Re: [AFMUG] odd Force 200 backhaul issues.

I've seen that happen before, but I can't remember what we did to fix it... I think we may have had to replace the radio. I can't remember if it was a PTP or PTMP situation, either... it was a while ago. It might be worth switching it to TDD PTP mode instead, and see if that helps. On Tue, Dec

Yes de-registering the link does make the link start passing traffic again although it seems a lot shorter lived so far. Only lasted an hour. From: AF [mailto:af-boun...@af.afmug.com] On Behalf Of Brandon Yuchasz Sent: Tuesday, December 04, 2018 7:56 PM To: 'AnimalFarm Microwave Users Group'

I discovered that the 240 VAC line coupling cap only has about 25% of its rated value. Most of the voltage was getting dropped by that cap. So once I get the replacement part, then the whole circuit can get proper power and we will see what voltages we have at the different places in the

Re: [AFMUG] OT Linear Circuit

I have spent several hours going over it. I photographed both sides of the board, edge detected the traces, flipped them, made them white and overlaid the component side. Then manually traced them and drew the schematic. The things connected to REF OUT are the inputs of two different op

Re: [AFMUG] odd Force 200 backhaul issues.

You may be surprised at what you may learn once making contact with them. There are alot of unknowns here so the more you can elaborate on the details of config and such would help the list to define what may be the issue. Also, The cambium forum is a good place to open up for discussion. I

Re: [AFMUG] OT Linear Circuit

Are you sure you drew it right? It’s not making any sense to me, especially with REF OUT being an output. I see a 3V virtual ground, a 100K positive feedback maybe for hysteresis, but that would assume this opamp is acting as a comparator not a reference generator, and REF OUT would be in

Seems like one of those resistors is the sensor? To me it looks like the output is going to try to stay just over 3V but will lag ‘ref out’ up or down if there is any voltage on it.I can’t recall if op amps can sink current or not. The wife was annoyed that the contractor blew up the new
