They aren't rare and they aren't 8-32 either... not in mine. 6-32's here. Any old piece of gear that has a terminal strip is is a likely source to rob one from.... and as others have said, they are e
Since you asked..... the Alfa Spid mid size RAK (and the smaller RAU unit) will fit in these towers, according to customers feedback. It's a tight fit, you'll need to use the taller mounting base to
I wouldn't give up on the old nut so quickly - I would think that your favourite brand or homemade concoction of rust penetrant (give it time) coupled with heat from the torch (the one you might have
An experienced local MW broadcast engineer and low band ham, VE6LO now SK, did some experiments with radials on a 160m vertical he had with a yard that also had obstacles. Using a RF current meter (s
Hi Gary; Just a small correction - the Alfa Spid is actually made in Poland but with much input from us in Canada (Alfa Radio). For mounting outside of a tower like you describe, it's something the R
Yes the RAK (or big RAK) model rotators are well suited for side mounts as they are easily mounted on a standoff mast... very easy to make - 2 lengths of angle iron, 2 short pieces of pipe and a slee
Hi Phil: *The manual I have for the controller states that rotor terminals 1 and 2 * *are for Motor CW and CCW and the Ground and Positive are on rotor terminals 3 and 4.* 3 and 4 are sense wires and
Have certainly seen similar things here.... likely a coax connector not quite tight or has oxidation - but usually a small dose of transmitted RF will break thru the oxidation layer and make it work
The liquid tape I used was also useless... peeled off under the Alberta sun in no time. If I need to cover stuff with a spray, I use the red HV spray from SprayOn (# B-6-665) It's like Glyptol and is
2 or maybe 3 wraps (nice and snug) not layers is what you want... _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@cont
The Canadian version by Delhi (now Wade) is similar but has the 5 X braces. Perhaps he has one of those... _______________________________________________ ____________________________________________
The early Delhi's had the similar swaging... The common term around here is the necked or "Coke Bottle" style vs the newer continuous taper. _______________________________________________ __________
Not to answer your question directly, but if it were me I'd forget about swaging anything and just shim it. And I have done so on several occasions. Worked out fine. 73 Don VE6JY ____________________
I'm not sure of anything in Alberta... most commercial guys want big orders. There are/were places like Metal Supermarkets but usually also $$. I'd look for a fellow local ham with scraps, you won't
Hi Richard, Yes the rings are available from our store in Edmonton Alberta, 2 sizes available for Rohn 45/55 and for 65. We had one of each ready to take to Dayton this year so they are available. Yo
Tektronix 1502 TDR or equivalent..... no connectors needed. Measures the length pretty well too and sees any impedance flaws. Especially bullet holes. _______________________________________________
It's a pain even if you only have to remove it once... I use the Cinch Jones plugs for everything, while not waterproof, they do fine when protected from direct rain etc, like inside a bigger box etc
If I don't have to lift very far, a suitable turnbuckle works well and can get in the tiny spaces. Along that idea, a loadbinder (ratchet type) also would get it done. _______________________________
They are essentially the same. At times during the production cycle the AlfaSpid might have certain changes we (ALfa Radio) have requested for the North American market. _____________________________
