I came across the Byonics website today.
While I cannot understand why anyone would want to advertise the location of their car via a continuous beacon on a 2m fm radio, especially when the car is unattended in a car park, the devices offered by Byonics look interesting and may have other uses for the enterprising electronics or amateur radio experimenter.
The APO3 automatic power-off device is one example. If your battery voltage drops below a predetermined level, it turns off the power to the radio.
As planned I operated in this relaxed event tonight, for a couple of hours.
I decided to use my IC703, partly because it has a CW filter and I know how useful that is even in a quiet cw contest. (I should get one for my FT817). The other advantage the IC703 has over the FT817 is that it has a speech compressor which improves the average power output on SSB. But as a test and a self imposed handicap I decided to cut the IC703 power level down from its nominal 10 watts to 2 watts for this event.
First an hour on CW, where I made 11 contacts. As you can tell this is not a hard paced, highly pressured event.
Then an hour on SSB where I made 17 contacts, a few more than I did last year. I recognised some of the callsigns from last year and also made contacts with friends such as Mike VK2IG, Murray VK1MDP, Waldis VK1WJ and Peter Vk3YE.
I don’t think running 2 watts instead of 5 or 10 made any difference to the number of contacts made. While 10 watts is 5 times higher, which translates to 7 decibels, 80m generally provides good propagation and there is more than enough “head room” in the available signal levels for QRP signals to be easily readable. 80m can be a noisy band on SSB especially late at night. There was some electrical storm noise but it wasn’t too bad. Another time those 7db might have been quite important.
A few interstate stations gave me good signal strength reports so the old 80m dipole at 6 metres above ground was doing its usual job.
The low dipole isn’t any use for dx though. I have heard some US and JA signals on the CW end of the band but even the strong ones rarely even return a QRZ? to my call. Have to get a decent vertical going on that band to work dx.
Reminder that the QRP Hours contest is on 14 April 2012. Rules are in AR for April 2012.
Here is a link to the rules on the QRP club site.
1000 UTC to 1059: CW section 3500-3530 khz
1100 to 1200 UTC: SSB 3550-3590
QRP stations can work any station whether QRP or not.
Exchange is signal report plus serial number starting at 001. No repeat contacts.
QRP = output power no more than 10 watts.
Participation of higher power stations is appreciated as it warms up a contest to have more in it giving contacts.
