Parallel Batteries

Not broadcast related, but basic electronics. Circuit design was never my strong suit, but I want to parallel two 48V lithium battery packs for my e-trike. Both packs will be the same rated voltage and capacity, but I want to allow for variances on discharge curves without one pack feeding the other...

Re: Radio Systems Millenium Digital

Try Angry Audio. They bought the Studio Hub line and got the inventory of Millennium parts in the deal.

Re: Simian - Flex Time Help

My first thought is are your spot blocks configured to the proper length? It has to know the total break length to stretch/squeeze. This is done in the clock for the hour for most BSI software. If a break length is not set, it won't try to adjust. Using the @ to specify the times in this case sounds...

Re: Antenna Recommendation - 2 x Class C Omni

I'm interested in the responses to this topic as well. I have two C's 5.4 MHz apart on the same tower with 35+ year old antennas that the idea of replacement should at least be on a future timeline for replacement. Both are fine right now, but we hauled one of the bays down to braze over a lightning...

Re: RDS Via Moseley StarLink

I think mine was on 1200,8,O,2. There are DIP switches on the audio cards to change it. I set mine to 2400,8,N,1 to make it something easier to work with. And yes, I did put a nice big label on the back to denote the change.

AM Consultant Needed

I need to hire someone that is within a reasonable distance from SE North Carolina to do the measurements, redo the ATU as needed, and float/detune two towers that will no longer be used. Taking an AM that is licensed for 5kW Non-D day/5kW 3 tower DA night to 5kW Non-D day/85W Non-D night. PM me if ...

Re: EAS FM Receivers

Ended up ordering a Crown RFBA. We can capex the Crown, but not the Dayton's at Bay Country. https://www.crownbroadcast.com/receivers/rfba/ I looked at the 3 pack from Inovonics, but they were $550 more than the Crown and only single band each. The Crown will receive AM, FM, WX, and 2m FM on all thr...

Re: EAS FM Receivers

Thanks for the tip on Bay Country for the Dayton's. $495 for a triple receiver is not a bad deal. Gonna approach the boss on it. How's this for a tough receive, one of the monitoring assignments for my LP1 is a class C FM about 100 miles away that has a 1st adjacent class A locally. It is the region...

EAS FM Receivers

I was messing around today redoing the EAS setup after relocating the Sage units. Powered down the old TFT 930A's to make the audio feed into the the 2 Sage nicer and relocate it in the rack. Got it all done and now only one of the 4 tuners works. And I need 4 as one of my stations is an LP1. Seeing...

Re: Elenos ETG 3500 transmitter questions?

The nice folks at BE in Quincy can help you out. Elenos owns BE now and runs their US support from there.

I have a couple of older Continentals running their ETG1000 as an exciter/IPA. Work and sound great.

Re: Moseley "soup can" isocoupler

Thanks, folks. They are of a higher rating than I would have thought. The calculations point to a an RMS voltage of ~400 volts, so we should be good with even peak modulation voltage. That all depends of course the impedance being somewhat close to the 32 ohms measured way back when the array was se...

Moseley "soup can" isocoupler

Does anyone know the specs on these? How much RF will they handle? The demise of another marginal DA is coming up soon. Plan is to just go flea power at night and put the savings from not fixing the array into the translator. The thing is, the current day tower is the far tower all the way across th...

Re: Harris Z16HD

One thing to be aware of in the Z series is that the compression connectors on the ends of its MANY ribbon cables can start to go intermittent with age. The IDC pins tend to develop a touch of corrosion and undesired things happen. Just something to keep in mind if you get a wonky problem that makes...

Re: Marti STL-10 regulator

I don't even bother fixing that supply anymore, you can drop a 15V 4a switching supply in there for about $25 and have a lighter, cooler, quieter unit. It also eliminates that nylon header connector that fails over time. This is the advice that the late gentleman that did Marti repairs out of the o...
