Chasing States
Sometimes, I just need a reason to get on the air. Specific operating goals can help with this, whatever form they take, including operating awards. One of the first awards I earned many years ago was Worked All States (WAS). The mixed WAS is not that difficult because you can use any of the HF bands to make the contacts. Some bands are better for close-in states while others are better for long distances. Do a lot of operating, and you’ll eventually earn WAS. And it is fun to chase states.Six Meter WAS
A few months ago, I looked at my Logbook of The World (LoTW) stats and noticed that I was one state shy of having WAS on 6 meters. I was not working towards this objective, but I was making a lot of contacts on six, trying to work countries and grids. The state I was missing was Utah, which is adjacent to my state of Colorado. I know I had worked Utah before, but I didn’t have it confirmed. Utah is not that easy to work from my location, because the populated areas of the state are in a dead zone: too far away for tropo propagation but too close for sporadic-e. Once I realized I only needed Utah, I kept watch for Utah stations showed up on 6 meters. Soon, I worked KI7MD using meteor scatter and asked him to confirm the contact in LoTW. OK, there you g, I had WAS on 6 meters. I consider this a real accomplishment, one that took many years.Chasing States By Band
Well, of course, it did not stop there. Another review of my LoTW results by state and band revealed that I already had WAS on 20 meters. I patted myself on the back for that accomplishment, even though I just stumbled across it. Then I noticed I had 43 states on 40 meters. Hmm, that should not be too difficult to complete because 40m propagation covers the US quite well. Alaska and Hawaii were both already confirmed so the challenge was filling in the missing lower 48 states. I’ve been doing quite a bit of FT8 operating lately, so I set JTAlert up to alert me when any of the states I needed were received on 40 meters. Whenever they popped up, I’d make it a point to work them, if possible. Soon, the missing states were filled in, and I had achieved WAS on 40m. Technically, I have the confirmations in LoTW (good enough for me), but I have not applied to have the award issued. Well, what band should I pursue next? I was a latecomer to the 30-meter band, making my first contact on that band in Feb 2024. However, I have learned to really like it with its propagation characteristics being an interesting mix of stateside and DX. I had about 30 states confirmed on 30m, so I figured it would not take too long to fill in the blanks. Again, I used FT8 aided by JTAlert to keep watch for the states I needed. I wasn’t completely zoned in on working these states…usually, I was on the air for other reasons, but when JTAlert told me there was a WAS contact to be had, I grabbed it. Right now, I have 49 states confirmed on 30m, with Delaware being the only one missing. Now, someone out there is thinking, “Don’t pursue WAS one band at a time; go for them all at once!” That probably would be more efficient, but that’s not what I am after. I just like having a few operating goals in front of me to focus my efforts and pursuing states on a single band fits that just fine.WAS Score Card
Here’s a snapshot of my WAS numbers today, from LoTW. After I finish up 30m, I will probably focus on 15m or 10m. I tend to be on those bands anyway for chasing DX. On those bands, I seem to be missing the closer in states with lower population density such as Kansas, North Dakota, Nebraska, New Mexico, and Utah. This is predictable with the longer F2 propagation normally found on those bands.
I don’t know that I’ll ever get WAS on 2m and I am more focused on VUCC for that band. Note that I have 4 states on 70cm: Arizona, Colorado, New Mexico and Wyoming. I am a bit surprised by that. Anyway, if you are looking for a reason to get on the air, chasing states might be interesting. Remember, it’s all about having fun messing around with radio. 73 Bob K0NR The post Chasing States appeared first on The KØNR Radio Site. Ham Radio License Class – Monument CO

