I've had some progress tonight. Two simple mistakes I should have avoided. First, the mini-stereo socket I used for the homemade OPC-592 adapter was a mono jack. The third pin was for audio muting

Sorry I can't solve your issue, but any Icom gurus responding to you may know about my "Revision B" problem when I try to read one of ,my IC-4000-3 machines. I ended up using it as a donor for parts

Tim, I sent you a reply to your last request prior to seeing this - I suspect it answered some of your questions here. You program using the 25 pin receptacle through the handle.? Aftermarket

I never worked with an IC FR4000 and I had a request to help a group of ham make a DMR repeater from a FR4000. To do it, we need to have flat audio in and out. and I was able to find the information

Yep, that will work fine as a minimum center to center distance on 6M. Just no guy wires between or within 5 ft of the antenna elements, especially above the top element. (We were forced to have

Mike, I have 3 of them. I will send you a direct email <mwbesemer@...> wrote:

The WACOM WP-641 provides 93 dB of rejection at 1.5dB of insertion loss at 600 kHz - if it's a UHF connector version.? If it's an N connector version the rejection is 91 dB or so (yes it's less).?

I'm looking for a 107.2 Hz Vibrasender for an MSR2000. It looks like either the KLN6210 or KLN6824 should work. 73, Mike WM4B

Hello Group, I thought this task would be easy. But the more I delve into the programming the more confused I become. Here is my situation. *Radio* Astro Spectra-T04KLF9PW4AN (1 meg 2.5 kHz) I don't

I still love my WACOM WP 641 that I bought new back in 1983.. It's been retuned a couple of times to new frequencies and it floated in tropical storm Harvey water for almost 3 weeks as the site was

Kind of a tossup, similar specs for isolation @500KHz but the Sinclair advertises .1dB less insertion loss per leg. The Sinclair seems to be a current product where the Wacom would be getting quite

Good evening all, I'm having difficulty reading two (very dirty) Icom FR-4000-3 repeaters that I recently acquired for rehab. My software is CS-F3000 version 1.1 and I am using a genuine OPC-478

I have both of these duplexers available to replace an existing system. The site itself is a water tower with an existing DB224 that has been made available to me. It is mounted at the very

I think they should be on the same side of the tower 12 feet apart. My frequency is 53.050 input is 52.050

If the coax to the T is 50ohms, then yes , an electrical 1/4 wavelength of 35 ohm coax from the T to the feedline. You could less ideally alternatively do two 1/4 wavelength 75 ohm coaxial cables

Got a picture? Is it a DB212-2 or home brew or what??? [email protected]> wrote:

A common problem is that the USB-serial adapter will be assigned a comport number that the software will not show as available to use. Joe, K1ike
