Part of the series: HAM radio, QSK

"I can hear you between my signals." --Definition of QSK This netcast is a personal project. From time to time in my life I've encountered things that I want to share with others. Sharing will be the name of the game here. The topics are sure to be varied, from computers and technology to politics and sociology, from pet peeves to in-depth software how-tos. I'm not sure there's any way to put a classification on what you might hear when you listen, but the hope is that no matter what the subject it will always lead to outrage, thoughtful contemplation, sounds of disgust, a nod of agreement, a fist-shake of righteous indignation. If I can spark some neural activity or inspire a conversation, I have done my job properly. I've already described the netcast to several people who have asked as "80% tech and 20% rant." That might be a good way to sum it up; or it may not. I'm jumping in the car and going along for the ride just like you are. Along the way I hope I put out some interesting information, get tons of feedback from listeners, and overall simply engage the human race (at least the part of it that is listening to me) in a broad dialog. So dip your toes in. The water's fine. You can find the OGG Feed link at the top of the page for downloading the audio episodes to your favorite podcatcher. Let's see where the mood takes us. Intro and Outro music is "Sly Bone" by Larry Seyer.

Sub Display

Used either to display the time or in graph mode gives a representation of the receiver bandwidth setting when using CW or SSB.

Memories and band keys

Ten memory and band keys to switch either between ten stored memories or to switch between the ten pre-set amateur HF bands when in VFO mode. Up / Down step keys jumps in 1Mhz step.

Antenna Tuner

I tried and failed to find a simple explanation of an antenna tuner it’s a complicated topic, I can at least have a go at explaining how to use a simple manual antenna tuner, hope this makes some sense.

A typical manual Antenna Tuner has two rotatable knobs both interact with each other. The Tuner is used to match a badly tuned antenna to your transmitter. The Tuner is placed in-between the transmitter and antenna. To use it you typically hold down the transmit key while looking at the VSWR meter and rotating one knob at a time in turn repeating this operation until the minimum VSWR is achieved.

Great Episodes!

Thank you for doing this, I love these episodes. They keep me smiling and occasionally screaming at the podcast player. You can be such a sadist, you know? :-) When describing the tuner: "It's quite interesting to hear" - "I'm not gona do that..." Please let us hear! Sure you could find a way, like letting it tune up a dummy load or something.
On the same token, please use the radio in front of you to create audible examples. How does a signal sound, that is suffering from spark distortions and how is it improved by engaging the noise blanker?

Please don't get me wrong - the one who puts out shows is right. Your show, your choice. Please keep them coming the way you like to do them.

One more comment to the content: Hearing relays clicking is not necessarily attributed to the age of the transceiver. Even in modern gear the filter in the high power transmit path are switched by relays. I have seen "Relay switched band filter." for receive as a selling point to indicate that there is no negative impact from the switching diodes. These can affect RF performance under certain conditions.

Regards,
Michael
