Several days ago I received a Kenwood TH D74 portable transceiver. Although I have a Yaesu FT60 and some other smaller and unimportant transceivers, I don’t have any transceiver that is APRS capable. What’s more important, this transceiver is BT and USB capable, providing serial communication, which opens some interesting opportunities. Today I opened XCode …

We first met — I think — in the summer of 2015 during the Hamfest in Friedrichshafen. At that time I had a mobile Kenwood transceiver TM-D710 which was quite nice by its own. However, after several months using the TM-D710 I got increasingly annoyed by some of its shortcomings, most of them purely subjective (but I …

Winter is finally here and the weather is suddenly much colder. I bought two styrofoam boxes, the types used for carrying fish, and I made two shelters for the stray cats. Hope will be warm and cosy. It just struck me that this is the 100 post I published on this blog. Nice. I have …

My new iPhone X is beautiful, a bit too expensive for what it offers but… what the heck. It’s a nice toy. Fancy one. Yet, something annoys me each time I sync my phone with the iTunes. I do this mostly for syncing music from my library. Each time I press the sync button, a …

Over the past seven years (the age of this blog) I started writing several articles that I never  finished. It’s time to trash them completely or just add them to a list for future afterthoughts. Who knows ? So, from older to newer: „Weller WD 1000 M Review – Part III – Software”, January 18, 2013 — …

This is a beacon project started by my friend YO5VAE. He faced some issues while programming of the Si4463-based module and I thought I might give a hand. I resoldered the entire project on an empty Arduino shield to allow expansion of the project with some additional modules. Below are some pics, but probably the …

I twenty dollars for this superb cassette deck. The playback and recording heads were in excellent shape and I used this deck for some years, playing and recording on NOS (new old stock) tapes, mostly chrome type II and metal – type IV, that I purchased on eBay. However, one day the entire head block …

There is nothing better than marrying several hobbies and have fun from it. I have had the intention to be part of this expedition at least since I heard about this contest for the first time. My good friends from Năsăud planned this thoroughly. All our equipment was carried by three 4×4, manned by a …

This old reel-to-reel was the joy of my teenager days, Back in eighties I was listening to VOA and Radio Kuweit and I was recording mostly on east-german OR-WO tapes (that were quite decent) because the BASF and Agfa were in shortage. Western music reached the black market usually by pilots that were operating civil …

I ordered some ferrite beads for a RF circulator project I currently work on but these might also be very handy for the SWR bridge project. These are extremely efficient for RF supression, or at least this is what they say.
