My X6100 arrived this week and I did notice some noise on the receive audio when wearing headphones. It shows up as a 1000 Hz tone with a few harmonics and it’s loud enough to make the audio a bit fatiguing to listen to. The good news is that the noise disappeared when I added a mini line isolator between the rig and headphones. It also removes the hiss!
I thought you’d be interested since you have the same rig so I recorded a short video that illustrates how well the isolator works.
You can see the 1000 Hz carrier and it’s harmonics appear in the audio spectrum when the line isolator is removed. You’ll also notice an increase in the audio noise floor.
X6100 Internal vs. External Speaker
I also uploaded a short video that shows how the X6100 audio sounds with the internal vs. external speaker.
Note that the ICOM speaker requires a mono-to-stereo adapter to work with the 6100. Plugging the speakers mono jack directly into the rig wont work.
The camera mic doesn’t do justice to how much better the rig sounds with the external speaker, but it should give you some indication.
I like how the isolator is such a simple solution and imagine it could help other radios with similar issues. Often these noises and harmonics come from display noise. Also, your video certainly shows the improvement using an external speaker on the X6100! Thank you for sharing!
So far this winter has been a challenge in terms of activating summits. For me, at least.
Between my busy schedule, family life, and the weather, it’s been difficult to make the stars align. Activating a summit, in general, requires much more time than activating a park. At least, where I live.
Summits tend to be much less accessible and time-consuming than, say, a state or national park. Besides getting to the summit trailhead and hiking it, there can be quite a bit more research in advance including reading previous activator notes and mapping out the true summit location.
SOTA (Summits On The Air) activators (depending on their location) often have extra incentive to do activations during the winter because many of us can accumulate “bonus points” for summits above a certain height during the winter months.
As I’ve mentioned before, I’m not a numbers guy and honestly couldn’t tell you, for example, how many parks I’ve activated this year. But it would be awfully fun to eventually achieve “Mountain Goat” status in the SOTA program. It requires 1000 (!!!) points. Many of the summits where I live range from 1 to 10 points each. Each summit can only count once per year, so if I activate Mount Mitchell (our highest summit) the 10 points only count once in 2022 toward Mountain Goat status. The program is designed to encourage activators to activate a wide variety of unique summits each year. It’s a brilliant motivator.
I will be happy if I achieve Mountain Goat status in 5 years. I simply don’t have the free time to hit summits as often as I’d like. It is a really cool goal though.
I do hope I can fit in a little FYBO time this weekend! If you’ve never participated in a QRP contest, this is a good one; certainly one of my favorites. The rules are incredibly simple and you can even simply do a park or summit activation during the contest then send in the logs to FYBO as well without using any special exchanges (with that said, be ready to reply with an exchange including the temperature on site!).
Here are the rules for FYBO (Freeze Your B___ Off) Contest:
FYBO Winter QRP Sprint, sponsored by the Arizona ScQRPions
First Saturday in February from 1400Z-2400Z
QRP HF Only. CW or SSB (5W max). Near QRP calling frequencies (no WARC bands).
ENTRY SUBMITTAL AND SCORING IS NOW FULLY AUTOMATED!!! No waiting! No suspense! Submittals can be edited if you made an error. All the entry items and calculations are shown below, but you don’t do anything but count up the Contacts, SPCs (States/Provinces/Countries), number of contacts with NQ7RP and choose your multipliers based on the definitions in the sections below.
Many many thanks to Diz (W8DIZ) at QRPContest.com and Kits and Parts for including us on his QRP Contest site! This is a first class bit of work by Diz and is much appreciated!

Single Op (Home/Field) One Operator/One Station/One Call
New starting in 2016 is the “Work Anyone” contact. Any contact you make now is a FYBO contact. There are now many more overlapping field activities especially with the advent of SOTA, POTA, Grid Squares, VEs, SITW (Squirrels In the Woods), and NPOTA (National Parks On The Air). Work everyone you can. More fun anyway. Activators and Chasers from other events are very welcome.
New in 2015 was the TEAM category. That has been discontinued starting in 2018, but you may note a team on the automated entry and scoring form.
