I made a short post yesterday morning noting that I planned to take my Venus SW-3B and new field kit out on a maiden SOTA/POTA activation.
While I will be publishing a full activation report and video, it could be a good two weeks down the road.
I’ve gotten so many inquiries about the SW-3B, I thought I’d write up a short recap with some of my initial notes using the SW-3B in the field.
This isn’t a comprehensive review; just some beginning field notes I made for a full review I’ll write for The Spectrum Monitor magazine.

This was also a shake-out for my Tom Bihn HTL2 field kit which will likely be shared with the SW-3B and Elecraft KX1. It includes everything I need to deploy the SW-3B in the field–including an arborist throw line!
I confirmed that everything in the kit worked and there were no missing components.
I paired the SW-3B with my PackTenna Mini 20 meter EFHW. This limited me to the 20 meter band, but I suspected it would yield enough contacts to validate my summit (4) and park activation (10).
I fed the Venus SW-3B with a 3 Ah 12V Bioenno LiFePo4 battery pack–my output power would’ve been about 5 watts.
In short? It really couldn’t have gone better.
I worked a total of 43 stations in 44 minutes on the air. Here’s what my contacts look like on a QSO Map (click image to enlarge):
Venus SW-3B Field Notes
Overall, the experience of using the SW-3B was brilliant.
Since this little rig doesn’t have an internal speaker, I recorded the audio with an in-line Sony digital recorder. Later, when I produce the activation video, hopefully I can blend the separate audio channel with the video successfully. (Any YouTuber worth their salt can do this, but keep in mind I’m not really a YouTuber!)
- Excellent receiver for field activations. I noticed no overloading and it handled the pileups very well.
- Very pleased with CW filtering.
- I was able to successfully program the “CQ” button with the following message: “BK TU 72 DE K4SWL” This is huge. At one point, the SW-3B could only handle a simple CW + callsign message. I’m very pleased its only message memory slot can hold the end of my exchange. Also, it is very easy to program.
- The SW-3B is incredibly compact; only slightly bulkier than the MTR-3B if you include the encoder and AF/RF gain pot protrusions.
- I am loving the dedicated AF and RF gain pots.
- Display is very easy to read in the field.
- Changing the CW keying sped on the fly is really not an option. It’s an awkward process.
- The sidetone isn’t adjustable without modifying an internal component. If I could, I’d lower it just a notch or two. As-is, it’s perfectly fine, but adjustable sidetone would be a nice feature.
- When switching bands, the SW-3B defaults to saved memory allocations (not the last used frequency). If you forget and switch bands, then turn the encoder, it cycles through saves memory allocations instead of up/down tuning.
Keep in mind: this is my first activation with the SW-3B. I don’t typically form strong opinions until I’ve taken a radio on at least three or four activations and used it at the QTH extensively. With that said, first impressions are great. This radio offers much more than I would ever expect for $188.
I see why it has has become so incredibly popular among CW field activators. Now that the Mountain Topper MTR-3B is no longer available, this is a viable alternative.
I’m sure some of you may be trying to decide between the MTR-4B and the SW-3B. I will be reviewing an MTR-4B soon, but based on my experience with the MTR-3B, I don’t think you could go wrong with either radio, frankly.
The MTR-4B does allow for a total of 3 CW message memories that are very easy to access and include beacon mode. You can also adjust the sidetone volume on the MTR-4B (requires opening the enclosure to make the adjustment). Obviously, the MTR-4B is a four band radio including 80 meters in addition to 40, 30, and 20.
The SW-3B, however, has an AF and RF gain control–the MTR series has no volume control at all. The SW-3B also has a rotary encoder which makes chasing contacts across the band much easier.
The MTR-4B receiver current is roughly 27 milliamps. The Venus SW-3B closer to 40 milliamps. (Yeah, splitting hairs here!)
In the coming weeks, I will be posting a number of activation reports and videos using the SW-3B. As I mentioned, I’ll also post a comprehensive review for The Spectrum Monitor magazine in the coming months.
I can say this: if you’re a CW op who is searching for a compact field radio? The SW-3B is a no-brainer. Just grab one.
If you still can’t decide between the MTR-4B and the SW-3B, consider getting both. Why? You could easily kit out two independent fully self-contained field packs on the (relative) cheap!
This will give you two choices for grab-and-go field activations.
As always, I’d like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I truly appreciate the support.
Your support not only pays the bills at QRPer.com, but makes it possible for me to purchase radios like the SW-3B.
I hope you get an opportunity to play radio this week. Stay healthy and safe out there!
Cheers & 72/73!
