K4ZSR’s Xiegu X6100 Field Kit

by Zach (K4ZSR)

My primary portable radio station is based around the Xiegu X6100. This was the first HF transceiver I bought after getting my ticket, and I have taken it on well over 100 POTA and SOTA activations across ten countries. Over time, I have learned what does and does not work for me and my operating style, and my field kit now has exactly what I need.

I have used several different packs to hold my portable radio gear, but my current favorite is this Quechua NH Escape 500 from Decathlon (I bought mine in Romania, but you can order them online). While designed as a laptop bag, this pack has all the features I need to carry for radio gear: full-opening main compartment, padded laptop/tablet sleeve, waist belt, good internal organization, and extra room. My field kit always stays in this bag, unless I am going on a long hike or camping.

The heart of this field kit is a fully self-contained station in a semi-hard side case (meant for a portable projector). As long you have a tree or other antenna support, everything you need is in this case. I always have more equipment with me, but this is the bare minimum. Two modifications I made to make the kit smaller was replacing the stock mic coil cable with an ultra-slim CAT 6 cable, and making a 6-inch power cable.

  1. LTGEM Hard Case
  2. SP4 POTA/SOTA Paddles
  3. Xiegu X6100
  4. Panasonic Earbuds and Moleskine Cahier notebook
  5. K6ARK 20w EFRW Antenna (laser-cut winder, 26g PTFE wire)
  6. GPS/GLONASS Receiver and USB cables for digital modes
  7. Bioenno 3Ah Battery
  8. “QRP” sized Weaver 8oz bullet throw weight with braided fishing line
  9. 10ft RG-316 Feedline

Since I do no always have a tree handy, and you should never be without at least two antennas, I always have a mast and an antenna accessory pouch with me as well.


  1. DIY spike base, tent stakes, and guy lines for mast
  2. K4ZSR 20m EFHW “Credit Card” antenna
  3. SOTABeams Carbon-6 Mast
  4. Solognac medium organizer pouch – purchased in Europe
  5. Miscellaneous antenna gear (compass, wire ties, extra stake, bungee cord, carabiners, etc)
  6. 80m extension for 6-band EFHW
  7. K4ZSR 6-band EFHW (40-10m, with 30 & 17m links)

Adding my Microsoft Surface Go 2 tablet for logging and running WSTJ modes, and my field kit comes in at just over 9 lbs (ignore the scale, the tablet case was empty in this picture).

If I am going to be operating in an accessible and open area, I may bring my vertical whip antenna system. This is one of my newest additions, I assembled this antenna over Christmas 2023. I wanted a ground mount system for a 17 ft whip antenna, but I needed it to pack down relatively flat to be able to carry easily in a back pack. My solution was a modular base designed like a pedestal mount used for soccer flags. Even in somewhat soft ground, this base is incredibly stable despite the small size of the ground spike.


  1. Wolf River Coils 17’ SS whip
  2. 25ft RG-8X coax
  3. Tent Stakes
  4. Wolf River Coils Sporty 40 coil
  5. Faraday cloth
  6. K4ZSR ground spike vertical antenna mount

Assembled, the mount is inserted into the ground until the disk makes firm contact. The spike and the 3/8-24 mount are removable for packing, and the aluminum boss has 4mm holes for inserting banana plugs to ground the faraday cloth, or to attach ground radials.

Here is the antenna system assembled and in use at K-2949, Harpeth River State Park.

My true passion for amateur radio is portable operations, and as I add to my collection my field kits will grow and evolve. The most important lesson I have learned operating portable is to have simple, durable kit that you are very familiar with. That way when the situation is different than expected, or conditions change, you are prepared to adapt and overcome.

    1. Thanks, Matt. I haven’t used it in super windy conditions yet, but it seems very stable when I raise and lower the whip. I will try and set it up next time we have a wind storm and report back.

  1. I have a MC750 vertical for my POTAs. It has spike mount also, works well. Have found many parks have soft soil for about 3 inches then very hard, takes some work getting the spike into the ground.

    I also have umbrella stake with spike for my 20ft portable flag pole I use for either my 40m OCFD or end fed wire.

    1. Concur on the ground conditions. I often find rocks below the surface, but the good thing about my mount is the spike is 1/4″ SS. Being small, it is much easier to get into the ground, even if it is a bit rocky.

  2. Hi Zach,
    I also use the X6100 as my POTA Radio along with the Wolf River Coils 17.5 ft whip and Sporty Forty. I have been using the WRC tripod on aluminum window screen, but plan to switch over to Faraday cloth in the Spring as it will make the system much more portable as I would like to try some bicycle mobile. The WRC system is very robust and also works great in a mag mount on my truck. You have done an excellent job creating your kit and I’m sure others will benefit from your knowledge. I love the X6100 and now have over 75 activations with it. It is a very underrated radio and so much better now with the recent firmware updates. With some parks not wanting wires in the trees, The Faraday cloth is a lifesaver and no radials for other people to trip over. I am not sure your experience, but I do not need a tuner for 20M and only do a touch up if required on 40M I like how you have used tent pegs to hold it flat. Thank you for a great posting.

  3. Thanks for the kind words, Tim.

    I really like the faraday cloth. I went straight to that, never using window screen. Other than blowing in the breeze, the faraday cloth is a great solution. I have found the same in terms of matching: nearly flat SWR 20-6, with 40 being usable (average 1.8:1). I think if I added even a couple wire radials in addition to the cloth, my SWR on 40m would be better. I need to try that soon.