If you operate from separate batteries dedicated to the operation of the radio while in a vehicle it qualifies for the Alternative Power bonus. The vehicle battery charging system qualifies as a petroleum driven generator. You may charge batteries from the vehicle if you wish but they cannot be charged via the vehicle while the station is on the air.
Work stations once PER band. Score 1 point per QSO.
Exchange RST, State/Province/DXCC Country (SPCs), first name, power out, and Temperature (Fahrenheit) at OPERATOR’S POSITION. Indoor stations must report INDOOR temperature.
Example: 579 AZ Frosty 2W 40F
IF you are participating primarily in a non-FYBO activity, send your normal exchange for that activity. Including Signal Report, SPC (State or Province or Country) and Temperature would be nice for us, but optional.
Multipliers:
SPCs (each counts once PER band),
Field Location: x4 (Field per ARRL FD definition),
Alternative Power: x2 (per ARRL FD definition),
QRPp (less than 1W): x2,
Lowest Operating Temp (at OP’S POSITION):
65+ F = x1;
50-64 F = x2;
40-49 F = x3;
30-39 F = x4;
20-29 F = x5;
Below 20 F = x6.
For contacts with NQ7RP, add 100 points. One contact PER mode PER band allowed. There may be multiple NQ7RP operations such as NQ7RP/5. Either one but not both, counts. See example below.

QSOs – Report the number of non-duplicated QSOs on bands that you have made contacts. SPC – Report the number of non-duplicated States/Provinces/Countries on those band. NQ7RP – Report the total number of contacts made with NQ7RP on all bands. A maximum of ONE contact with NQ7RP is allowed per band.
Stations may be contacted again on different bands, but only once within a band.
Modes are defined as CW, SSB, and Digital, but will not be differentiated in the scoring.
Final Score = 82 QSO Pts X 44 SPC = 3608 X 5 (Temp Multi for 28F lowest temp) = 18,040 X 4 (Field Ops) = 72,160 X2 (Alt pwr -Solar) = 144,320 + 100 X 3 NQ7RP bonus points = 144,620 Total points
If you work NQ7RP(/x) on a band, please enter a “1” in the NQ7RP column for that band/segment.
Alternative power is a non-generator or mains power source. Batteries count if they are charged from solar, wind, or some natural source of energy. Here is an excerpt from the ARRL Field Day rule…
7.3.8. Alternative Power: … without using power from commercial mains or petroleum driven generator. This means an “alternate” energy source of power, such as solar, wind, methane or water. This includes batteries charged by natural means (not dry cells). …
Please include your soapbox comments with your summary! We’d like to hear of the trials of cold-weather operating, and any and all anecdotes are appreciated. You can put a link to your pictures in the soapbox area.
Logs are due 30 days after contest.
Please put your comments in the Soapbox area along with a link to any pictures.
NOTE: This is a fun contest, NOT an episode of Survivor. Be aware of the temperature and the possibility of cold injury! PLEASE be careful.
I mentioned on Twitter yesterday that I recently took delivery of the Venus SW-3B three-band QRP transceiver.
Yes, I finally made the purchase after being encouraged to do so by so many of you. (I’m often accused of being an enabler, but I promise it works both ways!)
It’s very early days with the SW-3B, but I’ll admit that I like this little radio. I’ve been chasing a number of park and summit activators yesterday and today at the QTH while writing a few reviews.
I’ve discovered a few interesting quirks, but it’s a cool little radio.
All-in-all, though, the filtering is pretty good and the receiver quite capable. The CW keyer is excellent.
I’m looking forward to taking this little rig to the field soon!
Many thanks to Bill (W4FSV) of Breadboard Radio who shares the following announcement:
40 METER “Woodpecker” QRPp Transceiver Kit From Breadboard Radio
Breadboard Radio has just released the 40 Woodpecker, a 40 meter low power CW transceiver for the 40 meter band. The Woodpecker features a crystal controlled transmitter with a 500 milliwatt output. The transmitter provides sidetone, receiver muting and QSK with delay. The Woodpecker’s direct conversion receiver has an adjustable bandpass filter, attenuator and an audio amplifier suitable for headphone level output plus a selectable low / high filter which helps with band noise and static crashes. The kit is supplied with crystals for 7030 and 7056 kilohertz. Other frequency crystals may be user supplied.
