I've seen the same thing with 3 5/8 or whatever that size is. I figure it
was high SWR combined with something else, but it actually burned it about
40' up the tower as the 'technician' was tuning the transmitter. We later
climbed up, cut it off above the bad spot, installed a coupling (monster
Has anyone used the TC4049BP hex buffer converter chipas an alternative to open collector NPN transistor COR inverters. I'm curious because we use such a chip with our RLC-4 controller and it works flawlessly. This chip has 6 input/outputs with a reference common voltage. There is another chip
The IC you speak of is a standard, run-of-the-mill CD4049 CMOS hex inverter
and the 4050 is a standard CMOS hex NON-inverting buffer. The TCP prefix
just means they're made in Japan :-)
Both of these ICs have been around for 30+ years and is fairly old

Right Ken, You're question of WHY would anyone use a chip when a
transistor an one or two resistors would do is a good one. the only
answer that I can think of is that the person using it doesn't know
how to do it with transistors. Actually with a EXEC II and MVP (and

Brian,
The GR1225 Desktop Repeater uses the R1225 transceiver, which shares the
same RSS (HVN9054) with the P1225 and M1225 radios.
The RX light will always flash when there is a signal on the channel, but if
the PL or DPL doesn't match, you will not hear anything, nor will the signal
be
Mark,
The TPRD-1454 is not a bandpass duplexer; it is a bandpass/bandreject
duplexer- quite a different animal. With a 600 kHz isolation of 77 dB, it
should perform satisfactorily on 2m with a tube-type PA. The data sheet is
