Does anyone on the list have or know >of a broken or junker radio, they would separate one from? Way back soon after the earth was first formed and a few decades after the Gonset Sidewinder was invented to promote store-bought 2m SSB rigs, I acquired a TR-9130 for less than a song and dance (had to sing for the thing, but not dance 8-). But it was missing the main tuning knob. I hunted high and low and for some reason, just never thought of ordering one from KW. Meanwhile, I found an old boatanchor Dakaware spinner knob that fit and worked just great. Some 20 years later, I happened to be visiting a friend and lo and behold, he had sitting on his workbench what looked to me like a TR-9130 main tuning knob. I asked him about it. He'd repaired a -9130 for some other guy awhile back, and when the guy came to pick it up, the guy decided he didn't like the stock knob. They hunted around and eventually found another knob the guy liked and my friend installed it instead of the original TR-9130 knob. My friend said he told the guy to take the old knob just in case he wanted to put it back on, but the guy forgot it when he left. Then the guy moved across country after a few months, leaving the knob behind. So my friend gave me the original TR-9130 tuning knob and I've been happy ever since 8-D Odd thing, though; oncit I installed the correct, original knob, I decided I liked the larger, old boatanchor Dakaware spinner knob much better, and reinstalled it 8-P SteveH, K0XP From rick.nk7i at gmail.com Wed Dec 16 19:29:44 2020 From: rick.nk7i at gmail.com (Rick Bates, NK7I) Date: Wed, 16 Dec 2020 16:29:44 -0800 Subject: [Kenwood] Frequency knob for a tm-241a In-Reply-To: <0LgaN1-1kM6xH1X9B-00nxdT@mrelay.perfora.net> References: <0LgaN1-1kM6xH1X9B-00nxdT@mrelay.perfora.net> Message-ID: <73c3db09-aa51-ddeb-9059-20bd885850f3@gmail.com> Perhaps a task for a local 3D printer?

This raises the receiver noise floor when operating in crowded conditions, such as in a contest, and can also cause interference to others when transmitting. I wonder if anyone has done any work to try to improve the phase noise in a TS-440? I am guessing that some time constants could be changed in one of the PLL loops to reduce the phase noise, but there would be some kind of trade off. Perhaps tuning across a band would be slowed down or TX/RX changeover time would be increased. If you know of any such attempts to reduce phase noise on a TS-440 please tell me, or tell me who to talk to.

I have a TS-450 and I?m able to reduce noise quite well by that maneuver.

I bought this radio used years ago, and may not have given it a complete checkout when I received it. It is possible it has been this way since before I owned it. Is there some setup using jumpers inside the radio that determines the offset value? Is a 1.6 MHz offset on UHF a standard somewhere in the world?

As I recall, setting it to the "A" (US) model will also allow cross band repeating that the "E" version does not (mine has been stored for years). Once the mod is (un)made, a full reset of the radio is REQUIRED.

I found the information with a google search on "radio mods tm-732". The resistors relevant to these options are R19, 20, 21 & 22 in the control head. It is really easy to get to them. Don't even have to remove the radio from a mounting bracket since the changes are all in the removable control head. I found mine was configured as E5. I changed it to the K4 configuration and it is working fine with the desired 5 MHz TX offset on UHF. 73 ES HNY DE N6KB On 2020-12-31 10:09, Rick Bates, NK7I wrote: > And to continue on that vein, yes it is possible to reconfigure > (diodes, resistors or jumpers inside the radio) for different parts of > the world.?

So I am resending this directly to the list. Sorry if it gets posted as a whole new subject instead of a follow up to my original post. Maybe I'll figure out how to do that easily.