The designer, W4FSV has made multiple contacts using a 40 meter dipole antenna including many from 500 to 1000 miles. The kit is complete with all parts including a cabinet and attractive front panel plastic decal. A two channel 30 meter version may be available soon. A 60 meter version is also available.
Many thanks to Ron (KK1L) who asks the following question after reading my post from January 2021 regarding the decision to keep my Elecraft KXPA100 amp instead of selling it:
Hi Tom,
If after a year of opportunity to reevaluate have you changed your mind? I am looking for an opportunity to wrestle with the same dilemma.
73 es God Bless de KK1L, Ron
Thank you for your question, Ron!
It’s funny you should ask. Only a couple months ago, when I re-arranged my shack, I thought yet again about selling the KXPA100 because it gets so little use as I run QRP 99% of the time both in the field and at the QTH.
The thought occurred to me that I could sell it and easily afford a dedicated 100 watt radio for the shack–either a brand new Yeasu FT-891, or an Icom IC-7300. With a little extra money added, I could even purchase the new Yaesu FT-DX10. That was very tempting.
Possibly most tempting would be to get a used Elecraft K3 or possibly a K3S; more of these have been appearing on the used market after the introduction of the K4.
Also, I had an opportunity to purchase a used mint Icom IC-7200 with a full side rail kit; I’ve always loved both the receiver and look of this particular radio! It, too, was tempting.
With this magic FT-8 box and a little power bank, all you need to make FT8 in SOTA expeditions is your smartphone.
I don’t own this product, but found it might interest many people visiting your excellent website.

Lab599 Discovery TX-500 Covers
Many thanks to Mike (KG4MTN) who writes:
Hi Thomas,
I have just received a nice set of 3D screen/keyboard covers from KB7MDB for my TX-500. Along with these covers he included 5 screw-on plug covers. All appear to be nicely made and fit my rig just fine. Cost was $15, which includes shipping. I have the 2-cover set, I believe he also makes a single-cover unit. Mine is black but I think he also makes them in orange. Shipping is very prompt. His Etsy site is Brewer 3D Design LLC.
The Maxpedition EDC Organizer holding my MTR-3B and accessories in this photo.
Many thanks to Ray (K8DRT) who reminds us of an ongoing sale at Maxpedition’s main website. The sale includes a number of popular Organizer Pouches including the Fatty which I use for my Elecraft AX1 antenna, and their smaller EDC organizer that I’ve used for a number of radio accessories, logging pads, and EDC items over the years.
Recently on Twitter, I created an informal poll and asked if anyone else named their radios.
Here are the results:
I quickly found out that I’m in the 6.7% minority who freely admit that they name their radios.
We can also assume, however, that a healthy percentage of the “Neither confirm nor deny” crowd do too. They just have a professional reputation to maintain!
Truth is, I don’t name all of my radios; only the ones with “personality” that I plan to keep permanently.

My gift to myself after completing my very first CW activation in 2020 was to purchase a Mountain Topper MTR-3B from LnR Precision. I’ve always admired these tiny hiker-friendly transceivers and have watched as Steve Weber (KD1JV) updated the design over the years.
I’ve had a lot of fun testing the Xiegu X6100 in the field. Each time I’ve taken this little shack-in-a-box radio outdoors, I’ve paired it with a different antenna.
On January 10, 2022, I decided to try one more antenna: the PackTenna 9:1 UNUN random wire.
The Packtenna random wire is a brilliant little antenna to pair with radios like the X6100 that have built-in, wide-range ATUs. It’s such a small antenna and can easily find matches on my favorite POTA/SOTA bands: 40 meters and up. It’s also very compact and super durable.
There’s no cure for my pack obsession. I’m constantly in a state of assembling and testing the most efficient kits I can conjure up.
Since I rotate a fair amount of radios in my activations, the majority of my kits are modular; meaning, components like antennas, ATU’s, batteries, log/pen, and cables are packed in their own small pouches/pack. Before embarking on an activation, I simply assemble the components in a backpack along with the radio/s I might use that day. Over the years, I’ve developed a certain workflow with this process that ensures I don’t forget components or pack the wrong ones.
But by far, my favorite type of kit are those that are fully self-contained–proper grab-and-go kits that have everything I need inside to, for example, activate a summit.
