VE6CN's fine line-up of Heathkit products |
I hope VE6CN wont mind me linking to his picture showing his fine line-up of Heathkit products. For a lot more pictures of Heathkit amateur radio products see http://www.ultrawebb.com/OHP/gallery.htm .
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

Dear VLF group,
Today the S/N of SAQ was much weaker here in Heidelberg/JN49IK, probably due to the high QRN levels.
I extracted a wav file containing the full message and tests. Can be used for reprocessing if of interest for someone: https://dl.dropbox.com/u/19882028/VLF/SAQ/SAQ_ afternoon01Jul2012.WAV (117 MB)
And here is a mp3 file for listening in a normal player (first 2/3 is a test procedure, then the mesage comes): https://dl.dropbox.com/u/19882028/VLF/SAQ/SAQ_ afternoon01Jul2012.mp3 (24 MB)

All,
This is to announce a new standalone QRSS/WSPR kit by Steve G0XAR and Hans G0UPL. The kit supports WSPR, QRSS, DFCW, FSK/CW, CW, Hell (full speed and half-speed), Slow Hell, and customisable FSK patterns. The WSPR encoding is on-chip. It supports the connection of a GPS module for frequency locking, accurate time, and location (for WSPR). Power output is measured at 185mW on the 30m version. We are selling versions for 30/40/80m and perhaps later 20m and 160m. It does not require a PC, it has an LCD and two buttons to control it.
The price is GBP 15.39 (EUR 19 or US $24 approximately) plus shipping.
You can see all the details here: http://www.hanssummers.com/qrsskitmm and order online at http://www.hanssummers.com/shop . We expect to be shipping by 27-29 June.
The kit supports the following modes:
+ QRSS mode (plain on/off keyed slow CW)
+ FSK/CW mode (frequency shift keyed slow CW)
+ DFCW mode (dual frequency CW, dit's and dah's on different frequencies)
+ WSPR mode (Weak Signal Propagation Reporter)
+ Slow-Hellschreiber (frequency shifted slow Hellschreiber)
+ Hellshreiber (full-speed standard Hellschreiber, and half-speed Hellshreiber)
+ CW (plain CW)
+ Customisable FSK patterns
Other features:
+ 24-character LCD + two-button user interface
+ User-programmable (callsign, message, speed, FSK, mode, etc.), settings stored in EEPROM
+ GPS interface, for locking the frequency in slow-speed modes
+ On-chip generation of WSPR encoded message (no PC required)
+ WSPR maidenhead locator can be generated from GPS-derived latitude/longitude
+ Selectable “frame” size, for stacked QRSS reception
+ Plain CW callsign identifier at selectable interval
+ Produces 150mW RF output, or AF output for driving an SSB transceiver
+ Higher output power by additional PA transistor and/or higher PA supply voltage

Transmissions on Alexanderson Day
We plan for transmissions on Alexanderson Day Sunday 1st July. If we are allowed to use the antenna we start the machine transmitter at 8.30 UTC and a message is sent at 9.00 UTC. Second start of the transmitter at 11.30 UTC and a message is sent at 12.00 UTC. The frequency is 17.2 kHz CW.QSL-reports are kindly received:QSL reports can be given via:- E-mail to: info@alexander.n.se- or fax to: +46-340-674195- or via SM bureau- or direct by mail to: Alexander - Grimeton Veteranradios Vaenner, Radiostationen, Grimeton 72, S-432 98 Grimeton, SWEDENNote: SAQ is a member of the Swedish Amateur Association (SSA) and "QSL via bureau" is OK.
The following have been notified to me. As I always advise, check before going a long way. Saturday April 20th -Yeovil ARC 38th QRP Convent...
