Pico Dragon was developed by the Việt Nam National Satellite Center (VNSC), University of Tokyo and IHI aerospace. It has a 437.250 MHz CW beacon and 437.365 MHz 1200 bps AFSK AX.25 telemetry.
Mineo Wakita JE9PEL has received the CW signal from Việt Nam’s Pico Dragon CubeSat but nothing was heard from ArduSat-1 or ArduSat-X.
Listen to the recording of the PicoDragon CW beacon made at 16:08-16:17 UTC, 19 Nov 2013, Ele 28 S-E-EN, 437.250MHz CW
The Pico Dragon beacon has been reported as appearing about 3 kHz high of the expected frequency.
Edward BX1AD reports hearing ArduSat-1: I heard ArduSat-1 CW (FM-modulated 800Hz tone) on 437.000 MHz during the pass 01:51 – 02:00 UT Nov. 20, decoded as following:

The ArduSat team have released the following information:
If you’re a radio amateur and would like to help out the ArduSat team, you can listen for our Morse beacons and send them to us! This beacon gives us important information – like battery voltage and lets us know that the satellites are still alive!
The initial TLE for AS-1 and AS-X will be the same as the ISS until they put some distance between each other and are assigned their own Noad IDs.
TLE for ISS: http://www.celestrak.com/NORAD/elements/stations.txt (What is a TLE?)
Both satellites will have a Morse beacon (FM-modulated 800Hz tones) that is transmitted at 20 WPM every two or three minutes on 437.000 MHz. The beacon will be structured in the following format:
ArduSat-1 beacon: Battery voltage (uint16_t), RX_counter (number of received valid data packets, uint32_t), TX_counter (number of sent valid data packets, uint32_t), “WG9XFC-1″
ArduSat-X beacon: Battery voltage (uint16_t), RX_counter (number of received valid data packets, uint32_t), TX_counter (number of sent valid data packets, uint32_t), “WG9XFC-X”
Submitting a beacon packet:
You can submit a beacon as plain text to email@example.com – be sure to put the word “packet” in the subject line so that we can parse it quickly.
You can submit audio as an email attachment. Send an email to firstname.lastname@example.org – with the audio file as an attachment.
