If you have it then shorten up pin 3 and 6 and plug it. This is a solution if you do not have the supplied 6 pin mini din adapter (basically this is Kenwood's adjustment jig). First of all you have to connect a small copper cable between pin 3 and 6 of the Data 6 pin mini din. Kenwood TS-480 SATe tx power setup. Kenwood TS-480 SATe TX power mod.
![]() Kenwood 480 Mod License And Call10 minutes of research and $35.00 later, and I was well on my way to having a Bahamian Ham radio license and call sign – C6AJB.Like many Hams, I have a very hard time parting company with my toys – even when they have been replaced with new toys. Sure – there will be more than one romantic stroll down a (hopefully) moon lit beach, but then what? I don’t get the sense that there is a lot of nightlife (not my thing anyway), and the idea of wasting my evenings watching TV was unappealing.Then it hit me! I’ll bring my ham radio. At first, I wondered what we might do in the evenings. We will certainly enjoy exploring, swimming and checking out the assortment of restaurants.Lets not loose sight of the fact that we’re really NOT using these things for what they were actually designed to do, so you really should temper your expectations! The simple front end filter was all but worthless towards stopping strong, unwanted signals, and the SDR was easily overloaded. In order to receive frequencies LOWER than this, you need a model that has an “up converter” that shifts the lower frequencies upwards by 50 to 100 MHZ.I bought a regular unit, and a model with an up converter circuit, but I wasn’t exactly impressed with either one. Depending on the model, it will get down into the range of 20 – 40 MHZ.Kenwood 480 Mod Manual Vhf Fm![]() This is fairly common connector – and it didn’t take long before I found a junk donor board that had one. Signal – before – it goes into the roofing filter.I started by sourcing a cable with a suitable 2 pin connector (see the photo – above). I decided to tap into that signal, present it to the antenna connection of the RTL SDR, then tune the SDR to that frequency, and I should be able to see – and hear QSO’s above and below whatever frequency the 480 was tuned to.After reviewing the TS-480 service manual, I was pleased and surprised to discover that Kenwood was nice enough to include a simple 2 pin connector on the RF board (CN152) that provides a sample of the first I.F. Frequency runs at 73.095 – well above the minimum frequency of any RTL SDR dongles. Circuit – IS – the up converter.There are other benefits that will become clear, later.The TS-480 1st I.F. Mazda b4000 truckIt should also work with VHF and UHF gear too.Stay tuned for part 2 when I chronicle the set up process.BTW – the contact form on this website is broken. Though it’s not quite up to par with my Flex 5000A, I think it’s safe to say the results are pretty respectable, And you DAMN sure cant beat the price!Though I don’t hear any evidence of signal degradation in the 480 with the addition of this mod, I’m still considering adding a buffer amp – perhaps with just a little gain – in order to achieve increased isolation and give the SDR a slightly hotter signal.Finally – for now – this process should be possible on most ANY make and model of modern Ham radio equipment. This plan seems to have worked out well.The cable is secured to the shield with a wire tie in order to prevent accidental disconnection.After firing up my favorite SDR software ( HDSDR), I spent a considerable bit of time configuring it. I think that’s a much better option than to trying to fight an odd ball connector onto the tiny RG-174 sized coax. I opened up one of my RTL SDR dongles, unsoldered and removed its RF connector, then dressed the bitter end of the cable, and soldered its leads directly to the board where the connector once attached. Carefully soldering the leads from a short length of RG-174 directly to the pins would be perfectly acceptable.After removing the cable from the donor board, I pushed aside the screen material and routed the end of the cable out through one of the vent holes on the 480.
