Venus SW-3B Review from a newbie SOTA/POTA activator’s viewpoint
by Erik (KE8OKM)
My journey into amateur radio is relatively short (approaching 2 years now) in this short time I have become enamored with “in the field” QRP operating. Particularly SOTA/POTA.
When I started studying for my tech license I kept coming across CW–what the heck is that? After I learned it’s a mode using Morse Code (a highly effective one at that) I thought, “not interested” and “they still do that?”
Much to my chagrin, I find myself loving CW and obsessed with all things Morse! The CW mode is both a skill and an art. I am still drawing with crayons but hope to paint someday…at least like Bob Ross…
The Venus SW-3B is a small 3 band transceiver operating on the highly effective 20/30/40m bands: the SOTA/POTA activator’s bread and butter bands. To date I have logged over 450 QSOs with this little “black box.” I often come across some disparaging remarks since the transceiver is built in China.
Well before the new Xiegu X6100 transceiver was actually in production, I was already getting questions from readers and YouTube channel subscribers if they should plan to purchase the X6100 or the Icom IC-705.
The X6100 has been in the hands of early adopters now for about two months, so we have a good idea what the radio is capable of and how well it performs–at least, with the current firmware revision (January 18, 2022).
I’d planned to make a comparison video in a couple of weeks when the X6100 I purchased arrives, but as I was packing my loaner X6100 to ship to the next review last week, I got yet another email and made the decision to unpack the rig again and film a video comparison.
Several subscribers asked if I tried using the attenuator and RF gain to mitigate the level of overloading. Attenuators and RF gain can be an effective means of mitigating noise levels, but they essentially affect everything on the band–all signals somewhat equally.
A better approach is to use a BCI Filter.
BCI filters reduce or notch out AM broadcast band signals so that they don’t overload your receiver.
BCI Filters are placed between the radio and the antenna. They can have a dramatically positive effect if you live near a broadcast station and/or if you have a radio that’s prone to overloading.
I see them as a more “surgical” approach to solving broadcast band interference.
On Thursday, January 6, 2022, I woke up with one goal in mind: take the Xiegu X6100 out on a proper hike-in activation!
While I’d had this radio on loan from Radioddity since December 23rd, I hadn’t had an opportunity to truly hike it into an activation site. Between the weather and my tight schedule, I haven’t had an opportunity to plot out a proper Summits On The Air (SOTA) Activation. SOTA activations that involve hiking usually take a much bigger bite out of my day and, lately, I’ve been to busy to plot one.
I do live near a vast trail network, however, and it so happens that much of the trails run through overlapping public lands: Pisgah National Forest and Pisgah State Game Land.
So I packed my Spec-Ops EDC tactical pack, grabbed Hazel’s harness, and headed out the door.
For context, I got my ticket in 2020 and got on the air at the end of July 2020. Since that time I have only worked QRP CW using a QCX (the original) on 20 meters and then after September 2021, I got a Venus SW-3B so I have done a bit of work on 40m and 30m now as well.
I really enjoy the challenge of QRP and in a bit over a year, I worked all states, as well as Japan, Canada, several Europe countries, etc, so with good band conditions, QRP really does work and is a lot of fun. My experience working /P stated when I got the SW-3B but I only got out 3 times as the weather up in the hills west of Denver got too chilly very fast; this spring I’ll get back to more /P.

I’ve always believed that the first day of the year should be symbolic of the whole year.
At least, that’s the excuse I was using to fit in a quick activation on New Year’s Day (Jan 1, 2022).
I have had the new Xiegu X6100 on loan and planned to take it to the field, but that afternoon waves of rain were moving into the area in advance of a weather front. Since I don’t own this X6100, I didn’t want to risk getting it wet.
In fact, I had almost talked myself out of going on an activation, but my wife encouraged me to head to the Blue Ridge Parkway, so we jumped into the car and hit the road.
Our options on the parkway were very limited as they often are in the winter. In advance of winter weather, the National Park Service closes off large sections of the BRP because they have no equipment to remove snow/ice. Plus, you’d never want to drive the BRP in slippery conditions. There are too many beautiful overlooks to slide off of.
Thankfully, the Folk Art Center access is always open and incredibly convenient.

We arrived at the parking lot and I very quickly made my way to a picnic table while my wife and daughters took a walk.
