Just ordered a 4CX3500A rebuild today from Econco...apparently they had stock, as the tube shipped today.

The Skylla automation has a very good RDS interface. And I believe their support folks would be willing to make custom tweaks if necessary to work with your new encoder. I have a group that uses BW Broadcast RDS encoders. I sent them the manual pages that refer to the specific commands for these box...

Not sure if this is the right place for this...But looking for recommendations for a crew that can handle repair of a high intensity strobe light system other than Strobe Tech. The tower is in southern Indiana.
I wanted to post a follow up to this thread. At this point I am "knocking on wood", but it looks like I might finally have this problem resolved. The problem appears to have been an intermittent screen supply breaker in the HV cabinet. I enlisted the help of another engineer, and we tore down the gr...
A quick question...does anyone know what kind of rigid coax the output transformer is made from on an EO 300W IPA? The circuit designation is T2 I believe. The one I have uses the MFR151G FET. The center conductor appears to be intermittently open in the one I have on the bench currently. The IPA is...
The coax on my unit is the upgraded RG400, and is in good condition, but it is one thing in the circuit that has not been changed. Still having issues. Most recently, the transmitter was brought up having been off air for four days, and ran perfectly without any re tuning necessary for about 18 hour...

Very interesting...one of my client stations just commissioned a new WIN7 based Storq system last month...Not my favorite program delivery system, but they work. I was a little confused that they sent one, as another station in the group running the same format had moved off the Storq onto the iPump...

I take care of two groups that utilize Gorman/Redlich EAS equipment. I was just filing Form Three for the recent NPT, and while reviewing the logs, noticed that these boxes did not process any alerts from the internet via IPAWS. I have not checked the CAP-DEC-1 unit logs, but the test was not proces...
Thank you to all who replied. To answer some of the questions posed in the responses: I don't know what the BW transmitter is seeing when the IPA overload condition happens...It is about four racks away connected by a RG-8U jumper. When the 25K senses an overload, it interrupts power to the BW unit ...
I take care of a FM-25K that I am pulling my hair out over. It is about 100 miles away and has a very intermittent condition I have had no luck in addressing. The transmitter is configured to use an external BW Broadcast 600W box as the driver. It is properly interlocked and controlled by the 25K, j...
Thanks for the responses. The failed fuses are always a non-catastrophic failure, just barley melted. I don't believe normal current draw is a problem, as I briefly replaced the 3A fuse with a 1A fuse, and the transmitter ran for about 5 minutes before I swapped it out for the proper size. At this p...

I take care of one of these transmitters, but don't know if the exciter manual is still on site or not. I may have the chance to drop by tomorrow, and will get back to you if I turn something up.
I look after a 1KW EO Pulsar that has a strange problem. In the exciter chassis, it will occasionally blow the 3A +15V fuse. It is a non-catastrophic failure, and the transmitter immediately returns to air following replacement of the blown fuse. Generally, it will run between 4-6 months between blo...
I have used the Sine RFC-1/B for many years, and generally like them. I came across info on the RAK-2 and it looks interesting, as it gives the RFC-1/B a web interface and the ability to e-mail or text alarm conditions. Anyone have any experience with one of these?

FYI...this is a non-comm religious station, and every dime that we have spent has been given as a donation to the project. What I have done so far: I have swept the antenna system with my TG/RLB, and get a return loss of 26 DB at the carrier frequency. Next I fired 200W into the system, and calculat...
