The DX Engineering brackets are for a 7/8 element. I have some black
insulated brackets from the old N0XX/7 DX Engineering company that attach a
5/8" diameter element to a 2" boom which may work.

The element brackets used on the 6m beam are identical to those on the
KLM 10m yagi.
Had 6 of them here ... sold some .. not sure where the rest are
located. Probably in a box in the garage.

I don't know if this is a coincidence Mike but check out this ad on QTH.

*ANTVHF - KLM 6 meter boom/element brackets*
Have 10 of these element to boom brackets. For both 10 and 6 meter yagis.
Approx 7 in wide. For 5/8 in element I believe. Make offer.

We recently had our utilities run underground to resolve some problems. Left is a coil of 5/16" diameter stranded aluminum power line, about 100' or more. Twoof the wires are black insulated, one is the ground return.
Is this stuff suitable for guying a tower or making a "last forever" wire antenna ofsome sort?
Would enjoy hearing responses to this.
TIA,
John

Not so great as a guy wire (very little strength compared to steel)
probably last forever as a wire antenna.
Aluminum has higher loss than copper, but big diameter makes up for a lot.

As long as the antennas is not very long.. Sounds like about #6 or #4
lead which is nearly dead soft. There's a reason they hang it from a
messenger for overhead lines. We have 00 underground, but it's copper to
the meter and Al from there to the panel. The Al fed with 00 Cu is
really big.
OTOH there's no reason not to give it a try unless it goes over a power
feed.

Anyone know if a G1000 rotor and G2800 control box (or vice versa) are
compatible? Not necessarily for long term use but for a bit of debugging.

The voltages are compatible. Be aware there are SDX and DXA versions and
you might want to do some checking before just connecting them together.

I wouldn't trust it as guy wires. The wire is intended to conduct current.
If you open up a little of the cable and "mess around" with the wires you
find them very brittle. If they left some 5/16 galvanized steel, that's a
different story.
To use it for antennas should be OK, a little heavy though. You will notice
if you stretch it too hard.

I've got a pair of crystal filters I'd like to know about.
What do they fit and what are they worth?
#1: Fox-Tango YF-455H2.1 455 kHz New in the box
#2: International Radio Inc. 88H400 AC
....FREQ 8830 kHz Used, with coax, capacitors and resistor.

My 88H400 came with a small PWB that plugged into the Kenwood TS-940, among others.
In general, it was sold as a higher-performance (i.e., steeper skirts) replacement for the 500 Hz stock Kenwood high-IF plug-in filter.
The value of yours probably depends heavily on whether it has the Kenwood adapter board with it.
Bud, W2RU
The 88H400 has a small PC board. I had a TS-940 many years ago and this may have been used in it.

Tim
