Brent’s initial impressions of the CQHAM TB-BOX

Many thanks to Brent (VA3YG) who writes:

Hello Thomas,

The Fedex courier just left my driveway. I ordered the CQHam TB box on Feb 29 and paid the $39 US for Expedited International shipping vs the Free Speedpack shipping from Hong Kong that promised it by June 1.  I really don’t like waiting for a parcel to arrive! Lol

I know there was some interest on your site about this product, so I thought I would write and give you some brief, first impressions.  Sadly,  I don’t have any more time to play with it until next week as I’m about to leave now to visit friends.

It arrived in 10 calendar days, well packed and everything inside survived the Fedex journey from Hong Kong to Southampton ON via Anchorage AK and Memphis TN.

No one would ever mistaken this equipment for gear made by Elecraft or Icom but it appears to work just fine. The variable capacitors are not smooth and the fit and finish is okay at best but I think, if you’re careful with it, and do your adjusting carefully, it should last you some time.

The “faux” leather case is actually quite nice and reminds me of the Yaesu FT-817 case.  As a bonus, a telescopic whip was included.

The batteries came charged and the rig showed 11.3vdc. I didn’t remove the battery tray as it didn’t want to slide out willingly and I didn’t want to force it. I’ll try that later when I have more time….

I connected my 43’ ZeroFive vertical with 30 radials to it and was able to tune from 80m right up to 10 meters with no problem.

I made a nice contact (my first phone contact in about 8 yrs) on 17 meters with a station in Biloxi.

It should be fun and it’ll give me an excuse to work the 817 again.

73 fer nw,

  1. I’m wondering, is the wiring complete on the tuner ? From the pictures it looks like the right cap is not wired.

    Enjoy and tnx for the info.
