love it thank you. Im about to send you my TRC 1001, feel free to take it out on your test.

I think the President Randy III is the best out of the modern handhelds from the test videos I’ve compared. It sounded like the bog standard Midland 42 had some sort of pulsing interference on receive where as the DS version was a lot clearer.

Bearing in mind there is an RAF base 2 miles away in one direction & another 4 miles in the other direction we sometimes get radar interference on radios with receivers a bit prone to bleedover. I never heard that interference when we did the servicing video or 'on the air' test with that same set last year. Richard

I like watching richards videos All about radios

I would love to se side by side comparison between the thunderpole tx and the president Randy 2 or 3 i think....i have the thunderpole tx and its a fantastic radio 😎

These radios with rubber ducks just do not give any good range at all. I am surprised they do 1 1/2 miles! Bring back the telescopic aerials, even if they were prone to get broken, But I suppose for keeping in touch with another walkie talkie at half a mile or a mile is what they are for really. Still remember getting a surprise when someone answered me using a Cybernet or a Midland hand held, I was at Loch of Skene and she was in Maud using a Fidelity 3000 base station. I would have put that down as almost impossible. But it happened, I spoke to her for quite a while. She did have a big Silver Rod or something like it. I don't think I would have much hope with one of those!

I remember in the 80s you could get a rubber ducks with a grub screw to attached to the telescopic when it was down to allow you you to use the handheld more easily . or in confined spaces when max range was not required. I imagine the SWR was a bit messed up though

Yes & I have some here. In tests we did in 1983 fitting a rubber duck of the type you mentioned reduced range to just 12.5% of original range. So imagine 8 miles original range then becomes 1 miles range etc. Modern helical compact aerials will now be computer modelled & clearly work better than those of 1981. I haven't compared but have a sneaking suspicion that the aerials on these Midland 42's are the most compact of the current models I mentioned in the video. Richard

Love the vids, this is a big ask, any chance of putting up a small map with your test area and distance please. Thanks for all the good tips

Hello Richard :-), You must know that antennas for portable devices are unstable in frequency, they are tuned differently. Alan 42 antennas are tuned somewhere at 28 MHz so they perform better in the GB band than CEPT. Antennas from other mid-coil devices are also imprecise but are more efficient due to a different design, the coil is higher and there are fewer metal elements around it, affecting the impedance and resonance frequency. You need to get some portable but small physical impedance analyzer, it will help a lot. The size is important because it should be similar to the size of the radio with which the antenna works. The reason why antennas for mobile stations are tuned so high (too high in the frequency scale) is the lack of scientific knowledge, they create them on a measuring table prepared for car stations. Adding a counterweight lowers the resonance frequency and lowers the antenna impedance. So the antenna tuned in this way works at higher frequencies, when it is devoid of a large metal cord, they cannot create for mobile stations, probably from the shoulder of money for training. One more little nuance, each radio transmitter has some typical rated output impedance at which it achieves its designed output power. However, this is just a theory, in fact a 50 ohm transmitter can reach maximum power at 40 ohm or 80 ohm impedance, this is a very complicated process simulated by designing output filters, computer simulators do. Depending on the type of portable radio, it can tolerate low-impedance or high-impedance portable antennas much better. The radiation power will be significantly different, even though the transmitters on the measuring table had the same 50 ohm output power, but for other impedances, these powers will differ significantly depending on the type of radio. Therefore, for science purposes, it is worth measuring the power for 25 and 100 ohm impedance. The wider the impedance range the transmitter offers full power, the better. Health Richard :-)

All that said, however; all walkie talkie radios are field tested with the aerial supplied. Comparison is therefore fair as competetive brands clearly do a better job on tthe aerial design. All the handheld radios (with external aerial sockets) are always tested in our 'in the air' format & both thee sets did the full 6-mile course OK. For the convenience of a compact radio with a compact aerial that achieves 1.5 miles over our range course it's fine. Yes, other compact sets did better & all cost more money. We still can't beat the range of the 1981 Realistic TRC1001/TRC1005 & the metal cased Binatone Long Ranger series all with their huge 1.5M telescopic aerials. In conclusion we do have both MFJ & other antenna analysers, but the point of the test is to demonstrate the radio with the aerial provided by the manufacturer. Richard, G0OJF, UK

The alan 42 antennas may be slightly different from each other, they are one of the weakest antennas I know. I used to have a Sirtel portable antenna and it was also very weak. A large metal radio with a telescope antenna and an adjustable coil is unrivaled because it is possible to tune the antenna exactly to this radio. Health, Richard.

Hi, I've just bought a midland Alan 42DS. On playing around with it I've found when set to UK a long press of the LCR-A/F button changed it from UK to I . Does this have any effect on power or frequency ? It seams to have an effect on the TX bar when keying up. You can also change AM/FM by long press of the sc button then LCR to change. I don't have anyone in my area to test this. Thanks.

Telling the radio you are in Italy (I) puts it into 40 channel CEPT channels only, in AM & FM. When set to UK channels it will do 40 UK FM, and then 40 CEPT in AM & FM. All you are doing is no longer being able to access the 40UK FM channels. If you wanted CEPT only channels & not UK, you can legally set it to CE or EU channels. Yes if in AM if will have an effect on the TX bar as it will develop less power. AM transmit takes twice as much electricity as not only7 does the radio have to produce the carrier, it also has to provide the same power in audio output to modulate the carrier. Richard, G0OJF, UK

Do you recommend a hand set . Unable to get any local support to set up a Homebase , it looks like the Homebase sets itself up regarding SWR . But are Homebase powers by battery still ? . 80s user but trying to get back on channel

@ukfmcbradioservicingTango21

Homebase aerials need assembling as per the instructions & the SWR checked...if the SWR is no good, the aerial has to come down & be adjusted....or adjusted in situ if that's possible. One reason why I use the Antron 99 type as it can be adjusted from the bottom. Bear in mind many aerials...mobile or homebase are made for the American market, so need to be a bit shorter (often 3 inches) for use on the UK frequencies. If you use a mobile (car type) CB radio as a base station you need a mains power supply rather than faff with batteries. These power supplies are made specifically for this purpose and deliver 13.8V...not 12v, therefore replicating the voltage in a car when the engine is running. I know of o UK legal CB radios that draw more than 2.5A on transmit, so the 3-5A power suppies are fine. I don't recommend products especially new ones. The President Randy III works better than the Midland 42DS & the previous Midland 42 seems to work better than the DS current version. We use the cheaper Jopix type here which also seems to work better than the Midland 42DS. Bear in mind I'm in open countryside in a rural location. These modern handhelds work for about 3 miles here...the President just about 4. Those older 1981 handhelds like the Realistic 1001 or 1005 or the Binatone LongRanger 40, 12 or 6 & a few others with the juge 1.5M telescopic aerials achieve 6 miles here. We've had 14 miles on those sets in other easier tests. We get 35 miles in our best direction car to base & 10 miles car to base in our worst direction. Car to car we get between 1.5 miles & 12 miles depending on terrain. I hope that helps you. Richard, G0OJF, UK
