Re: Removing insulation from fine wires
Way back---I used my teeth...
The insulation types available today preclude the use of a single hobby price tool. You need to develop your own method for striping the insulation for each insulation

Re: ?- How high SWR before smoke?
I understand full well about how to isolate the irf510s electrically. However has anyone given any thought as to what may happen, if anything, to the RF coupling if the transistors are mounted on the

Re: ?- How high SWR before smoke?
Google "TO-220 insulator kit". You can steal them from old equipment such as a computer power supply.
With two of those and some heat transfer grease, you can mount the IRF510's to one grounded

Re: CEC firmware with RadI2Cino board?

Jeff -
I thought that this would be fun to try to figure out, too. Did you ever do any further investigation into using the CEC software with the RadI2Cino board?

Re: Current Draw
Hello Arvo,
It is logical to get higher current at the lower frequencies as the gain and power level goes. But a jump from 1.2A to 4A seems too much to be explained by extra gain/power output

Re: ?- How high SWR before smoke?
Hello Walter,
If you can/want to use batteries that are higher than around 14V I would not recommend the RD16s.
Speaking from personnel experience I managed to kill an RD16HHF1 when I forgot to

Re: Elmer in Atlanta GA with working BITx40 RFSignals Kit working
Yes, I was using a 500W radio near the BitX40 and even though it was off and disconnected from an antenna, it fried Q13. So when I keyed PTT it would go into transmit but had no output. Another

Re: Programming error message
Well kept trying and finally got it to work. Was able to get to get the cec software to load and then the original version as well. I think it was either settings in tools or maybe a bad download. But

Re: Removing insulation from fine wires
In a pinch, I have used my lighter. Quickly heat the area you want the strip to start at and then grip the wire firmly and give the insulation a pull. Kids...don't try this at home.

Re: Completed my QCX

If you install the AGC kit you can just use it for the S-meter. Just tap off the first pin where the several jumper pins are for the delay. Works fine.

Re: ?- How high SWR before smoke?
I'd keep any radio under 2:1 for extended period of time. I also abuse that often
so far no fried finals.
However I did some testing today and the cable was on the floor so for 5 minutes
