Puxing 777

This is my second blog post about these dirt cheap handheld radios (VHF and UHF). Over the past year I’ve bought more of these radioes. This time I bought the Puxing 888 that is a better version of the Puxing 777. I dont know why people must bust expensive Icom, Yaesu, Kenwood etc radioes when you can get a inexpensive “china-radio” for under 70$! These radio are maybe not so robust, but I drop my handhelds from time to time and everyone works just perfect today. Another benefit are all the cheap accessories like earpieace, extra battery, desktop chargers etc.

Here you can read reviews on these radioes

Here is a youtube video on the radio

Feidaxin FDC FD-150A/450A – Handheld VHF/UHF radio

Dec 23

Posted by admin in Transceivers | No Comments

FDC FD-150A/450A

The first VHF radio I imported was a Feidaxin FDC FD-150A. This is a 2m (or 70cm) handheld radio. The price is about 60$USD. It’s a full 5 watt transmitter with everything you need. (Simplex, Duplex, CTCSS, DCS, memories..)

for 60 dollars this is a fantastic radio, but some drawbacks are there:

- Poor selectivity. 

- Useless S-meter

- no 1750 hz (for opening repeaters)

- Like every other handheld: useless original antenna. 

- When scanning, it will continue to scan after 5 seconds even if it’s traffic on the frequency. 

The last year I bought 8 of these radioes on all work great! Can use if for hunting, amateurradio and even listening at the police, firedepartment etc.

PS: This radio work like a dream in a APRS setup. (GPS Tracking)

One day I surfed by http://www.asiaradiosales.com and I found this excellent and cheap CB radio. (27mhz). This is a lowcost 40 channel CB radio. The pricetag is 55$ USD, include shipping! As you can see this is a rather simple radio, but this is much bang for the buck.

Puxing 777 – VHF or UHF, handheld radio.

Dec 22

Posted by admin in Transceivers | 1 Comment

Here you see a picture of the Puxing-777. This radio is DIRT CHEAP and are manufactured in Asia.  It’s  two versions of this radio. A VHF version, and a UHF.

I bought the VHF for 70$ USD from www.asiaradiosales.com earlier this year and this is the best handheld radio I ever had.  For 70$ you have a radio, beltclip, a desktop-charger and a battery. If you want better performance I recommend that you buy a longer antenna. I use a 42cm long 2m/70cm antenna from Diamond and I am very satisfied with this setup. 

I can buy 4-5 of these radioes for the price of ONE Icom / Kenwood / Yaesu. So you really don’t mind of you drop the radio to the ground and so on.  

Some friends of mine use these radioes for hunting, maritime and as a police scanner. (They only receive!) so this is a multi purpose radio. Can easily program the radio by hand, or via a computer-interface. The puxing 777 also support repeater splits and CTSS tones.  Some versions have 1750hz for opening ham radio repeaters. 

buy one at www.asiaradiosales.com . Fast delivery and shipping included in the price !!

KK5DR Review:  http://www.kk5dr.com/reviews/7K.pdf 

Youtube: http://uk.youtube.com/results?search_query=ic-7000&search_type=&aq=f

 

I bought one of these for a fixed installation at my QTH and this is one great little rig. It have a marvelous receiver and put out 100 watts with no problem. One drawback is the high current draw on receive and that is bad when you are portable on batteries. The thing I love about this radio is the IF DSP that is amazing.  The Icom ic-7000 are in another league than the old icom ic-706.   See under for specifications  from Icom America.

There is also an optional GPS unit and antenna with loads of features. This radio supports APRS 1200/9600 bps data communication (B band only). Like the VX7R, the VX8R is submersible and meets IPX57 specifications (3 feet for minimum of 30 minutes). A powerful 7.4 V 1100 mAh Lithium Ion battery is included. This HT is small, intuitive tooperate only 2.36 x 3.74 x 0.92 inches (thinner than VX-7R). It supports simultaneous independent 2-signal dual receive function with both V + V or U + U. It has weather band receive with Weather Alert. A barometric sensor is included. You can even operate Amateur radio whilereceiving FM broadcasts! The receive coverage is wider than VX-7R, with an independent AM/FM broadcast receiver circuit. The dot matrix LCD display provides Memory tag up to a maximum of 16 characters. You even get a high-resolution Spectrum Analyzer with ±60 channels indication with wave monitoring of received/modulated signal! And DCS and CTCSS encode and decode is standard.

The VX-8R comes with the SMA antenna, FNB-101LI Lithium Ion battery pack, belt clip and NC-86B battery charger. (The NC-86B should only be used for receive, because it is not capable of supplying sufficient current to support transmit).
