↷ On a local Ham Radio Flee Market I saw for 5 or 10 € a Kenwood TR-2300 QRP 2m portable station. It was no batteries pack in, no manual, and it was no microphone with. I don’t know it’s working or not.
But this old TR-2300 are sold on eBay for up to 80€ in good condition and without batteries. So I bought it. At home I saw that this radio was completely destroyed. Some IC’S and transistors fail out of the radios, as soon I opened it. So a long repair is starting.
↶ And kow I need a batterie box. I find one by Pollin for 1 € what fits in the place in the TR-2300. The accumulators are 1.2V 2500 mAh. After a complete alignment of the PLL and the receiver, I hear my first stations on 2m.
I made a break for some days and enjoy the moment.
But no output in transmitting, so far. After some days in the internet I found a 12,5 KHz modification from UK, where the PLL is replaced with a MC145106, that I got from China for 6€ with shipping. So nice, I got a PLL and 12,5 KHz modificatio.
