My first job in the business was as a service tech for an RCC. We had a GE

selector switches, and one block on 1000 numbers. In addition to the GE

eliminate the need for the extra couple of sandbags in the trunk in the
winter. TLD-1100 comes to mind but that was the VHF version. Based on a

Depends on who you ask really. The impedance of what most people
call a classic folded dipole is about 300 ohms. But measure the
various dipoles by Decibel and Sinclair you'll probably find they
are not all standard size dipole

That sounds about right to me Nate. I have a repeater with a low
antenna (abt 65 ft) in the flatland around the Dallas area that does
about 12 miles, so not a bad rule of thumb for that low antenna. But I

Dwaye,
I would like the S1056A with the interface cable. Let me know how you want to
do it. Tnx

Subject: [Repeater-Builder] Motorola test set
I don't remember if it was the Pulsar 120 or not but I did indeed
build a repeater in the late 70's, based on a Pulsar. One channel
element (square "copper" as I remember) and a 5 mHz 1st IF made it a
piece of cake. It worked surprisingly well for what it was. As this
was in SoCal where UHF spl

Hi,
I've got a couple of the older Motorola test sets that need to find a
good home. These are S1056A. One has the interface cable and one has
the crystal set strip.
They go for about $10 on e-bay, so it's not much of a value. Just
thought I'd check here to see if someone wanted one before th

Great to see someone describe the Pulsar well. They came into
the SF Motorola Service Station well through the 80's. I don't
remember ever having to really repair one other than small stupid
user things and some control reprogramming.