VP2V/K0NR: Another Slacker DXpedition
Operating from countries outside the US can be a lot of fun. I just completed another Slacker DXpedition, this time to the British Virgin Islands. The formula for this type of operation is simple: identify an interesting vacation spot that is also considered DX, travel there with friends and family, take along some compact radio gear, and get on the air. 
A key point is not to overdo the radio operating, or the friends and family will veto any radio activity on future trips. This was not a super-gonzo turbo-charged DXpedition. I just worked in some radio action in between snorkeling and exploring the island. This is referred to as a “holiday style” DXpedition, or maybe it’s just the slacker approach.
VP2V British Virgin Islands
The idea for this trip originated with a group of friends who often travel together to fun places, often an island in the Caribbean. BVI had been on our list for a while, and we had a trip planned back in 2020, but the COVID-19 pandemic caused us to cancel it at the last minute. It has taken us some time to get a plan back together, but here we are doing the trip five years later.
When a travel opportunity like this surfaces, I check out the implications of amateur radio licensing for that country. For a US radio amateur (and probably most other countries), getting a radio license for VP2V is easy. The Telecommunications Regulatory Commission (TRC) website has clear instructions on how to apply. Joyce/K0JJW and I filled out a form, provided copies of our passports and FCC licenses, and paid a $20 license fee. This did require a trip to a notary public to have these documents notarized. My friend, Paul/KF9EY was on the trip so he also obtained his VP2V license.
Location
We rented a fantastic house (Ana Capri Estate) on the north side of the island of Tortola. This house has a great view out over the water. Tortola is the main island of the BVI, and international flights are available at the airport on the east end.
The Ham Station
We took along our usual portable ham station, with a few updates. Our Yaesu FT-991 has served us well for POTA, SOTA, and island activations in the past, so it is our go-to radio for this sort of operation. The key features include a 100-watt RF output, a built-in sound card for digital modes, an internal antenna tuner, and a small enough size. This radio has HF plus 6m, 2m, and 70cm, which can be handy. Add a compact Samlex switching power supply, and we are ready. Recently, we have moved away from using End-fed Halfwave (EFHW) antennas and started using an End-Fed-Random Wire (EFRW), also called an End-Fed Long Wire (EFLW). The difference is subtle but important. The EFRW uses a wire length that is intentionally not resonant on any band, fed by 9:1 UNUN matching device. This setup radiates well over a range of frequencies but does require an antenna tuner because it is not a consistent 50-ohm impedance on all bands. I’ve found this to be a reasonable tradeoff between quick-changing band coverage and performance.
For this trip, we used the Palomar Engineers Bullet-9 UNUN, rated for 500 watts PEP. A variety of wire lengths can be used with this approach, with longer wires supporting lower frequencies. The 34-foot wire element supports operating on all bands from 40m to 6m, supported by the SOTABeams Travel Mast. The Travel Mast compacts to just 26.5 inches and extends to 32 feet. Actually, I modified the top of the mast to make it stronger, so the net height is closer to 29 feet. The end-fed wire antenna is almost vertical when deployed in this manner.
In past portable efforts, I’ve encountered issues with inconsistent antenna match and RF getting back into the FT-991. I checked this out carefully before the trip and adopted some mitigation practices that seem to help. First, I made sure the wire antenna could be supported almost vertically. This is not a strict requirement but it seems to help with getting a good match across all bands. I don’t use a counterpoise, but I do have 50 feet of RG-8X coax lying on the ground, which provides a bit of counterpoise. This length of coax also lets me keep the antenna separated from the transceiver by a reasonable distance, reducing the opportunity for RF to get back into the transceiver. Finally, I use a short USB cable, with ferrite cores on both ends, to connect my notebook PC to the FT-911. In the past, the USB connection between my PC and radio sometimes quit. These precautions appear to have paid off, as the station worked without any issues.
Operating
We set up the station outdoors under a covered patio to enjoy the fantastic view and (mostly) great weather while operating. This was not optimal, as we did get chased inside a few times when rain squalls moved in. They never lasted long, so I think the tradeoff was worth it.
The propagation on the HF bands has been quite good lately, and we continued to enjoy that while in BVI. We did not have much of an operating plan (“slacker style”) but intended to operate on the higher HF bands, mostly 20m and higher, using SSB, FT8, and FT4. Bob/W0BV pointed out that VP2V is somewhat rare, showing up at number 114 on the ClubLog Most Wanted List. Sure enough, whenever we called CQ, we were greeted with a nice pileup.
My VP2V/K0NR log has 1030 contacts, including 61 DXCC entities and 23 CQ Zones. I focused mostly on keeping the run rate up and just making contacts. About half of the Qs were with the US. The logs of VP2V/K0JJW and VP2V/KF9EY are not included in these numbers. I tended to stay on the higher bands as they were working quite well.
VP2V/K0NR Log Band Phone Dig Total % 30 0 79 79 8 20 0 46 46 4 17 0 90 90 9 15 0 161 161 16 12 44 349 393 38 10 0 260 260 25 2 1 0 1 0 -- ---- --- --- -- Total 45 985 1,030 100
As you can see from the numbers above, I made a lot of digital contacts (FT8/FT4). I found FT8 to be slow, and the normal FT8 frequency became crowded. There was much less congestion on FT4, and the run rate was better, so I found that to be effective. I enjoyed the SSB pileups for a while but found it to be a challenge to manage them. While I can work CW, I did not try to manage a pileup on that mode.
I found a 2m repeater on the island 146.73 MHz (—offset, no tone) and made a few calls on it, but I did not receive a reply.
QSLs will be via Logbook of The World only. I won’t be printing cards for this effort but the logs for VP2V/K0NR and VP2V/K0JJW are already loaded into LoTW. Thanks to everyone that worked us!
British Virgin Islands
BVI was a fantastic place to vacation. During our ten days there, we enjoyed the beaches, snorkeling, and sailing excursions. If you are interested in that, there are many online tourism sites to explore.
Thanks for stopping by.

Operation Manna 80
A very special, special event station
SARC has been asked to participate in a large-scale special event late in April commemorating the relief efforts of the winter of 1944-45 to drop tons of food to the starving population of NW Holland. It is well described at: Operation Manna @ 80 and in the video https://youtu.be/0PwhYFdzY_Q. Amateur stations from the drop zones in Holland, air force bases in Britain, plus the Allied forces that provided aircraft and pilots, including the UK, Canada, The US, Poland and Australia will be represented by special event stations in those countries.
Three UK Teams, one at the International Bomber Command Centre, another at former RAF Binbrook (an Operation Manna Airfield in the UK) and another at the 100th Bomb Group Museum Thorpe Abbots representing the US operation Chowhound from a former Chowhound airfield.
The national Radio Scouting team (Plusscouts PA3EFR/J) will be operating from an Operation Manna drop zone near The Hague, The Netherlands. Read on for further details on this team and their radio station location at The Team in the Netherlands – Operation Manna @ 80
The stations will be active April 25-27 (Friday through Sunday) using variations of the xx80MAN callsign. Here in Canada, we will be applying for VE80MAN.
Children and youth activities will also be included and there will be activity on HF, DMR and VHF

SARC-SEPAR Winter Field Day
Winter FD was pretty good!
Five of us set up in three sites at Derby reach including Paul VE7VP and 3 newer hams (Carl, Barbara, and Elaine from the last class). John VE7TI and Summer School graduate Grace VA7LZT came out and Grace was able to work 20m for a while which was great. We only made around 60 or 70 contacts, but we were operating more casually. We had a fair number of visitors, both Ham and non-Ham.
A full report will follow in the next Communicator.
