Arm yourself with at minimum access to an [http://websdr.org/ WebSDR site] or a [https://a.co/aksM6al cheap Software Defined Radio (SDR) kit] with a modest outside wire antenna
running a SDR live distro like [https://skywavelinux.com/ Skywave]. Here are a list of challenes that involve capturing various signals.


Arming yourself with at minimum a [https://a.co/aksM6al cheap Software Defined Radio (SDR) kit], a modest outside wire antenna, and some open source software we will post a series of challenges that involve you capturing a signal and deciphering the message to unlock the next challenge. We will focus on live signals on the HF bands and look to complement with some recorded signals for those who may not have a station setup.
* Find three time stations on the HF Band from three different countries
* Besides time, what other services do some of theses time stations provide
* Find a NDB beacon serving an airport local to you. (Hint: they are between 150 to 500 KHz)
* Where is the nearest NOAA Weather station to you (Hint: stations are on VHF)
 
More challenges will be added.

==== Single Sideband (phone/voice) NETS ON HF BANDS ====
 
Henry "Strick" W6REK is announcing 20m and 40m radio nets on four days, Wednesday through Saturday (in North America).
 
Net controls and relays may be under a W2H call sign (possibly "W2H portable six")
or with their individual call sign.  We need relays, if you can help.
W6REK will be transmitting from San Jose, California.
 
Listen for us, up or down, within 20 kilocycles of the frequencies below.
Once we start, we will post the exact frequency to the _Hallway Discussions_ channel on Riot
( https://riot.hope.net/#/room/#hallway-conversations:hope.net )
since our station W2H has traditionally been located in the _Hallway_ on the 18th floor.

HOPE XI is the first year we ran an Amateur Radio repeater encouraging licensed attendees to make new contacts. We tried adding an [http://echolink.org/ Echolink node] so we could have global reach but it did not work out. This year we will look to run a one hour net.
Is anyone organizing a VHF, UHF, or internet-mediated net (like DMR or Echolink or Allstar)?

Welcome

The intent is to help people experience various wireless communications projects/services available to makers, hackers across the Radio Frequency (RF) Spectrum. Whether you have a (Amateur Radio) license or not, you can enjoy ways of sending and receiving RF signals. All activities are targeted at the beginner and intermediate level.


Activities

Exploring RF with SDR for the Absolute Beginner

Wednesday: 1800 EDT/2200 UTC (One Hour)

Friday: 1300 EDT/1700 UTC (One Hour)


A guide on the bare minimum information required for you to quickly experience capturing, listening, and processing (decoding) signals with open source and off the shelf SDR resources. Hardware of choice will be the RTL-SDR v3.


Capture the Signal for the Absolute Beginner

Wednesday through Sunday

Arm yourself with at minimum access to an WebSDR site or a cheap Software Defined Radio (SDR) kit with a modest outside wire antenna running a SDR live distro like Skywave. Here are a list of challenes that involve capturing various signals.

  • Find three time stations on the HF Band from three different countries
  • Besides time, what other services do some of theses time stations provide
  • Find a NDB beacon serving an airport local to you. (Hint: they are between 150 to 500 KHz)
  • Where is the nearest NOAA Weather station to you (Hint: stations are on VHF)

More challenges will be added.


Show and Tell

Thursday, Friday, Saturday: 1800 EDT/2200 UTC (One Hour)

Do you have an Open Source RF project you would like to share? You chance for 15 minutes of fame as we open the floor to hear four projects over the hour. Contact us to slot you some time at rfvillage AT cupano DOT com


HOPE 2020 Radio Nets

Single Sideband (phone/voice) NETS ON HF BANDS

Henry "Strick" W6REK is announcing 20m and 40m radio nets on four days, Wednesday through Saturday (in North America).

Net controls and relays may be under a W2H call sign (possibly "W2H portable six") or with their individual call sign. We need relays, if you can help. W6REK will be transmitting from San Jose, California.

Listen for us, up or down, within 20 kilocycles of the frequencies below. Once we start, we will post the exact frequency to the _Hallway Discussions_ channel on Riot ( https://riot.hope.net/#/room/#hallway-conversations:hope.net ) since our station W2H has traditionally been located in the _Hallway_ on the 18th floor.

BAND & SSB Freq ± 20kHz EDT PDT UTC
20m USB 14290 Wed 8pm Wed 5pm Thu 0000
40m LSB 7190 Wed 9pm Wed 6pm Thu 0100
20m USB 14290 Thu 8pm Thu 5pm Fri 0000
40m LSB 7190 Thu 9pm Thu 6pm Fri 0100
20m USB 14290 Fri 8pm Fri 5pm Sat 0000

20m USB 14290 Sat 8pm Sat 5pm Sun 0000
40m LSB 7190 Sat 9pm Sat 6pm Sun 0100


Other nets? TBD...

HOPE XI is the first year we ran an Amateur Radio repeater encouraging licensed attendees to make new contacts. We tried adding an Echolink node so we could have global reach but it did not work out.

Is anyone organizing a VHF, UHF, or internet-mediated net (like DMR or Echolink or Allstar)?


W2H Operating Schedule

To ensure maximum opportunity, we will have multiple stations across the US operating as W2H this week according to the schedule below.

Each cell indicates the Amateur Radio Bands and mode we will be using.

Digital modes (DIG) may be any number of modes. Voice will be LSB for 80 and 40 meters and USB for 20 through 10 Meters.

Successfully contact us or send date/time/band/mode you heard us and you will receive a electronic verification postcard (aka eQSL.) EMAIL your report to rfvillage AT cupano DOT com

Check this schedule often is it will be updated daily.

FAQ

Don't have a radio?

No problem. Check out these freely accessible online SDRs.

What can I use to decode digital modes

Recommended cross-platform software includes FLdigi and WSJT-X. Will be updating this page on how to use the software with a radio or piping from audio from an online SDR.

Can I still decode digital signals if I am using an online SDR?

Yes. Using virtual audio cable you can pipe output of online SDR to input of digital decode software.
