Local tech here made something along those lines for a 80 yo diabetic whos sight went so bad he could only tell dark from light and couldnt use a phone or computer, and could not see channel numbers on the radio, think it was a uniden grant. No talking numbers, but 1 short beep when he landed...

I mainly use it on receive. If splatter or bleedover comes crackling through the speaker because someone close or with big power is interfering a flick of the switch brings them in clear without having to click through the channels. I can then turn wideband off and change through the channels...

No, it receives on 15 channels at the same time when the wide band switch is turned on. If there are people talking on say 30, 33, and 38 they all come through clear at the same time, just like they are all on the same channel, if the modded radio is on any channel from 23 to 40. Loz!

**** re-post from earlier thread on the same subject **** Found this mod in an old GE A model we bought at a yard sale. GE was rusted out dead beyond repair it had been in a wet barn for decades. But built a new circuit as above and put it in a working cybernet base radio. And it works real...

One mod from a year back on T1 for the cobra 29, gives low 40, high 40, 5kc shifter switch and 10kc shifter switch with $20 worth of ebay parts. https://www.transmission1.net/viewtopic.php?f=53&t=56500

Two of them were my radios, one was a Hornet which is an aussie rebadge of the cobra 142 or 146, cant remember which one, the same method also works for the uniden washington and the side mike cobra 148 and other uniden made ssb radios with the 16 pin transmit mixer chip. It involves seven...

Mentioned this tonight to them on t1, they said no request has been received by email, priv msg, or in the t1 forum. Cant help with the technical stuff on method of operation it's way over my level, can pass you on their direct email address in a pm if you like. They did a similar mod in my...

One of the local techs here did a Cobra 29 for one of their customers in the USA (they had to send a radio here 'cos cb radio down here is ssb only). Posted with all the technical details with pics (way over my level of understanding tho) on the trans1 forum. Cost was under $20 with currently...

The young 'un uploaded the video to youtube for me and the technical stuff about the base is on the t1 site, most of that stuff though is way above my level but radio works great bang on freq and no drift detectable by my ears, supposedly 1.5 hertz off but sounds fine to me...

Couldnt pick it by my ears. Anyway it got better with age, it drifted back 1 hertz the other way so now its only off by 3 hertz, close enough for me. Got the krako ssb de luxe base back today from its 40 channel plus conversion, its drifted from cold to hot by 1.5 hertz, a bit better than the...

There is only one place left in in Oz to buy a decent antenna: http://shockwaveantennas.com.au/ Ive had one of their 58 / .64 antennas for about 5 years, getting about 40-50km local coverage and daily 9+ to the east cost nsw / qld from here (kalgoorlie wa) using 12 watts. Mounted about 4...

Oops, forgot the magnum link, here it is: Magnum radio working, over 50 watts out

That's about a 5 day drive from here, so won't be calling in there :D Plenty on the Oz ebay site though. Basic but working 40 channel ssb pearce simpson Magnum radio working, over 50 watts out Kenwood ham radio 100 watt working, looks like it covers 27 megs If you are on more of a budget...

Adding to that, will be in the north shore area of sydney in a couple of weeks, start of december ish, if you are there can let you know whats around and roughly how much.

Where in Oz are you? There are a few locals here selling grants and cybernets and similar, and a few more on oz ebay too. Try searching for "ssb" on ebay. We are at kalgoorlie boulder in wa. If you are near there can ask whats around. Loz!

Tech said it was more likely to be temperature variation but in the end it was not worth losing sleep over because my old ears cant pick a 4 hertz error so we left it at that. Good enough for me. Next radio currently being done is a kraco ssb de luxe base radio from 1976. Apparently it...

They said the drift was from the 10.240 crystal which is outside of the TCXO control. They offered to fix it but we declined as neither me or the others on the channel could pick it by ear. Moved on to my next radio now, 42 year old Kraco.

Just dropped a Kraco 23 channel base to tech in excellent physical condition but completely dead (no power getting through and a faint burned component smell from inside). Asked them to convert to at least 40 channels (oz call channel is 35 lsb so a 23 channel radio is useless down here) and...

Just got back from month long vacation road trip, 4 states with a 4wd and trailer through both desert and tropical areas of the country. The radio was measured again when we got back and it had drifted 4 hertz lower, so average one hertz a week. On air most people said i was spot on freq, but...

Measurements of frequency with temperature: -4Hz @ -10 degrees C (14 deg Fahrenheit) for 3 hours +1 Hz @ +20 degrees C (68 deg Fahrenheit) for 3 hours +7Hz @ 60 degrees C (140 deg Fahrenheit) for 3 hours This was done in an environmental chamber and measured with a rubidium referenced Agilent...
