Add an On The Air LED to Kenwood MC-60 Desk Mic
In this video I show a few things to test before adding an “On The Air” LED indicator to a Kenwood TS-50 ham radio transmitter. I tested for the best brightness of the LED and lowest current using a ganged restore test box I built. The LED was then mounted in my Kenwood MC-60 desktop microphone.

HF Ham Radio Kenwood TS-50S Panel Button Repair
The buttons in my Kenwood TS-50S ham radio started falling out when the foam inside started getting old. The foam was the only thing holding the buttons in so I used jewelry repair rings from Michaels Store to clamp around the base of the buttons inside the bezel face plate which then holds the buttons in nicely yet lets them have full travel and good tactical feel.
ISO-TIP 7700 Soldering Iron Review
I recently had the opportunity to try out a new ISO-TIP 7700 soldering iron. This is a rechargeable soldering iron without a lot of extra features but it is plenty capable for small soldering tasks. Here’s a few specs from the ISO-TIP web site:
– Fully recharges in 3.5 to 4.0 hours
– Partially charged battery to full capacity in one to two hours
– Up to 125 soldering joints per charge during continuous use
– Withstands high-rate charging without damage
Here’s a short video of the circuit blinking away, proving that I can solder together a simple circuit: Video of circuit blinking Yes, the circuit did work the first time.

GQRP / Kanga receiver
I was sent a kit this week by Kanga UK, who supplied me a new regen receiver. The kit in question makes its debut at the GQRP convention at Rishworth UK this week. Its appearance is marked by the annual buildathon.
The buildathon is a great way for anyone who has an interest in electronics, radio or has indeed has no experience in construction, build a kit and walk away with a working radio. The step by step guide we supply with the kits allows easy installation of the components and instant gratification.
I wrote the instructions for this kit and whilst doing so, I managed to video the whole build. The video is sped up, but the build actually took about 2 hours, not rushing and includes the videoing & taking pictures.

Surface mount soldering
If, like me, you have had an irrational fear of surface mount devices for some time, you will be glad to know its not as bad as you may think. I recently started working with SMD and while I suffer from shaky hands and have poor eyesight, its actually quite a methodical process and not as fiddly as you would think.
I created a 2 part video on SMD soldering using a hot air (reflow) station and using solder paste. In this video I created a QRP dummy load which is a great introduction into Surface Mount Components and at a great price of £5.95 available from Kanga Products
