IMPRO
improving-a-7-mhz-am-transceiver
This is a single frequency transmitter/tuneable receiver for 7 MHz AM. I added an extra crystal for an extra transmit frequency and made the receiver tuning range less to permit easier tuning in of stations on receive.
Contents:
0:00 Introduction
0:13 Switch for second crystal
2:59 Narrowing receiver tuning range for easier tuning
19:13 On air
19:52 Books

NO AN
no-annual-fees-for-aussie-ham-radio-a
Big changes are afoot and now is the time to have your say. Australia's ACMA could scrap amateur licence application and renewal fees and reduce regulations if we move to class licensing. Or they could keep something like the current arrangements under apparatus licensing. Which do you prefer?
Read their discussion paper, a proposed class licence and have your say here:

ARDUI
arduino-for-amateur-radio-automatic-cq
When the bands are dead does that mean there's no propagation?
Or is everyone just listening?
This video shows what happens when you hook an automatic CQ caller up to a 40 metre QRP transceiver and the sorts of contacts likely.
The caller is based on an Arduino microcontroller board (the KitTen from Freetronics) and two extra parts. The software is easily modified from the 'blink' program used to teach beginners. While it's set up for CW use, the addition of a digital voice recorder and a minor software change allows it to be used for voice modes as well.
UPDATE: Reed relay started to get a bit sticky after several days heavy use. So instead of replacing it I used a 4N25 optocoupler and 470 ohm resistor. I also moved the switch from in between the sockets to the power supply as this lowers consumption when not in use. See http://youtu.be/Gxa5l3gD8bc for the circuit.

PIXIE

In a previous video I converted a 7 MHz Pixie CW transceiver kit to a 7 MHz AM transmitter using only a minimum of added parts.
This time I go a step further, putting the Pixie on 1.8 MHz. This video describes how I do it and tests it with a range test with a portable receiver.
