Well, I ran into a bit of difficulty this afternoon when I tried to use my new TinyTrak with my FT-60. As it turns out the cable that I use with my Piccon also works with the TinyTrak. I was excited to be able to use the HT instead of carrying my spare FT-8800 around in the truck. Unfortunately the TT3 wouldn’t key the radio.
I just chalked it up to some misconfiguration between the radio and the device. I read through the manual while waiting to get my hair cut and didn’t see anything out of the ordinary. No funky menu settings I may have missed other than disabling Rx Sleep.
When I got home I checked the Byonics site and looked up the cable again to confirm that it should work. That’s when I saw the problem. With the cable for the mobile I had to leave R8 out of the circuit. In the description for the HT cable it says that R8 has to be IN the circuit.
Byon actually addresses this scenario and describes adding R8 to your cables. Well, that’s all well and good if you’re building your own, but I was using one of his. So what could I do? Well, the lightbulb went on and I used the same solution I’ve used for other kits where I needed removable components…I added a single in-line package (SIP) socket where R8 goes.
Now if I’m using the HT I insert R8. If I’m using the mobile I remove it. This is what it looks like configured for the HT. I had to bend the resistor leads a little and lean it over the pots to get the top of the case to fit but there’s plenty of room now. I tested it and it works great.
I’m pretty happy with myself and the mod. 🙂 See ya on APRS!
