Communications overhaul

Post by taipan821 » Sun Jul 23, 2017 6:00 am

Ok, I'm looking at creating a stand-by communication network to supplement/replace landlines and mobile networks.

my three areas
-short range
-portable long range
-long range base

my long range base is sorted, I'm using a Codan 9323 with matched autotuner and antenna. this allows me to selcall other radios, I've had it modded to also allow me to change frequencies in channels (not standard)

short range comms I'm looking at a couple of baofeng radios, I want dual band to allow us to monitor emergency services (road blocks, fires etc). I also have a TAIT dual-band which I'm fitting to my vehicle/making mobile

portable long range I'm looking for a cheap QRP radio. I'm looking at the Bitx (can it be modded to multiband?) and the mcHF by m0nka. other options are welcome but following criteria are required
-must have voice
-must be compact (smaller is better in a pack)
-must be easy to operate
-must be low power
-must be purchased in kit form (I want to put them together so I can learn about troubleshooting)

Cheap = max budget$$ ???

For QRP maybe take a look at what has been reviewed in eHam http://www.eham.net/reviews/products/22

For the dual band hand helds, if you haven't already settled on a model, I can recommend the UV-82 over the UV-5R.

The -82 is a bit larger as is the keypad, making it more fat finger friendly. It also has a scan feature which none of the -5Rs that I have seen offer.

miklor.com has reviews and info on many of the Chinese ham radios---hand helds and mobiles---, including the Baofeng models.

If communications security is an issue, perhaps digital ham radio might be an affordable means to improving this aspect of preparedness / security.

While I don't have one yet, I've talked with owners of digital ham radios and have read about what this mode can offer and the intriguing part seems to be (if I'm correct) that unless others have digital radios and use the same.....same....protocol ? (i.e. both / all radios use DMR or D-Star) then others won't be able to clearly or easily hear your transmission.

Just a thought......

My UV-5R has a scan feature. It can scan channels or frequencies.

I would go for one of the 7w/8w models rather than one of the 4w/5w models, but the price on the 5w is nice. From what I see one should expect to put in an extra (US) $30-$50 in accessories to get the full potential out of them.

I certainly plan to.
