Re: base insulator

Heard back from Austin--reasonable price. Got to wait until the end of the month--church selling their AM & can't have full congregation meeting until that last Sunday. The Rohn tapered base section --listed as a 55TG1A--is supposedly designed for this insulator. Will be an interesting project, las...

Re: Replace Car Radio Antenna?

I just bought a 2008 Dodge Nitro, great car and looks.I like it a lot. It came with a Am/Fm/DVD radio and has satellite radio too. The antenna is a puny rubber duck mounted on the rear of the roof. Seems to work ok but could it be better if I install a 30" whip on the fender? I don't use the satell...

Re: harris gates one retune

hello can some one give me some advice if it is a lot work/cost to retune a 1995 harris gates one from 1120khz to 1000khz, or does some one have a manual for retuning it (for me who has no expierience in retuning a gates one) It can be done but you need to understand the theory of this transmitter ...

Re: Is my Rate too high or is the owner high?

I have been working as a contract engineer for some stations in my state for about 5 years with a $120 retainer and a $120 site visit fee. I was asked to take over chief duties at a station in another state and 2.5 hours one way. The station is in an isolated part of the state and no engineers live...

Re: What does it cost to replace an AM tower these days?

Hi Braintrust, I'm going through our yearly insurance review and I was hoping to get some vague general ideas of how much it would cost to replace an AM tower. I fear we've vastly undervalued out towers' replacement costs should we lose one to an ice storm or a lawnmower vs. guy-wire. We have 3 bas...

Re: What does it cost to replace an AM tower these days?

You might build a ground system yourself for $6k if you are willing to work for free and have no equipment to maintain but figure 3x that ($18k) if you are hiring it done by an out of town contractor (ie, me). $6k won't cover materials and expenses for a reputable crew for even a high freq ND GS.

Re: What does it cost to replace an AM tower these days?

I had to work up a budget for a new station on the upper end of the band for a 150 foot lattice tower: 150' Rohn62 - $17,000.00 Erection and installation - $7,000.00. Don't forget a new grounding system: $6,030.00. You might try contacting these people for a more recent estimate of specific type and...

Re: "Family Hears Music & Preaching Coming From Bedroom Walls"

It is not surprising if some questionable electrical connection in the wall was acting as a diode. I had heard (but not verified) that there was an undocumented and illegal (according to current NEC codes) junction box behind the wall in the area of the audio source. There are stories of farmers in ...

Re: AM Revitalization Idea.

For comparison, I had an Experimental Station License for On-Air testing of an emergency/backup AM transmitter I was designing and constructing. I was authorized by the FCC to transmit on 1650-1710 kHz with a power of 9.5 W (ERP) with emission type of course being 40K0A3E. The antenna was a base-loa...

That's really sad. When I worked in the sales office in Quinky in 1965-1967, we were supporting stuff clear back into the late 1930's. In fact, not. bragging - of course - I helped a guy out on a very old AM 500 watt rig getting pars to get him back on the air. I made a comment of my age and the xm...
