Configuring TM-D710GA for APRS Indoors

Posted on December 20, 2017 by robert

That last word “Indoors”is the clue… The TM-D710GA has a built-in GPS.  Not surprisingly, it does not receive indoors, and it has no provisions for an external antenna (only an external GPS receiver). I had setup the radio for A-side … Continue reading →

After cleaning the synthesizer inside and out, I replaced multiple screws that were missing from the internal metal frame, and bolted down the power supply, which was obviously replaced in the past (without putting it back in properly).  Despite the … Continue reading →

Restoring a HP 3335A to full operation

Posted on November 11, 2017 by robert

I’ve always been sort of a time nut, but that’s pretty closely related to frequency.  The ARRL helps to sponsor a periodic Frequency Measurement Test, usually held in April and November.  A good friend of mine, John WA1ABI, always participates … Continue reading →

Back in March of 2013, I installed a Diamond K9000 Motorized Antenna Mount. Unfortunately it started acting up about five months ago after about 3.5 years of service mounted on a truck that leaves its garage about twice a week, … Continue reading →

Posted on February 21, 2017 by robert

Of course the Pixie final transistor, Q2 S8050, gets darned hot, and I’ve blown one out in the past just holding the key down more than a few seconds.  With my Pixie + Red Core Filter, I was seeing about … Continue reading →
