There may be some dependencies on the grid needed to use your favourite radio communication mode(s).
I have never had an outdoor HF antenna until now, and what a difference with the same antenna outdoors versus indoors. I managed to hang an OCFD antenna for 40, 20, 10 and 6 meters in a very small crowded lot.
You do not need a DMR radio to get into a DMR network such as BrandMeister or TGIF. You can use C4FM, D-STAR, and others with some simple configuration on Pi-Star.
With a bit of organization, you can avoid the frustrations of loading saved programs (wav files) into pocket computers or other vintage computers.
I upgraded the Kenwood SP-230 speaker using the Phits K95A and Phits GPH-X80 kits. The new speaker and foam made quite an improvement in detail and sound quality over the original speaker.
I recently acquired the PC-4 printer and cassette modules and wrote a version of my banner program for this model pocket computer. With only 544 bytes available, it was the most challenging version to code.
Recently I’ve been curious about the TRS-80 Pocket Computer (the PC-1), the first pocket computer Radio Shack sold. I was able to find one on eBay and replace the LCD.
I found a deal on a Kenwood MC-50 Desk Mic for my TS-530SP or TS-830S. All that was needed was a new 4-pin connector and the mic worked perfectly.
The PC-6 was the best (in my opinion) rebadged Casio pocket computer Radio Shack sold. I built a cable to connect the PC-6 to the FP-12S printer and updated my banner program using only 909 bytes of memory.
