Leaving the Shack and operating somewhere outside can be fun – Often it gives you a better chance of hearing something distant thanks to the low noise-floor and extra space for decent/resonant aerials. I was quite late getting into “/P” myself – it wasn’t until around 7 years after I got licenced that I began to gather a “portable” kit together.
Despite the obvious requirements of a radio, aerial and a power-source – it’s amazing what else you find yourself needing!
At my disposal are an Icom IC-7300 HF/6m transceiver plus a Yaesu FT-857D for excursions onto VHF/UHF.
This first picture shows a summer /P setup: IC-7300 plus LDG auto-ATU and Bencher paddle. Notice the headphones – very useful when it’s windy or for when there are many callers!
Power, depending upon radio in use, is via a 32Ah lead-acid battery. The 857 is sometimes combined with an LDG YT-100 auto-ATU. Aerial-wise, I often use a linked-dipole for 40m/30m/20m/17m. A length of 300-ohm balanced feeder is also used if I wish to string-up a frequency-agile Doublet. I have recently added a reel of 4x 10m counterpoise wires if I fancy trying a 40m/30m 1/4-wave vertical.
The Main /P Kit-List :
A Really Useful Box – 21L capacity, for transporting most of my /P kit when I’m in the car – it also serves as a radio stand when I operate from the passenger seat during the winter: The box sits on the driver seat allowing the radio to be at a more natural operating height.
Icom IC-7300 HF/6m Transceiver
Purchased June 2018 to be my main /P radio – great RX filtering, the spectrum display/waterfall and voice-keyer make it an attractive solution for a /P “session”. There’s also an LDG AT-200proII auto-ATU.
FT-857D HF/VHF/UHF Transceiver
All bands, all modes etc – It offers “digivox” so I can use PSK/RTTY/JT on my laptop using a simple 3.5mm to 6pin mini-DIN lead (no PTT faffing). I intend to add the Collins narrow CW filter for 2018’s /P season. There’s also an LDG YT-100 auto-ATU.
7Ah, 12Ah or 32Ah Lead-Acid Batteries
Power comes from either (or both) of these – I get around 2-3 hours of SSB operating @ 100-watts with the 7Ah “brick” before significant voltage-drop occurs. I was able to flatten the 12AH after a busy 4.5 hours of use with the 857. The newer 32Ah battery is for longer operating days.
10m Telescopic Fishing Poles : Standard and “Travel” aka: DX-Wire/SOTAbeams
It’s 115cm closed and a few cm short of 10m when extended – The dipole centre can sit on top of the 2nd section making the apex of my 40m Inverted-V around 9m up. It’s also possible to run a 40m 1/4wave vertical up the side with a little winding on the lower sections.
Also works great as a simple “end-fed” vertical with a few radials. This particular one came from SOTAbeams (just over £30). I’ve also got one of their 10m “travel” poles (originally from DX-Wire). I use 1m lengths of “steel corner” aka: angle-iron to support the pole in the ground which can be purchased from B&Q here.
Kit-Bag of Assorted Stuff
This bag contained a modem/networking kit and it makes a great way to transport my “consumables”. There are little pockets for a dipole centre, insulators plus a zipped pouch for cable-ties and coax adapters. A further compartment houses my ground-pegs and yellow support cords.
I would say that this bag is “just right” for what I use – but it’s been filled with other random bits for those occasions when you try something new or a fellow operator needs to borrow something – These /P Kit Bags from Ham Goodies will probably replace it when the zip finally gives out!
There’s a set of PowerPole leads with both spade and croc-clips which connect the IC-7300 and FT-857 my various batteries.
Anderson PowerPoles are a great connector as they prevent you from connecting the polarity incorrectly. The plastic shells are common, and you can buy metal crimp/solder contacts in various ratings.
For operating comfort and convenience, I have a Yellowstone Executive Camping Chair (£12 Amazon) and a Regatta Matano Table (£23 Amazon) with my previous bike/QRP kit consisting of a folding chair (£6, CPC) plus a low-level table (£10, CPC) – A snug fit into the panniers, but was better than sitting on the ground! For the car, a 21-litre Really Useful Box is used to carry other bits and pieces, such as hammer, coax, 40m filter etc. This setup is shown in the picture below…
Keeping the sun off me, and perhaps acting as a shelter if I should ever get caught in the rain – The DD Solo Tarp (2.8×1.5m) comes highly recommended.
I use some cheap interlocking poles and the 4 supplied guy-lines plus pegs to secure it in this arrangement. The tarp can also be configured in a variety of other ways thanks to the numerous holes/loops.
Lately, I’ve been securing one of the shorter sides to my open hatchback and supporting the other ends with the metal poles: This makes a nice operating environment as I’m close to the car, in the shade and I don’t have to keep adjusting it to keep the sun off me (and the equipment)!
A home-made transportation and operating enclosure for the FT-857D, ATU and battery – this has its own page – here…
This was picked-up from Maplin as it was on special offer at just £19.99 (reduced from £37). It comfortably takes the FT-857D, LDG YT-100 ATU (under the radio body) plus the MH-31, DC cable and a 7Ah SLAB. I can use the lid as a wind-break and simply attach the display and prop the radio+tuner onto the lip of the case and start operating. There’s plenty of clearance at the back of the radio to get plugs connected.
40m Bandpass Filter
An essential item for multi-station operating. I purchased this one as part of a “group buy” in April 2016 – see my blog post “We Have Filters!” for details.
This style of headset is great not only for ease of transport but they are comfortable for long-term use. Sure, they don’t attenuate as much sound as closed-ear headphones but at least they don’t annoy you after 30 minutes use!
This is the typical setup for a /P adventure:
- Linked Dipole for 40/30/20/17m … plus Inverted-V wires for 40m and 20m – also workable on 15m SSB
- 2m Slim-Jim made from 450-ohm ladder-line
- 40m Doublet (10m per leg) – fed with 17m of 300-ohm feeder
I use 2 runs of RG-58 coax (12m each) and, depending upon location, either use a screw-in base or tie my 10m fishing-pole to a fence/post. It often has only the 40m wires but, when adding the 20m set (at right-angles), it becomes a self-supporting HF+VHF arrangement. Sometimes I feed the 40m wires with 17m of 300-ohm ribbon to give me a more “all round” HF Doublet – For this, I have a home-brew 1:1 Choke/Balun.
