little miracle matchbox that let me use my ICOM AT-120 and my LDG tuners with my KENWOOD TS-2000X and TS-590.

Check out this site for more information about the LDG K-OTT:
http://www.ldgelectronics.com/c/252/products/12/38/1

 

LDG RT-11 Remote Tuner

LDG RT-11 is a nice little tuner, which I bought as a Kit and built myself. I use my RT-11 mostly for mobile or field operations.

Check out this site for more information about the LDG RT-11:
http://www.ldgelectronics.com/c/252/products/7/31/1

SGC SG-237 Smarttuner and the SGC Stealth Kit

The SGC SG-237 Smarttuner is even smaller than the LDG RT-11, and also much better. This tuner has become my new favourite tuner. No more fussing around with interface between the tuner and the transceiver, just apply 12 VDC and RF and it tunes the antenna.

I bought this tuner with the SGS Stealth Kit which includes ropes and wire for making our own antenna on the go.

LOWE PR-150 Preselector

I bought this Preselector primarily to enhance the receiving capabilities on HF with my
YAESU VR-5000 Wideband Receiver.

MFJ-959B Receiver Antenna Tuner with Preamplifier

This is a antenna tuner used for reception to enhance the received signal strength.

MicroHAM microKEYER II

microHam microKEYER II

This is a combined USB rig control interface, a USB soundcard, a RTTY and CW keyer. It is probably the best interface there is around, and it can be configured for almost any kind of amateur radio transceiver.

For more information see this link: http://www.microham.com/contents/en-us/d126_MKII.html

microHam microKEYER

This is a combined USB rig control interface, a soundcard interface, a RTTY and CW keyer. It was probably the best interface there is around when it came, and it can be configured for almost any kind of amateur radio transceiver.

For more information see this link: http://www.microham.com/mk.html

USB Interface III

microHam USB Interface III

This is a combined USB rig control interface and a USB soundcard for use with all soundcard digimodes. I bought this because I wanted something smaller and lighter to go with my laptop without limiting my digimode capabilities.

 

TNC-X Terminal Node Controller with X-Track APRS tracker and X-Digi digipeater.

I have 2 of those TNC's. I use one of the TNC-X's with the X-Digi digipeater daughterboard and can configure the TNC-X/X-Digi for use as a portable digipeater when necessary. The other one is primary used in the shack as an interface between one of my 2 m transceivers and the PC. I also have the X-Track APRS tracker daughterboard which I can install when necessary.

For more information see this link: http://www.tnc-x.com/

Tracker2 APRS Tracker and Digipeater

This is a great little device, it doubles as a tracker and as a digipeater, making it perfect for mobile and portable digipeaters. It can be used as a KISS TNC as well.

TinyTrak3Plus APRS Tracker

I use the TinyTrak3Plus for APRS tracking.

For more information see this link: http://www.byonics.com/tinytrak/tt3plus.php

OpenTracker+ APRS Tracker

I use the OpenTracker+ for APRS tracking, I have 2 ea. OpenTracker+. The OpenTracker+ is as great little tracker, and it's actually my favourite tracker because it can output APRS stations as waypoints on my GARMIN GPSmap 60CSx GPS Receiver.

For more information see this link:  https://www.argentdata.com/catalog/product_info.php?cPath=22&products_id=65

GARMIN GPSmap 60CSx GPS Receiver

I use this GPS receiver for APRS, trekking, mountaineering, car driving and just about everything you can use an GPS receiver to do.

For more information see this link: https://buy.garmin.com/shop/shop.do?cID=145&pID=310 

GPS Receivers

I own a little bunch of GPS receivers, most of them I use for APRS. The GPS to the left is a GlobalSat BT-359 Bluetooth GPS that I use with my laptop PC and my mobile phone. The GPS in the middle is a GlobalSat BR-355 GPS  and the GPS to the right is a Deluo GPS, I use both of them for APRS. Both can also be used on my laptop PC.

Instruments and tools

Every radio amateur shack needs some tools and measuring instruments, here is a collection of some of my tools.

Oscilloscope

The oscilloscope is the most versatile instrument for measuring electronic signals.
My oscilloscope is a OWON PDS8202T 200 MHz 2 GS/s.

Multimeter

Every shack needs a multimeter, I have several multimeters, but my favourite is the Agilent U1253A.

MFJ-269 HF/VHF/UHF SWR ANALYZER

This is a very versatile SWR/Antenna analyzer. This instrument is really helpful when I’m experimenting with antennas.

Check out this sites for more information about the MFJ-269 HF/VHF/UHF SWR ANALYZER:
http://www.mfjenterprises.com/products.php?prodid=MFJ-269

MiniVNA

The mRS miniVNA is a handy instrument for measuring antennas, cables and filters. But the documentation is quite poor, the USB driver is unstable and the various software that are available could have been a lot better, but when it works it gets the job done.

GSV3000

Power Supplies

Power!! It’s always necessary with a power supply to power the amateur radio station. Above is a selection of some of the power supplies I use. The Samlex SEC 1223 is a switch-mode power supply. The SEC 1223 is excellent for powering 100 watt rigs when travelling. The Watson Power Mite is also excellent for travelling, it's smaller than the Samlex SEC 1223, and it have voltage and ampere meters as well. The Velleman K7200 is a power supply that I bought as a kit and built my self, it is a great lab power supply for all radio amateurs who like to experiment with electronics. The Daiwa PS-30XMII and Diamond GSV3000 are standard power supplies. I guess most radio amateurs have a similar power supply in their shack.
