HF Radio heard from the Pacific Northwestern US. This site contains links to ham radio related projects I am affiliated with and a link to my sdr receiver. Feel free to contact me with any questions or comments. 73, Todd
While there are much fewer Shortwave stations broadcasting these days, there is still a lot of activity in the HF spectrum. The Kiwi and other wide-band SDRs really shine here as you can take a view of the entire range of HF frequencies from 0 - 30MHz and SEE what is going on in real time, scroll in on the groups of signals, click and check them out. Using tools like Shortwave-Info (link below), you can identify what you are hearing, look for programming in your native language, and get an instant list of what's broadcasting right now.
A lot of the current content is religion and politics. But you will still get Radio New Zealand, BBC, Voice of America, Voice of Korea (DPRK), and other news sources that are great for a different point of view.
If the shortwave broadcast content isn't your cup-of-tea, use Priyom.com (link below) to find utility stations and Clandestine stations including the always mysterious "numbers" stations.
Amateur Radio operators (HAMs), myself included, communicate via HF radio and can be heard throughout our band segments of the spectrum.
There are also many shortwave pirate stations that pop up between 6800 & 7000KHz that are fun to catch and listen to in the evenings. Music, weirdness, and mayhem. Many of these are discussed on the HF Underground forums. Worth checking out and logging these when you find them.

The site overlooks Lake Merwin from 1260' in Southwest Washington State. Site has a view of the Mt. St. Helen's volcano across the valley that erupted May 18th 1980.
The receiver is a KiwiSDR2 with a W6LVP Active Loop antenna for receive. It has back-up power.
Internet to the site is fed by a commercially licensed 5-gHz radio link to internet across the lake. The licensed frequency keeps me away from the public-open frequencies as to maintain good bandwidth. The internet is delivered by RF from a site on the west hills of Portland, Oregon.
The path is Portland, Oregon to Woodland, Washington, then to Davis Peak where I am gaining access. That is approximately a 50 mile RF haul but works extremely well using quality Ubiquity antennas and routers. Download speed averages about 50 mbps and upload (output) is right around 20 mbps.
Future upgrades will include a user controllable antenna switch that will allow remote switching between the loop, a beverage antenna, and hopefully other experimental antennas.
This SDR samples ALL of the HF spectrum from 0 - 30 MHz at once, allows four connections at a time, decodes DRM, Fax, NAVTEX, FT4/8, WSPR, and many more modes. There are no set time limits.
Please feel free to play around with it and have fun. I'd appreciate to hear if you find it useful.
To get a listing of ALL Kiwi's available including a map and search field: http://kiwisdr.com/public/
Start by entering or selecting something in the search criteria. When the map shoes up, drag the green-dot to SW Washington State on the map and use the search features to find stations that are broadcasting using your search criteria. You will see a signal-strength meter on the right of the stations that you should be able to hear. Same for your own region. If you have a shortwave receiver, drag the dot over your region to see what you should be able to hear at your location.
This is THE list in both text and .CSV format that can be downloaded so you can search on the fly. Many SDR programs will incorporate the .CSV file to provide a lookup withing the program. Kiwi uses this list for header tags but I've noticed that they are a bit behind. Not sure if I can update this myself in Kiwi just yet... Working on that. This schedule changes a couple of times a year for Winter/Summer broadcast schedules. Worth saving the text file to your desktop and searching it in regular old MS Wordpad or similar.
Ham Radio Operators receive call letters from the FCC just like other radio services. Try to capture them and look them up. Ham Radio callsigns will be one to two letters, a number, and one to three additional letters. Example: KB7RQQ. QRZ.com is a great source for Ham Radio information and propagation and solar weather info.
TIP: Most HAM radio transmissions below 20 Meters (14Mhz) will be in Lower Side Band or LSB. Communications above will be in Upper Side Band or USB. You will still see some hams operating in Amplitude Modulation or AM in portions of the 40m and 80m band. If you get something that sounds weird, try playing with the different modes.
Visit Priyom.org to listen in, join the search, and help contribute to researching these mysterious signals. This site will show when the next transmission is and provide a link directly to an SDR that is close. It will also put you on the right mode and frequency so you don't need to adjust anything. Priyom also catalogs what is known about each station and can provide location, what it may be, scheduled frequencies and times of transmissions for each.

Ham Radio Venture Overland, co-founded by Mike AA1PR in Vermont, is a talk group of like minded hams that enjoy the outdoors,vehicle based off-road travel, and camping. Join us!
We welcome long winded ragchews. We are very much pro-round table... so throw your call out. You are never 'interrupting' us. We welcome the conversation.

Sunday Evenings @ 6:00PM Pacific

I take part in a communications event where we coordinate and operate a radio network in support of a 200 mile endurance trail run. The terrain is 700 square miles of the Mt. St. Helens and Mt Adams wilderness of the Cascade Range in Southwestern Washington State.
We utilize, VHF/UHF FM simplex and repeaters, HF/VHF Winlink, satellite tracking of each individual runner, provide mesh networking, and Starlink internet to the many aid stations along the event route.
We provide communications for coordination with base, re-supply, search & rescue, general safety of all event goers, and can provide information about individual runners to family and crew throughout the event.
Below are some links that will give you an idea of the scale of this event. I can't imagine a better example of putting amateur radio to use in less than ideal conditions for a full week, then 'acid' testing these methods and gear. This organization, runners and crew depends on us for 100% of the communications since there is no cell access, and no line-of-sight for personal simplex radios.
If this sounds like fun? We are looking for you!
This is a video of the prep, the setup, the fun, and work of preparing and working this event. Also a demonstration of the digital communications used in the event.
Marble Mountain WA7BF - 147.16+ 103.5 (NA7Q/K7TME) Allstar #542107

NODE# 542107 (Marble) & 542108 (Merwin) both have the same feature packed controllers.

Ever wonder how/where the internet gets from one continent to another?
Hearing chirps and seeing a signal line ascend through the spectrum? Probably an Ionosonde
