    Si5351

    I've never had any issues storing these things out in the open. They are NOT that delicate, lol! As long as you don't expose them to anything more than normal humidity, I doubt you would ever have any issue at all. As for drift, I've used these in a number of projects, and I've not had any...

    DDS VFO

    The general installation manual from the DDS-VFO website's help page covers how to set up CLK1 for a fixed frequency. CLK2 doesn't seem to be available in the DDS-VFO menu, but since the 5351 uses I2C for communication with the kit's Arduino Nano, you could probably install and connect a 2nd...

    Favorite tech for repairing board trace?

    The radio in question uses a double-side board. It may not be a simple fix in this case, as a board via may have been damaged as well. Would you be able to take a close-up photo or two of the damaged area? Might help with coming up with a solution.

    Shure hand mics

    I'm currently using an ancient Turner handmic that was supposedly based on a Shure, but the model is obscured and I have no idea what Shure model it was supposed to be based on.

    Realistic TRC-450 new in box will it work?

    Be thankful they were DEAD! I opened up a Cobra 29 LTD Classic about 20 years ago that was FULL of LIVE roaches. It was just like a scene from a horror movie. Roaches scurrying across the bench, across my lap, up the cabling, down my legs, and in all directions across the floor. Needless to say...

    Another new(?) Ranger

    Great post on the details of that RCI case! I remember when that was a big topic of phone conversations with Galaxy and a few distributors at the time. RCI IS repacking some of the old tech while introducing new models. The problem with RCI is still build quality. I continue to see new Ranger...

    President George FCC - CONFIRMED!

    MSRP in the US will be in the ballpark of $270.00 - $300.00, with dealer cost approaching the $200.00 ballpark. One popular US distributor called me a couple days ago asking my opinion as to whether they should start carrying it, and I had to say no. Not sure this one will catch on very well at...

    Navaho TRC490 No Transmit (PC385AG)

    The part to which Doffo is referring is the AM voltage regulator. Based on the fact that you are seeing proper voltages on the driver/final collectors, and the fact that you do hear the transmit on a nearby radio, I do not think there is an issue with the AM regulator. This is beginning to sound...

    Any more on Mike of Mike's Radio Repair?

    Something fairy major had to have happened, but no excuse for not returning customers' radios, fixed or not. I'm going to try to connect with him via QRZ or maybe bump into him on 2 meters, and see if I can find anything out.

    help with SSB output

    One other broad-banding trick is to put a 200-ohm resistor across pins 11 and 13 of the SO-42P TX mixer IC. I think those are the correct pins, I'm not at the shop to check my notes. I know its two pins near the connection for L47.

    Connex CX-3300HP Hot Am Mod and Finals

    The may seem simplistic, but with the RCI build quality issues lately, look for bad solder joints in the output tank circuit. I've seen a few of these come through that were basically brand new with tank circuit coil connection failures. Any breakdown in the tank could cause the problems you're...

    radio and amp matching....

    I'll add one more observation to the thread. Many newer exports have separate AM and FM carrier levels. As had been pointed out already, you should use the same carrier level on FM as on AM to avoid releasing the magic smoke.

    I know its an older model, but the receiver (especially the noise blanker system) on the Yaesu FT-100 is quite good.

    Uniden Washington Base Station

    I used to believe that braided was better than solid because of the surface area. A well-seasoned and well-educated fellow ham in my area told me that a plain old copper wire, the larger the better, works just as well if not better for RF. Cutting the coax can and usually will affect what the...

    Royce 619 PLL Unit Schematic Needed

    Bad news. Turns out that the radio had more problems than I thought. After substituting a generator for the VCO, I found that the receiver IC was bad, along with a couple other things. 'Nuther parts radio I guess.... Anyway, thank you for your help!
